In September 2021, I was nominated for the PAPSSN nomination for the mobility program. Unfortunately, I heard this good news about my PhD scholarship from my friend too late.

The sun hadn’t yet risen in Tigray, Mekelle. Ethiopian and Eritrean troupes invaded the place. The network, internet, bank, and transportation were all blocked. I tried to contact my supervisor (Prof Franchi then at BIUST) every day by asking for help from the World Food Program and another NGO worker (e.g., Dr. Desalegn). They helped me check my email, but it was difficult, and they could help me only when I gave them my password and the details of my email account… I communicate them what to write and then they’d sent it to him. I waited for weeks in order to check for his replies. I spent long and exhausting months in this way, and I want to appreciate the patience of Prof Franchi. He always understood me and gave me hope; he said, “Don’t worry, we will find another way”. Imagine that. He wrote an email to the head office of the World Food Program Mr. Bernard and Mr. Levan, but they couldn’t help me. But that communication was essential, as they became enthusiastic about assisting me in gaining access to the internet for further communications.

I arrived in Botswana after overcoming numerous challenges. There have been days along my road when I have been stuck, confused by the overwhelming situation and unsure where to go or what path to take, I kept repeating myself ‘everything will pass’, and regardless of all the danger I am confident that my dreams will come true one day. I grew up in a culture that did not encourage education; everyone said, “Why are you taking this risk?”, but I didn’t care; I wanted to try it, I had to… Staying where I was meant facing inevitable hardship, and I had already lost my big brother and my dear friend “Hawaz” who once shared hopeful news with me. His fate served as a painful reminder of what could have happened if I had stayed. By taking this leap, I knew I had at least a 50% chance of success and that was worth fighting for.

“So, you want to go?” my father asked me in November 2022. “Yes, I want to try it and start my journey to achieve my goals”. I rushed to gather my things and drove out of Mekelle. Finally, I find that each little victory gives me the strength to push on when life gets tough. The situation forced me to make the difficult decision to leave my place, my family. I headed to the border and planned to use the invitation letter from BIUST to help me out of that situation as nobody was allowed out of Tigray. This would have been impossible without the help of PAPSSN and my great supervisor, Prof. Fulvio Franchi. It’s hard to find your way out of a war zone without money, hence he took the risk and he sent me 900 euros to get out of that situation safely. It was done, I was out of the war.

Life in Botswana

Finally, on January 14, 2023, I safely arrived in the peaceful country of Botswana. Already, my supervisor had assigned Ms. Portia from the International Linkages and Partnerships Department to pick me up at the airport in Gaborone. On campus, she prepared a room at the Botswana International University of Science and Technology (BIUST), Palapye. Once I was done with the accommodation and immigration processes for the student permit, I enrolled as a postgraduate student at BIUST. I was introduced to the another PAPSSN scholarship holders, and I have developed positive relationships with colleagues and my Makgadikgadi team. This relationship has helped me to overcome the hardships of my past life.

Writing my personal blog and tell my story to the world is one of many other things I wish to do. When I thought of starting a new life as a PhD student on my own in January, I was frightened. But I must always remember that I was troubled when I was on the worst journey of my life, and despite all those troubles now I am here writing this blog, sitting in a nice room in a peaceful and beautiful Botswana.

Some laboratory works at BIUST, analyzing sediment samples, examining ostracods, and presenting findings at an academic conference with my team and working in well-equipped and comfortable environment.

My research work so far…

I’m realizing more and more that time doesn’t wait, and that pushes me to embrace both the personal and academic journey ahead. Pursuing a PhD is a transformative experience: it’s not just about research, but about growing from a student into a future scholar and faculty member. I know it won’t be easy, but I truly believe it will be worth it. I’ve already embarked on my research journey, and with time, I feel like I’ve finally grasped the deeper purpose of my PhD it’s truly fascinating. Right now, I’m focused on analyzing my results, diving deeper into the complexities of my project: “Biostratigraphy and Sedimentological Characterization of the Late Pleistocene-Holocene Playa Lake Deposits, Makgadikgadi Basin, Northeastern Botswana: Implications for Paleoenvironmental and Paleoclimate Reconstruction”.

My supervisors tell me I’m on the right track, and despite all the challenges, they continue to support me. I know I’ve tested their patience with my revisions and mistakes, but they never give up on me. They believe that, with time, I will grow stronger in my writing and communication. That unwavering belief in me means a lot. But if I’m being honest, I’m the one who sometimes feels like giving up. Then I remind myself how far I’ve come and how much my mentors have invested in me. I tell myself, “Trhas, stop complaining, stop procrastination, and work hard. Be proud of the people who lift you up and make you smile.” That’s my personal motivation. And no matter what, the motivation from my supervisors is always there.

PAPSSN effort

As part of the PAPSSN Mobility initiative to support meaningful research projects, I was fortunate to receive a brand-new laptop through my research budget. The scholarship also provides crucial financial support, including a settlement allowance of 900 euros, an additional 900 euros dedicated to female scholars, and a 900-euro monthly stipend.

I am deeply grateful to the Pan African Planetary and Space Science Network (PAPSSN), especially Prof. Fulvio Franchi (now at the University of Bari, Italy) and Mrs. Chakandinakira Gadibotsile (BIUST) the project coordinators and the entire selection committee. Their patience and willingness to give me not just a second, but even a third chance, have allowed me to become a beneficiary of this incredible project.

Additionally, I extend my heartfelt appreciation to the Botswana International University of Science and Technology community, as well as all my friends and colleagues, for their unwavering support.
And of course, I am thankful that Botswana is such a peaceful country, full of kind and welcoming people!

Thank you for giving me the opportunity to share my story, it truly means a lot! 

Peace for all!!!

Departure day, all smiles!
Departure day, all smiles!

I found out about the PAPSSN scholarship opportunity a few days after declining another remote exploration job opportunity. My daughter was only 6 months and the mum guilt just wouldn’t budge despite my love for geology. I shared my thoughts with a friend, and she told me about the PAPSSN scholarship—soon after, I applied. PAPSSN provides topics of research to select from, which cuts down one’s time on reading broadly in search of a topic. From several interesting options, I was drawn to research supervised by Dr Linda Iaccheri and Dr Stephanie Enslin on creating a geospatial database for mine tailing in South Africa using remote sensing and GIS tools. With each paper I read on the topic, I realized this scholarship would open doors to a research-driven field aligned with modern technological advances. It offered exactly what I needed—an escape from purely field-based geology to a career that could blend geology with office-based work, giving me the flexibility to stay closer to home and support my family.

The PAPSSN’s application process was straight forward, and the support was very responsive to any question regarding the process. Once I finally sent through my application applied, I took a short prayer and left the rest to God. Fast forward a few months later, I received the great news that my application was successful and needed to get started on the processes preparing for my Msc academic Journey at the University of Witwatersrand in Johannesburg, South Africa. I left for South Africa with all the enthusiasm to make the best of this opportunity, as shown by image below, I was all smiles on the departure day.

Embracing a New Environment

Johannesburg is fast paced and has a very mixed culture. I come from a slower paced city, Gaborone, Botswana but settling into the new environment was seamless through PAPSSN’s proactive contact person at Wits- Mrs Suraiya Buccas, together with the BIUST team as they had prepared me for a smooth registration process and shared all relevant information to make this transition seamless. They provided a prioritized checklist of everything I needed to do before leaving Botswana and what to upon arrival in Johannesburg.

Personal Development and Academic Growth

PAPSSN also has a great selection of Supervisors who not only prioritize academic excellence, but personal development. Dr Linda Iaccheri and Dr Stephanie Enslin have a shared commitment with PAPSSN for Pan-Africanism in Planetary Space science therefore they constantly push me to step out and occupy space in this huge industry. Evident from images below, A few months into my academic journey they had me submitting my proposal, conference abstracts, posters, motivational letters to attend conferences whilst doing all sorts of training which sharpened my technical skills and broadened my view of what science can do for Africa. Through this commitment, I’ve also met with brilliant peers from across the continent—each with a vision to solve local problems through tech driven approaches.

PAPSSN’s mission to build African capacity in planetary and space science is not just a vision on paper—it’s something I’m living. Through their support, I’ve transitioned into a research path rooted in remote sensing and GIS, working on environmental challenges tied to mining and sustainability. To future scholars especially women: embrace the unknown, challenge yourself, and remember that this scholarship is more than financial aid—it’s a platform to shape your destiny and make Africa proud. Don’t let mum guilt rob you of a career you love.

After my undergraduate studies, I had an opportunity to work as a research assistant at Botswana International University of Science and Technology (BIUST). During my time at BIUST as a research assistant in Prof Franchi’s team, I come across an advertisement of the Pan-African Planetary and Space Science Network (PAPSSN) scholarship and I applied. The application was not overly difficult; it involved meeting several criteria, and I had the opportunity to be among the first intakes for the MSc program at Copperbelt University in Zambia, as it was a highly competitive scholarship. All arrangements from travels to insurance were done at BIUST before I went to Zambia. On August 21st, 2022, I left Botswana to begin my 24-month MSc program at the Copperbelt University in Zambia, where I pursued a Master of Philosophy Degree in Geology involving the investigation of meteor impact crater lakes in Zambia. I quickly settled in at the university’s post graduate campus hostels, a few kilometres away from the main campus in Kitwe, Zambia. Life in Kitwe was quite vibrant and bustling. Kitwe is a major industrial and commercial town mainly known for its mining activities. It is considered a peaceful town with low crime rate and affordable accommodation. During my stay there, I experienced firsthand the warmth and hospitality that Zambians are known for. The town also offered social amenities where my newfound friends and colleagues would play football, watch both local and international football leagues and go swimming. I and my colleagues would visit an orphanage with arms full of books, food and clothes. We spent most of our Saturdays reading stories and teaching them English and Mathematics for different age groups. Playing games and just talking with the kids, hearing their dreams and ambitions. The whole experience was heartwarming and eye-opening, reminding us of the importance of sharing our resources and time. 

Pursing a Master of Philosophy in Geology at The Copperbelt University in Zambia has been a journey of endless discovery and intellectual challenge. It is like peeling back the layers of the Earth, revealing secrets that have been locked away for million of years. My research on investigating Lake Bangweulu as a possible candidate for a meteor impact has been particularly thrilling. In preparation for my study, I had to dive into satellite imagery, geological maps, geophysics anomaly (gravity and magnetic) maps, piecing together to find good point to sample from. The study was carried out to ascertain how the massive basin was formed. Navigating the challenges of fieldwork in the Bangweulu Basin has been a remarkable learning experience. Much of the basin is flooded, making direct observation of bedrock exposures or outcrops difficult. Field visits were conducted, and samples from the basin were collected for geochemistry and petrographic analyses. Results showed no evidence of shock metamorphism, and the Bangweulu basin samples do not exhibit unusual siderophile or platinum group elements, indicating no external origin. Aeromagnetic data and gravity data, supported by geological mapping and petrographic analysis, confirm the presence of shallow granitic and quartzite-volcanic formations. Structural analysis shows the presence of NW-SE trending regional fault systems. Bouguer gravity and aeromagnetic anomalies, show no evidence of a meteor impact event. Interpreting results felt like solving a puzzle where every piece brings new insights and raises new questions.

The most rewarding part was knowing that this research could contribute to our understanding of Earth’s history and the forces that shape its surface. I also acquired new skills and techniques in geophysics, petrography, geochemistry and Arc GIS. Finally, I had the privilege of presenting my work at two conference workshops; 2023 International Space Weather Initiative School at Lusaka, Zambia and 32nd International Astronomical Union General Assembly 2024 at Cape Town, South Africa. 

This whole 24-month experience helped me build relationships and I am grateful for every moment. Thanks to my supervisors at CBU for their guidance and patience, thanks to Ms Chakandinakira and her team at BIUST for the support throughout my PAPSSN scholarship…and thanks PAPSSN!

Before I received the PAPSSN scholarship, my life was a mix of dreams, challenges, and unexpected turns. In 2021, I graduated with first-class honors in Astronomy and had plans to pursue my studies abroad. But as life would have it, things didn’t go as planned. With opportunities dwindling, I decided to pursue a Master’s degree in my home country, Sudan. I spoke with one of my university lecturers, who agreed to become my supervisor. We began discussing research topics, and after submitting my proposal, it was accepted.

However, just three months later, war broke out in Sudan, and it started right in the area where I lived. Life became a struggle for survival. Access to basic resources like electricity and the internet was scarce, making communication with my supervisor nearly impossible. My academic journey seemed to stall. But amidst all the chaos, my supervisor, Dr. Hassan Abdullah, suggested that we search for scholarships to allow me to continue my research abroad.

That’s when we reached out to my current supervisor, Dr. Adams Duniya, at BIUST. We shared similar research interests in cosmology, which gave me a renewed sense of excitement. Initially, the plan was to visit BIUST for six months, but after persistent efforts from Dr. Fulvio and my supervisors, we secured a full two-year PAPSSN scholarship.

The day I received the acceptance letter was filled with relief and joy. For me, the PAPSSN scholarship was not just an opportunity for academic advancement, it was a lifeline. The war in Sudan had brought so much uncertainty, but this scholarship was my chance to escape the conflict and rebuild my academic journey.

Preparing for my move to Botswana was both exhilarating and nerve-wracking. It was hard leaving my family and country behind, especially under such difficult circumstances, but I knew it was a step I had to take.

\When I arrived at BIUST, I was greeted with warmth and support from both the staff and the PAPSSN coordinators. The sense of community at BIUST, especially with fellow scholars from all over Africa, made me feel at home. Of course, settling into a new academic environment had its challenges. There were moments of doubt as I adapted to the new culture and academic system. But through it all, the support I received, especially from my supervisor Dr. Duniya kept me grounded. His guidance and mentorship have been invaluable, and I’m incredibly fortunate to work with someone so dedicated.

Today, I am fully immersed in my research on cosmology, focusing on cosmic magnification as a cosmic probe. The journey has been intense but rewarding. Every day, I feel more connected to my purpose and the larger scientific community. The PAPSSN scholarship has opened doors I never imagined, and I am deeply grateful for this opportunity.

Looking back, the challenges I faced before coming to BIUST have only strengthened my resolve. This scholarship didn’t just change my academic trajectory, it gave me hope. I’m excited to see where this path leads and look forward to contributing to the world of Astronomy.

As I reflect on my journey, I am overwhelmed with gratitude for the incredible opportunity the PAPSSN Scholarship has afforded me. Studying abroad was a dream I never thought I’d realize, but this scholarship made it possible. Little did I know that this life-changing journey would take an unexpected turn when I found out I was pregnant before traveling to participate in the scholarship opportunity for a master’s degree at Botswana International University of Science and Technology (BIUST). I was faced with doubt about how I’d manage, but I was rendered support not only by my husband but also by professor Mengistu, Mrs. Chakandinakira, professor Fulvio and the team. In this blog article, I want to share my story of how the PAPSSN Scholarship not only enabled me to pursue my academic dreams but also helped me navigate the challenges of motherhood while abroad.

Since I was able to reason, I’ve wanted to be a scientist and leave a lasting legacy on the planet. To change the world, you must have lofty goals that push you out of your comfort zone. I received my BSc in Physics from Copperbelt University in Zambia, where one of my lecturers noticed my interest in Astrophysics and later advised me to take this chance. After receiving the scholarship, I realized I would become a mother. That’s when doubt and worry seized me about the decision I was about to make; fortunately, the host team provided guidance on which path to choose.


Because the astrophysics department had not yet been established when I was admitted to the university, I was assigned to the environment science department. A whole new field to me, and I had to learn the fundamentals from the beginning. As the department attempts to solve real-world challenges, I soon adapted. Although the material is voluminous, it became easier to traverse with the help of my supervisor and lecturers. Learning new abilities can be difficult to the point when I begin to doubt myself, but in the end, determination and hard effort triumph.

The scholarship’s support network proved to be a lifeline during this challenging period. The friends I made in my host country, many of whom were fellow scholarship recipients, became my extended family. They offered emotional support, invaluable advice, and practical assistance. We shared in the joys and tribulations of academic life and motherhood, forging bonds that will last a lifetime.

The scholarship organization itself also played a pivotal role. They provided guidance on navigating the educational system in a foreign land, ensuring I had the resources needed to excel academically. Moreover, their understanding and flexible approach during my pregnancy was a testament to their commitment to the holistic well-being of their scholars.


In the end, the PAPSSN Scholarship is doing more than just enable me to obtain a world-class education; it is transforming my life. I will not only graduate with a master’s degree but also became a stronger, more resilient individual, a loving mother and wife. This scholarship has taught me the power of community, resilience, and the importance of pursuing one’s dreams, even in the face of unexpected challenges.


In conclusion, the PAPSSN Scholarship is more than financial assistance; it is a lifeline for not only women like me but fathers, sons and daughters who dream of pursuing higher education and who face life’s unforeseen twists and turns. It’s a symbol of hope, empowerment, and resilience. My journey, though filled with challenges, has been a testament to the transformative impact of this scholarship. I am forever grateful for the opportunities it has provided and the remarkable people it has brought into my life. Special thanks to Professor Mengistu for his support and guidance towards my research work.

It is with great pleasure to announce the successful applicants for the PAPSSN Scholarship, third call 2023. We received an overwhelming number of applications from highly talented and deserving individuals, making the selection process quite challenging. After careful consideration, our esteemed panel of judges has chosen a remarkable group of scholarship recipients who have demonstrated exceptional academic prowess, potential, and a strong commitment to their chosen fields.

Before graduating from college, my ideal career was working as a geophysical prospector. My master’s degree from the University of Khartoum in 2019 was, in fact, the first step. I moved to Johannesburg in 2021 with my husband and he was a researcher at the University of Johannesburg’s Physics Department. At that time, I got another opportunity to carry on from where I had left off. I had the chance to meet Prof. Jeremy in the Department of Geology. He advised me to get in touch with Dr. Stephanie Enslin (Geophysics at the School of Geoscience, University of Witwatersrand).

The most wonderful thing at the time was to be in Johannesburg.

I contact Dr. Enslin and sent her all of my paperwork; the result was that she accepted me. But there had been a problem with the funds. I began looking for a scholarship but gave up soon after that. Then, one day, Dr. Enslin emailed me a call for application and informed me that the deadline was in 48 hours. It was the PAPSSN call. With the assistance of my supervisor, I got started right immediately and completed the document preparation in less than 24 hours.

The project’s title for was a real challenge, because I didn’t have the desire to studying satellites, nor earth observation. My husband, though, my closest confidant, said that the best way to succeed in life is to embark on an adventure and learn novel skills. My motivation to pursue a career in research and get my PhD from Wits was stronger than anything else, therefore I quickly finished the application and submitted on time.

I received acceptance letter in September 2021. 

I started immediately the admissions procedure for the University of the Witwatersrand. The first step of my PhD took place in March 2022, and I was immediately welcomed by the kindness and supportiveness that characterise my supervisor. The first step in the study process was carefully crafting a proposal, to which the supervisor and Co-supervisor, Prof. Khalied Adem, a lot of their time, sharing their experience and knowledge.

In November 2022, I attended the South Africa Geophysical Association (SAGA) conference, for me it was the first time in an academic meeting. In terms of academics and interaction, it was the best addition to my PhD programme.

PAPSSN, thank you so much. I appreciate you giving me this chance to experience a new culture, a valued community, and a brand-new study in every way.
