In 2020, she won the OWSD-Elsevier Foundation Awards for Early-Career Women Scientists in the Developing World.

Alexander Birbrair received his bachelor’s degree in biomedicine from Santa Cruz State University in Brazil. He completed his PhD in neuroscience at the Wake Forest School of Medicine. Then, he joined as a postdoc in stem cell biology at Albert Einstein School of Medicine in New York. His laboratory is interested in understanding how the cellular components of different tissues function and control disease progression. His group explores the roles of specific cell populations in the tissue microenvironment by using state-of-the-art techniques. In 2018, Alexander was elected affiliate member of the Brazilian Academy of Sciences, and, in 2019, he was elected member of the Global Young Academy, and in 2021, he was elected affiliate member of TWAS. He is the Founding Editor and Editor-in-Chief of Current Tissue Microenvironment Reports, and Associate Editor of Molecular Biotechnology. Alexander also serves on the editorial boards of several other international journals.

Dr Blair is a policy adviser for S&T and R&D, applying her expertise and skills in academia and government to assist various triple helix R&D organisations for the advancement of research and innovation, knowledge management, S&T education, and international cooperation. She is an interdisciplinary professional with degrees in Environmental Studies & Anthropology (B.A., St. Lawrence University), Environmental sciences (MSc, University of Arkansas), Freshwater Systems Science (MSc, University of Glasgow), and Earth Sciences (PhD, University of Glasgow). Her PhD research was to describe and model the behaviour of microplastics in fresh- and wastewater systems and to inform policy, publishing her original work in three peer-reviewed journals before the end of her PhD. She has worked as Chief Science Officer creating the R&D Unit and developing institutional processes for the Ministry for Science, Technology and Innovation in Honduras; and later, was Adviser for S&T for the Government of Honduras. Currently, she is Policy Officer for the Scottish Government's Hydro Nation Strategy and also guest editor for a special issue on microplastics pollution in the journal Frontiers.

Eric Djomo Nana is a Senior Researcher/Assistant Professor and Head of the Wildlife Research Unit at the Institute of Agricultural Research for Development in Cameroon. He is also currently a Research fellow in the Department of Biology at the University of Oxford in the United Kingdom. He holds a Bachelor of Science in Zoology and a Master of Science in environmental impact assessment from the University of Dschang in Cameroon and a Taught Masters in Parasitology from the University of Yaoundé I in Cameroon. He earned a PhD in ecology from Charles University in Prague, in the Czech Republic. His research interests are in wild meat use and trade and how that affect threatened species, local livelihoods, and facilitate spill over of highly pathogenic viruses. He has published several articles in peer-reviewed impact factor journals and has won several research grants and awards. He is an affiliate of the African Academy of Sciences and The World Academy of Sciences since 2021. He is the current President of Cameroon's chapter of the Society for Conservation Biology. He is also an adjunct professor at the Higher Institute of Environmental Science in Yaounde, Cameroon.

Al-Qadhi received her PhD degree with a major in oral biology from Cairo University, Egypt, and her research focuses on tissue regeneration using stem cells derived from oral tissues and evidence-based dentistry, a rare achievement for a woman from Yemen. Her master's project was about the effect of Khat extract on the oral tissues, as the habit of Khat chewing is a major health and social problem in Yemen. She has published several scientific articles in international journals. She received several awards, including the academic distinction for the highest-ranked undergraduate students, and a postgraduate scholarship from the Ministry of Higher Education and Scientific Research in Yemen. She was selected as a TechWomen emerging leader representing her country in the USA in 2014. She had worked as an assistant lecturer at the University of Science and Technology in Yemen. Now, she is looking to pursue her scientific journey as a researcher in stem cells and tissue regeneration in a safe environment where she can improve her technical skills, gain knowledge, and make a positive impact on her community as well as the host institute.
