Prof. Sultana N. Nahar ot The Ohio State University (OSU), USA, a co-founder of atomic astrophysics field, studies the four dominant atomic radiative and collisional processes, such as, radiative transitions, photoionization, electron-ion recombination, electron impact excitation, in astrophysical plasma, X-ray spectroscopy for Bio-medical applications, spectroscopy of kilonovae emission, diagnostics for bio-signature elements in exo-planetary atmosphere, with high accuracy methodology. She has made fundamental contributions to these processes in characterizing resonant features, developed algorithm for theoretical spectroscopy, developed precise unified theory for electron-ion recombination process with A. K. Pradhan at OSU. Findings of their studies are accumulated in the textbook “Atomic Astrophysics and Spectroscopy” (Cambridge U press). Her results from large scale computations are archived in her database, NORAD-Atomic-Data, at OSU. She is active in STEM education and research globally through research training, lectures, introducing and sponsoring programs. She is the founder of the International Society of Muslim Women in Science with members from 33 countries.

Eltahir is H. M. King Bhumibol Professor of hydrology and climate, and professor of civil and environmental engineering at the Massachusetts Institute of Technology (MIT). Eltahir made significant contributions defining the role of land surface processes in climate system. He has been actively engaged in projecting future impacts of global climate change at local and regional scales, with the objective of informing and hence enabling proactive adaptation by local communities. Examples for topics of his projections include: water in Nile basin, malaria in Africa, droughts over Mediterranean, and extreme heatwaves in Asia. Eltahir is the director of the UM6P-MIT Research Program at MIT with a focus on sustainable development in Africa. He is also the lead principal investigator in a large Climate Grand Challenges Project at MIT with the goal of reinventing adaptation to climate change. He was recently elected Member of the US National Academy of Engineering. Eltahir is a recipient of the Kuwait Prize in Applied Science in 2000, an elected Fellow of the American Geophysical Union (AGU) in 2008, and a recipient of the Hydrologic Sciences Award in 2017, from AGU.
