Diogo M.F. Santos is a Principal Researcher at the Center of Physics and Engineering of Advanced Materials (CeFEMA) and an Invited Assistant Professor at Instituto Superior Técnico (ULisboa, Portugal). His current research focuses on a three-way approach to low-cost green hydrogen by developing high-efficiency electrodes, membranes, and electrolytes. D.M.F. Santos was born in Torres Vedras, Portugal, in 1977 and graduated in Chemical Engineering at IST in 2001. He received an M.Sc. degree in 2006 and a Ph.D. in electrochemistry in 2009. His Ph.D. thesis focused on developing the direct borohydride fuel cell. He completed a 3-year postdoctoral fellowship in Chemical Engineering at FEUP (Porto University) and IST, where he studied new electrocatalytic materials for hydrogen production via alkaline water electrolysis. Afterward, he completed a 2-year postdoctoral position in Materials Science & Engineering, developing cathodes for direct borohydride fuel cells at IST and CICECO (Aveiro University). As an Investigador FCT in CeFEMA (2015-20), he developed low-cost electrocatalysts for low-temperature fuel cells. D.M.F. Santos has authored over 180 journal papers and 96 conference proceedings. His current h-index is 39 (SCOPUS). Since 2020, D.M.F. Santos has been included on Stanford University's “World’s Top 2% Scientists” list. He has presented over 90 oral communications and 80 posters at international conferences. He is a member of several renowned international societies and is a reviewer for over 80 scientific journals. D.M.F. Santos is the supervisor of 5 Ph.D. students and 2 M.Sc. students. He has supervised 1 Postdoctoral researcher, 1 Ph.D. student, 28 M.Sc. students, and 21 research interns. D.M.F. Santos has been part of the team of two P2020 projects (Inpactus, Clean4G), and is currently Working Group Leader of WIRE COST Action in “Waste biorefinery technologies for accelerating sustainable energy processes” (CA20127). His primary research interests focus on electrochemical energy conversion and storage.
