Diogo M.F. Santos is an Invited Assistant Professor at Instituto Superior Técnico (IST, Universidade de Lisboa) and a Researcher at the Center of Physics and Engineering of Advanced Materials (CeFEMA), studying electrodes and membranes for application in direct liquid fuel cells. 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 was devoted to developing the direct borohydride fuel cell. He did a 3-year post-doc in Chemical Engineering at FEUP (Porto University) and IST, studying new electrocatalytic materials for hydrogen production by alkaline water electrolysis. Afterward, he did a 2-year post-doc in Materials Science & Engineering, developing cathodes for direct borohydride fuel cells in 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 170 journal papers and 96 conference proceedings. His current h index is 35 (SCOPUS). Since 2020, D.M.F. Santos has been included on the “World’s Top 2% Scientists” list of Stanford University. He has presented 75 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 3 Ph.D. students and 5 M.Sc. students. He has completed the supervision of 1 Postdoc researcher, 1 Ph.D. student, 21 M.Sc. students, and 20 research internships. 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 main research interests relate to electrochemical energy conversion and storage.
