Walter Sandoval is a biologist from the National University of Asunción (FACEN-UNA) in Paraguay. In 2013, Walter earned his M.S. in Microbiology from North Carolina State University (NCSU), United States, through a Fulbright scholarship. In 2016, Walter earned his PhD in Microbiology, and his thesis was awarded the Kenneth R. Keller Award for the best doctoral dissertation of the year at NCSU’s College of Agriculture and Life Sciences (CALS). This focused on the physiology of bacteria that generate solvents for advanced biofuels and the capture of greenhouse gases (GHG). In 2017, Walter began his postdoc in Chemical Biology at Harvard University. His work focused on the manipulation of the human intestinal microbiota using small molecules. In 2020, Walter returned to Paraguay and leads the Microbial Biotechnology laboratory at FACEN-UNA, in addition to being a teacher, and coordinating projects between industry and academia. Likewise, along with the publication of various scientific articles, he has three patents, one at NCSU, and two at Harvard, which are related to the capture of GHGs, and the functional manipulation of microbiomes. In the private sector, Walter is Chief Scientific Officer (CSO) of MicroBios S.A. Recently, in 2022, Walter was selected as a Global Fellow of the Eisenhower Fellowships, for his work and its impact on translational research in Paraguay.
