Jotham Suez

JOTHAM SUEZ, M.Sc., Ph.D., is the inaugural Feinstone Assistant Professor in the W. Harry Feinstone Department of Molecular Microbiology and Immunology. Dr. Suez’s research includes a seminal paradigm-shifting discovery related to the effects of non-caloric artificial sweeteners on the gut microbiome, thereby leading to impacts on obesity and the metabolic syndrome. In this ground-breaking project, he has been the major driving force in performing multiple in-vitro and in-vivo experiments as well as human studies in a rapid and high-quality manner. Dr. Suez’s discoveries are considered transformative to both basic science and human health and have been reproduced by dozens of follow up papers. Dr. Suez research aims to understand how the interaction between gut microorganisms and the environment can be harnessed for promoting precision medicine. In addition to identifying the individualized effects of non-caloric sweeteners on human health, Dr. Suez demonstrated microbiome-mediated, person-specific colonization resistance to common probiotics. Furthermore, his work in humans and mice surprisingly demonstrated that following antibiotics, probiotics delay, rather than facilitate, the recovery of the gut microbiome. Dr. Suez’s findings highlight the importance of considering the microbiome to improve the efficacy and safety of common therapeutics.

Dr. Suez received his M.Sc. in Clinical Microbiology & Immunology from Tel Aviv University in 2012, and his Ph.D. in Immunology from Weizmann Institute of Science in 2018. In 2020, Dr. Suez received the NIH Director’s Early Independence Award.
