Sergiy Libert is an Assistant Professor in the Department of Biomedical Sciences. He received a B.S. degree in Physics from Kiev-Mohyla Academy, Kiev, Ukraine in 2001, a M.S. degree in Physics from Clarkson University, Potsdam, NY in 2003, and a Ph.D. degree in Cell and Molecular Biology from Baylor College of Medicine, Houston, TX in 2007. He did his postdoctoral research at the Massachusetts Institute of Technology, Cambridge, MA from 2007-2013. In 2014, he was appointed as an Assistant Professor in the College of Veterinary Science at Cornell University.

Research Description

Most living organisms, including humans, age. Over time the ability to do physical and intellectual work deteriorates, and susceptibility to infectious, metabolic, and neurodegenerative diseases increases, which leads to general fitness decline and ultimately to death. Work in model organisms has demonstrated that genetic and environmental manipulations can prevent numerous age-associated diseases, improve health at advanced age, and increase life span.

My laboratory uses a diverse range of techniques to study the process of aging. We use mouse models, cell culture, biochemistry, and computational methods to better understand normal and pathological processes that accompany human aging, and to develop interventions to delay aging and ameliorate age-related diseases such as cancer, metabolic syndrome, and neuro-degeneration.
