Thomas D. Horvath, PhD

Personal Statement

Research Interests:

Dr Horvath’s efforts are keenly focused on the development of bioanalytical methods to measure endogenous and exogenous small-molecules and proteins from an assortment of biological fluids and tissue extracts. As a member of the TCH-Microbiome Center, he applies LC-MS/MS-based methods to examine how specific microbial-derived metabolites or proteins can benefit, impede, or be diagnostic of the human health condition. His interest is in developing targeted metabolomics methods has resulted in a number of publications that report how specific microbes can influence intestinal biology and modulate the mammalian gut-brain-axis.
