Associate Professor, Assistant Dean of Medical Students 216.368.4967 (o)

I am an Associate Professor in the Department of Nutrition at Case Western Reserve University. I have been studying genetics and its impact on metabolic pathways for over 20 years. In the last 10 years I have focused on the genetic susceptibility to development of liver disease from obesity or alcohol.

In addition I am the Assistant Dean of Medical Student research and oversee the 4 month research requirement for the medical students. I also teach undergraduate, graduate and medical students the biochemical pathways that impact health and disease.

My lab focuses on the development of liver disease caused by obesity and insulin resistance or from chronic alcohol consumption. We have used novel research animals called chromosomal substitution strains (CSS) to identify novel genes involved in protection from liver fibrosis. Using whole body metabolism studies and molecular biology techniques we investigate how these genes impact metabolism and result in disease.

NTRN452/BIOC452:    Introduction to Biochemistry: From Molecules To Medical Science.   
Overview of the macromolecules and small molecules key to all living systems. Topics include: protein structure and function; enzyme mechanisms, kinetics and regulation; membrane structure and function; bioenergetics; hormone action; intermediary metabolism, including pathways and regulation of carbohydrate, lipid, amino acid, and nucleotide biosynthesis and breakdown. The material is presented to build links to human biology and human disease. One semester of biology is recommended. Offered as BIOC 307BIOC 407, and BIOL 407. Prereq: CHEM 223 and CHEM 224
