I am a biochemist studying the biological interactions of sugars. Raised and educated in New York City, I received a B.S. in Biochemistry from nearby Stony Brook University in 1977. I then began a fruitful southerly migration, entering graduate school at Duke, where I worked with Robert Hill and obtained a Ph.D. in Biochemistry 1982.
I continued southward to UT Southwestern in Dallas for a postdoctoral fellowship with Michael Brown and Joseph Goldstein in 1983. This experience was highly rewarding for me, and I decided to stay at UT Southwestern, where I am currently a Professor in the Department of Pharmacology.
My training at Duke and UT Southwestern led me to an interest in glycobiology. This is an emerging field that studies essential roles of sugars, in all domains of life, but roles that are not directly related to nutrition or energy metabolism.
In glycobiology, we study well-known sugars like glucose, and lesser known structural cousins such as mannose, as parts of polymers (glycans). These glycans can be free, or covalently attached to proteins and lipids, and are recognized by highly specific glycan-binding proteins called lectins.
The glycans we study are amazing! They are critically involved in protein sorting and folding, cell-cell interaction, signaling, and pathogen binding, just to name a few examples.
There are approximately 100 human genetic diseases caused by mistakes in synthesizing these glycans! Currently, we are studying free glycans as signaling molecules, anti-viral agents, and inducers of autoimmunity.
