CEHHS Welcomes New Faculty: Ahmed Bettaieb in Department of Nutrition

Ahmed Bettaieb is an assistant professor in the Department of Nutrition.  Ahmed studied cancer biology and chemotherapy at the University of Quebec in Montreal Canada. He did postdoctoral training at the University of California studying obesity, diabetes and cardiovascular diseases.  His previous training has afforded him a strong knowledge and technical background making him a well-trained scientist with the capabilities of producing more mechanistic advances in the treatment of metabolic disorders.

The long-term objectives of his research are: (1) provide a better understanding of the molecular and genetic mechanisms contributing to the development of metabolic diseases. (2) Exploit novel genes and therapeutic strategies aiming at reducing the overall burden of these diseases.
