Protein synthesis involves the translation of ribonucleic acid information into proteins, the building blocks of life. The initial step of protein synthesis consists of the eukaryotic translation initiation factor 4E (eIF4E) binding to the 5' cap of mRNAs. However, many cellular stresses repress cap-dependent translation to conserve energy by sequestering eIF4E. This raises a fundamental question in biology as to how proteins are synthesized during periods of cellular stress and eIF4E inhibition. Research in our laboratory will build upon the discovery that cells switch to an alternative cap-binding protein, eIF4E2, to synthesize the bulk of their proteins during periods of oxygen scarcity (hypoxia).

Dysfunctional lipid metabolism is a key feature of cardiometabolic diseases, such as obesity and type 2 diabetes. My research program has three primary areas of interest:
First, we are using cell and mouse models to determine how omega-3 fats regulate lipid metabolism. We are investigating how omega-3 fats control adipogenesis, as well as lipogenic, lipolytic, and triglyceride synthesis pathways in adipose tissue and liver.
Second, we are studying how different nutrients regulate omega-3 synthesis in the body using both mouse models and human clinical trials.
Third, we are interested to personalize nutrition to improve human cardiometabolic health. We continue to be active in this area through various national and international collaborations.
