Research Interest:
Recent interests include studies in pedagogy: developing curricula that would enhance our students’ appreciation for the importance of STEM disciplines in their lives. I am particularly interested in developing interdisciplinary curricula which would bridge the gap between precise disciplines such as mathematics, physics or computer science and biology and chemistry.

My scientific interests revolve around importance of broadly understood nutrition and its effects on development of chronic diseases as well as aging. I am particularly interested in the impact of energy imbalance (obesity) has on the process of carcinogenesis and aging.
