Research Interest

I am interested in understanding the interplay between chemical exposure and nutritional or lifestyle habits,  such as diet selection and physical activity. To achieve this we utilize DNA and protein adducts to  study carcinogen metabolism, how it is modified by nutritional components and the underlying mechanisms regulating corresponding enzyme activities. In addition studies investigate exposures related changes in common metabolic pathways, using targeted and un- targeted mass spectrometry based metabolomic approaches.
