Research Interest

I am interested in understanding the interplay between chemical exposure and nutritional or lifestyle habits (for instance, diet selection and physical activity) on adverse health outcome such as lung cancer. To achieve this, we apply mass spectrometry and nanopore technologies to measure DNA and protein adducts to better understand exposure and metabolism of carcinogens, how it is modified by nutritional components, and the underlying mechanisms regulating corresponding enzyme activities. In addition, we investigate exposure related changes in common metabolic pathways using targeted and un-targeted mass spectrometry based metabolomic approaches. The long-term goal of my research is to understand metabolic reprogramming of metastases to identify novel therapy targets.
