Research Summary/Interests

My research interest is on developing and analyzing biomolecules using Mass Spectrometry (MS)-based technologies. Currently, I focus on developing highly sensitive and selective high-resolution (HR) MS methods to biomonitor the exposure of carcinogens from environmental and dietary sources in human. Working with Dr. Turesky, my current projects include quantifying heterocyclic aromatic amines (HAAs), which are potential human carcinogens formed in well-done meat, and other environmental carcinogens in human hair; detecting DNA adducts of environmental and dietary carcinogens in fresh frozen or formalin-fixed paraffin-embedded animal and human tissues via targeted and untargeted approaches; and developing comprehensive screening methods to analyze the metabolome and proteome changes in cells treated with carcinogens.
