Research Interest

My current research interest is forensic analysis of abused drugs, fire accelerants and toxicological specimens using ambient ionization mass spectrometry (AI/MS), gas chromatography mass spectrometry (GC/MS) and liquid chromatography mass spectrometry (LC/MS). A common theme in my research is to explore novel ionization techniques such as direct analysis in real time (DART), atmospheric pressure photoionization (APPI) and electron capture ionization (ECI) in forensic analysis. There are three major research focuses:  1) investigation of AI/MS for direct analysis of abused drugs and fire accelerants in the crime scène; 2) development of novel GC/MS and LC/MS methods for the analysis of biodiesels and vegetable oils; 3) exploration of GC/ECI/MS and LC/ECI/MS for trace level analysis of drugs in forensic toxicology and doping control.
