My research focuses on the development of mass spectrometry based analytical methods than can facilitate identification, structural elucidation and trace quantification of micropollutants in environmental samples.
I enjoy being a graduate student because it allows me to do an in-depth research on environmental issues that I am passionate about. I also enjoy the flexibility to work on various analytical problems and the opportunity to collaborate with scientists in different fields.
Outside of the lab, I enjoy traveling and outdoor activities as well as watching plays and musicals.
