Sanjeewa Gamagedara, Ph.D.
I received my B.S. (Hons) degree in Chemistry from the University of Peradeniya, Sri Lanka and my Ph.D. in Analytical Chemistry from Missouri University of Science and Technology, Rolla, Missouri. The main goal of my research is to apply analytical chemistry techniques in aiding the betterment of human health. My research is mainly focused on the investigation of biomarkers for non-invasive early diagnosis of cancer. Other than that, I have research expertise in Metabolomics, Microfluidics, Environmental Analysis, and Pharmaceutical Analysis. I utilize various analytical instruments like LC-MS/MS, HPLC, CE, GC-MS, Atomic Absorption Spectroscopy, Lab-on-a-Chip devices for my research. Currently, I teach Instrumental Analysis Lecture and Lab classes.
