Current research and/or projects

Dr. Sumarah is an analytical and natural products chemist with expertise in the isolation, structural elucidation and analysis of small organic molecules from complex biological matrices using LC-MS and NMR. This includes extensive experience on the characterization and analysis of fungal secondary metabolites. The majority of his current research is focused on the development and implementation of better tools using mass spectrometry for the detection and monitoring of mycotoxins in the food production system and agricultural contaminants such as pharmaceuticals in the environment. These tools are being used for discovery of new emerging mycotoxins and to provide data on the fate and occurrence of pharmaceuticals in the environment to regulators.
