I am an entomologist working on honey bee nutrition, impacts of pesticides, pests and pathogens on honey bees and honey bee behavior and biology. I employ various research techniques across multidisciplinary fields such as molecular ecology, neuroethology, insect physiology, ecotoxicology, mass spectrometry based multiomics and apicultural practices to address my current research questions. I am also interested in extending my expertise to studying insect pests.
