Shellfish ecophysiology, Algology
I am broadly interested in bivalve ecological physiology. A large part of my research focuses on understanding how suspension-feeding bivalves recognize, process, ingest or reject waterborne particles and how biological functions involving such mechanisms (e.g. food particle selection, symbiosis or defense against pathogens) are regulated. For example, we have been probing cellular and molecular processes mediating food uptake and particle selection in bivalves. Further, the role of neuropeptides and neurohormones in the control of glucose homeostasis has become a central part in my research. At the same time, I am also involved in several projects that aim to improve and boost shellfish aquaculture in New York and elsewhere. My research involves field work and experimental approaches on organisms, organs, cells and molecules (including next-gen sequencing and proteomics).
