Dr. Padmanava Dash is an Assistant Professor in the Department Geosciences at Mississippi State University (MSU). He specializes in ocean color remote sensing, limnology, harmful algal blooms (HABs), harmful microorganisms (pathogens), toxic metals, nutrient flux, biological oceanography and ocean biogeochemistry. His broad research interests include describing the conditions under which water quality issues develop, assessing their ecological impacts, and developing management strategies for their mitigation. His current research focuses on studying water quality issues of inland lakes, estuaries, and bays of Mississippi and Louisiana, and studying ocean acidification in the ocean. His research includes field, laboratory, and in situ, Unmanned Aerial Systems (UASs) and satellite remote sensing research to study various HAB forming species, suspended sediments, colored dissolved organic matter (CDOM), pathogens, toxic metals, and nutrients to enhance the current state of knowledge on detection and mapping of water quality parameters and thus support state and coastal community efforts to manage human health and fisheries.
