Dr. Padmanava Dash is an Assistant Professor in the Department Geosciences at Mississippi State University (MSU). He specializes in remote sensing and water biogeochemistry. His broad research interests include investigating the conditions under which water quality issues develop, assessing their ecological impacts, and developing visualizations for their management and mitigation. His research includes field, laboratory, Unmanned Aerial Systems (UASs), and satellite remote sensing approaches to study harmful algal blooms, suspended sediments, colored dissolved organic matter (CDOM), acidification, pathogens, nutrients, toxic elements and heavy metals to enhance the current state of knowledge on detection and mapping of water quality parameters and thus support federal, state and coastal community efforts to manage human health and fisheries.

His research group has developed a water quality visualization tool that can be accessed at https://www.water.geosci.msstate.edu/.
