Dr. Sivandran is a clinical assistant professor in Engineering with a specialization in the field of environmental engineering. Dr. Sivandran graduated in 2012 with a Ph.D. in Environmental Engineering from the department of Civil and Environmental Engineering at the Massachusetts Institute of Technology. Prior to obtaining his Ph.D., Dr. Sivandran worked as an environmental engineering consultant (International Risk Consultants, Perth Australia) focusing on environmental modeling and permitting for the oil and gas industry. He also volunteered for 6 months as a water and sanitation engineering delegate for the International Federation of the Red Cross and Red Crescent Societies (Banda Aceh Indonesia) in response to the Indian Ocean Tsunami in 2004.  For the last 4 years, he was an Assistant Professor within the Department of Civil Environmental and Geodetic Engineering at The Ohio State University.

Research Interests

His interests are directed towards understanding the complex and dynamic feedbacks between hydrology and ecology, and how these interactions may provide resilience against departures from stationary behavior caused by different disturbance or change scenarios. His approach to research begins with physical understanding of the coupled hydrologic-ecologic system, which is strongly dependent on lab experiments, field campaigns and remote sensing observations, followed by numerical representation using mechanistic models to upscale point processes to the catchment scale. Our work aims to expand the foundation of hydrologic science and thereby inform engineering solutions for better land and water resource management.
