Dr. Anand Jayakaran

Program Lead, Low Impact Development

Anand “Ani” Jayakaran currently serves as an Associate Professor in the College of Agriculture, Human, and Natural Resource Sciences–Washington State University Extension. His role is to meet extension and research needs in a region experiencing the impacts of high urbanization, drought, and a changing climate. The scope of his work extends to the entire state of Washington, and involves disseminating strategies to manage water resources using Low Impact Development, and improving current engineering designs with ecosystems-centric solutions for handling stormwater through applied research. He was previously tenured-faculty at Clemson University's Baruch institute of Coastal Ecology and Forest Science in South Carolina. Ani holds a Bachelor's degree in Civil Engineering from India, and graduate degrees in Civil Engineering (MS) and Agricultural & Biological Engineering (PhD) from Ohio State University. He is a licensed Civil Engineering in the states of Washington and South Carolina. Ani's areas of academic interest are green infrastructure, best management practices (BMP), watershed hydrology and fluvial geomorphology, specifically with respect to improving stormwater infrastructure in watersheds impacted by urbanization.
