Brief bio and description of current research:

Ramesh Kanwar, is the Professor and Department Chair of the Agricultural and Biosystems Engineering Department at Iowa State University. He received his B.S. and M.S. degrees in agricultural engineering from India and Ph.D. degree from Iowa State University.  He joined the faculty of the agricultural engineering department at Iowa State University in 1981 and was promoted to full professor in 1991.  He was appointed assistant director of the Iowa Agricultural Experiment Station on January 15, 1997 and director of the Iowa Water Resources Research Institute on December 1, 1999 and served in these positions until September 15, 2001. He was appointed Chair of the Agricultural and Biosystems Engineering Department at Iowa State University on September 15, 2001.  He has worked as a consultant for the World Bank, European Commission, Global Environment Facility (GEF), United Nations Development Program (UNDP), United States Agency for International Development (USAID), NATO, FAO, and many foreign governments/universities.  These global opportunities have taken him to more than 40 countries.  He has taught BS, MS, Ph.D. degree students in Austria, Belgium, Portugal, Uzbekistan, and India.  He is an honorary professor at Beijing Agricultural University in China, Ningxia University in China, Tashkent Institute of Irrigation and Agricultural Mechanization in Uzbekistan, and Trakia University in Bulgaria. He was awarded an honorary doctorate degree by the Georgian State Agrarian University in Tbilisi, Georgia, in 2000 and was elected Fellow of the National Academy of Agricultural Sciences in India in 2001.  In 2005, he was elected Fellow of the American Society of Agricultural and Biological Engineers. In 2007, he was awarded Doctorate Honor Causa Scientific by the Trakia University in Bulgaria. He has received numerous awards including Engineer of the Year Award by ASABE, Distinguished Service Award by the Asian Association of Agricultural Engineers, and Outstanding Young Engineering Faculty Research Award, Outstanding Graduate Faculty Award, and International Service Award by Iowa State University.

Kanwar teaches undergraduate and graduate courses in the areas of water quality, and soil and water management, and erosion and sediment transport at Iowa State University.  He conducts research in drainage, irrigation, water quality impacts of agricultural and livestock production systems, hydrologic modeling, and natural resource engineering.  He has been a major professor for 28 M.S. and 25 Ph.D. students. He has authored more than 400 publications (150 refereed journal articles, 115 book chapters and conference proceeding articles, and 165 presented papers at international conferences).
