Dr. Rabi Mohtar is Executive Director of Qatar Environment and Energy Research Institute (QEERI). Before joining Qatar Foundation, Professor Mohtar’s professional activities addressed sustainable development, including efficient resource utilization and maintaining or improving environmental quality. Dr. Mohtar has held numerous senior positions including Full Professor at Purdue University in the US and Inaugural Director of the Global Engineering Program in the US. He has received numerous international research awards and honors. Dr. Mohtar’s research focused on conserving natural resources (including land, water, air, and biological resources) that face global challenges such as increasing food and water supplies for a growing population. He developed environmental and natural resources conservation engineering programs that evaluate the environmental impacts of land use and water management, developed innovative soil and groundwater remediation technologies, applied numerical methods to biological engineering systems, and characterized the soil water medium at the pedon, field, and watershed scales. He also designed and evaluated international sustainable water management programs that deal with population growth and water shortage conditions in arid climates. His research has resulted in improved methods for environmental and natural resources engineering, many of which have been adopted by other professionals and agencies internationally. As a member of the World Economic Forum Global Agenda Council on Water Security since 2009, he authored a policy paper on the water-energy-food nexus that was published in Water and Growth: The Ultimate Nexus. Professor Mohtar has published over 200 publications including peer reviewed articles, book chapters, conference proceedings, and microfiches.
