Dr. Haroon Sahotra is a Professor in the Department of Civil and Environmental Engineering at the University of Nevada, Las Vegas. Dr. Sahotra is involved in interdisciplinary research of climate change impact and hydrology with specific emphasis on applications of remote sensing and geographic information systems (GIS) and specific focus on safeguarding and improving urban quality of life. He has substantial experience in acquisition, processing, visualization, archiving, and utilization of geospatial data. He has been involved in several Federal and State sponsored research projects involving research and applications of geospatial data. In these projects, he has worked with the Bureau of Land Management, Bureau of Reclamation, U.S. Forest Service, City of Las Vegas, Nevada Division of Forestry, Nevada Division of Environmental Protection, and Nevada Department of Transportation. Dr. Sahotra has developed the Visualization Facility at UNLV that provides state-of-the-art visualization of complex datasets and processes for research and educational needs of UNLV and the region. He also provides GIS and Remote Sensing research and training support to UNLV campus. He has participated in various competitive research grants, including National Science Foundation grants titled “The Solar Energy-Water-Environment Nexus in Nevada”, and “Collaborative Research: The Western Consortium for Watershed Analysis, Visualization, and Exploration.” Currently, he is lead PI of a $2.5M National Science Foundation project titled “Enhancing Critical Transitions in Civil Engineering Degree”. Dr. Sahotra's ongoing research interests include applications of remote sensing and GIS technologies to water resource mapping; transportation; and natural and urban climate study. Some active projects include urban heat island mapping; urban flood modeling; regional emission inventory development; and environmental impacts of solar energy farms.
