A Short Bio:


Ardeshir is an assistant professor in the department of civil, environmental, and geo-engineering at the University of Minnesota (U of M) as of September 2016. Prior to joining U of M, he has worked as an assistant professor in the department of civil and environmental engineering at Utah State University for a year and as a postdoctoral research fellow at Georgia Institute of Technology for two years. He received his doctoral degree in civil engineering from Saint Anthony Falls Laboratory at the University of Minnesota (UMN) in 2013, where he also received a master degree in mathematics from the School of Mathematics. In his last year at the University of Minnesota, he served as a NASA Earth and Space Science Fellow (NESSF) and as a University of Minnesota Doctoral Dissertation Fellow (DDF). 

Ardeshir received his B.Sc. in civil engineering from Iran University of Science and Technology (IUST) in 1999, where he also received two M.Sc. degrees in environmental and earthquake engineering. He has worked in industry as a design engineer for a few years prior to the start of his doctoral degree in the United States. 

His research experience includes hydrologic data sciences and inverse problems in hydro-meteorological systems, physical hydrology and land-atmosphere interactions, stochastic hydro-meteorology, and environmental risk and extreme value analysis. In the past few years, his major area of research has been focused on hydrologic remote sensing, data assimilation, and land-atmosphere interactions.
