Dr. Aliasghar Montazar joined UCCE on June 1, 2017 as an Irrigation and Water Management Advisor. Prior to joining UCCE, Montazar was working as a Project Scientist in the Department of Plant Sciences at UC Davis since June 2014. From 2011 to 2014, he was a Research Associate in the Department of Land, Air and Water Resources (LAWR), UC Davis. He was formerly associate professor at the Department of Irrigation and Drainage Engineering, University of Tehran, Iran. Montazar has more than 15 years of research, extension, teaching, and technical consulting experience and has served in several leadership positions in agricultural water management and irrigation engineering in California and abroad.


Irrigation and water management, measurement and modeling of surface energy balance variables/ET and crop coefficients, irrigation scheduling, drainage and water quality, on-farm irrigation system management and evaluation, salinity management and control practices, deficit irrigation, environmental instrumentation and modelling.
