Biography

Gregory Okin is a Professor at the Institute of the Environment and Sustainability at UCLA, currently serving as Chair of the Department of Geography. He received his PhD in Geochemistry from the California Institute of Technology in 2001. His research interests are primarily focused on plant-soil-atmosphere interactions in the world's drylands, which cover 40% of the Earth's land surface. A significant aspect of his work involves understanding how atmospheric dust, mainly from drylands, affects mineral aerosols. His research combines laboratory, field, and modeling efforts and employs remote sensing analysis to study various processes. One active project investigates the impacts of wind erosion that drives the conversion of grasslands to shrublands, a phenomenon observed in drylands globally. Additionally, he is exploring cloud computing technologies to monitor rangeland conditions by combining satellite and field data.
