New Project PRDG
This project focuses on understanding how viruses use metabolism to successfully produce more virus. The herpesvirus human cytomegalovirus (HCMV) causes severe disease in people with weakened immune systems. Some people develop CMV-related disease in the retina of the eye that can lead to blindness. We do not fully understand how this disease progresses or the metabolic changes in the retina during infection. Retinal organoids are multicellular models that mimic retinal tissue in the eye. The project will develop a retinal organoid model of HCMV infection that will be used to study how the virus spreads, changes metabolism, and contributes to disease in the retina.

Bio
Dr. Rashi Bhushan is a Postdoctoral Research Associate at the University of Arizona, focusing on achieving Net Zero Urban Water (NZUW) futures in the U.S. Southwest amid challenges like the Colorado River crisis. Dr. Bhushan earned her Ph.D. from the Hong Kong University of Science and Technology and M.S. from the Pennsylvania State University, both in Civil Engineering. Prior to her Ph.D., she worked with an environmental consulting firm, focusing on hydrologic and hydraulic modeling for FEMA floodplain development. Her research interests include hydrologic modeling, adaptive water resources management, systems analysis, and multi-objective optimization.
New Project PRDG
Tucson’s Active Management Area faces declining groundwater levels and reduced Colorado River allocations. Existing recharge projects rely on treated wastewater and imported surface water, leaving urban stormwater untapped. The Flood Control District has identified locations for recharge using detention basins and dry wells, but the amount of stormwater reaching the aquifer is uncertain. With support from the Postdoctoral Research Development Grant, this project will use HYDRUS‑2D to model stormwater infiltration through these structures, considering local soils, geology, and subsurface variability. The model aims to offer accurate recharge assessments for effective stormwater projects in arid regions.
