Jay Famiglietti
Director and Professor 
Earth System Science, Civil and Environmental Engineering
240K Rowland Hall, Irvine, CA 92697-4690

Professor James S. Famiglietti holds a joint faculty appointment in Earth System Science and in Civil and Environmental Engineering at the University of California, Irvine, where he is the Founding Director of the UC Center for Hydrologic Modeling. His research group uses satellite remote sensing to track water availability and groundwater depletion on land, and has been working for many years towards improving hydrological prediction in regional and global weather and climate models. Before joining the faculty at UCI in 2001, Dr. Famiglietti was an Assistant and Associate Professor in the Department of Geological Sciences at the University of Texas at Austin, and was the Founding Associate Director of the UT Environmental Science Institute. He is the past Chair of the Board of the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI), and the past Editor-in-Chief of Geophysical Research Letters. Famiglietti is currently leading the Community Hydrologic Modeling Project (CHyMP) effort in the United States to accelerate the development of hydrological models for use in addressing international priorities related to water, food, economic, climate, and global security. In 2012 he will serve as the Birdsall-Dreiss Distinguished Lecturer of the Geological Society of America, when he will lecture internationally on global water cycle change and freshwater availability.

Neeta Bijoor
Postdoctoral Scholar
240E Rowland Hall, Irvine, CA 92697-4690

Neeta is a Postdoctoral Scholar at the UC Center for Hydrologic Modeling. Her research interest is urban hydrology, including the fate of applied irrigation water, evapotranspiration, distinguishing transpiration losses from evaporation, and understanding the water sources of urban plants. To reduce these uncertainties for urban ecosystems in Southern California, she makes a variety of measurements including flux chamber measurements of ET, the isotopic composition of plant, soil, water and atmospheric vapor, as well as soil moisture, irrigation and runoff. Her research explores potential methods for reducing water use in urban ecosystems in response to future climate change and water scarcity.

Callie Brazil
Associate Producer

Callie is responsible for communications, education and outreach efforts for the UCCHM. Specifically, she manages the production of editorial content for multiple websites and blogs, monitors and updates the Center's social media networks and supports a wide range of events and outreach campaigns showcasing UCCHM research. Callie earned her BA in Environmental Biology from Colgate University, where the importance of a holistic approach to sustainability became a guiding principle for her. Ultimately, Callie is interested in breaking down scientific research findings and "translating" them in order to make the information publicly accessible and relevant.


Stephanie Castle
Data Specialist, Education and Outreach
240X Rowland Hall, Irvine, CA 92697-4690

Stephanie graduated from UC Irvine in June 2009 with a BS in Earth System Science which guided her towards remote sensing and hydrology. Since working for the Center, she has performed research on the GRACE mission, its processing centers and the different methods of producing hydrology products. She has also found a passion in water policy after her experience of planning two UCCHM events titled “Working Towards Sustainable Water Solutions to Support Central Valley Farmers” in August 2010 and “The Bridge: A Forum for  Exchange between Water Researchers and Environmental Decision Makers” in April 2010. Right now she is working on a new data interface for UCCHM affiliates which will enable them to easily search for hydrologic data as well as a developed water balance for California. She will start a Masters in Urban and Regional Planning in September 2011 at UC Irvine and she looks forward to learning more about water use, management, and policy.


Cédric H. David
Project Scientist
240F Rowland Hall, Irvine, CA 92697-4690

Cédric is interested in the terrestrial water cycle at the continental scale with particular focus on river flow within large networks. His areas of expertise include Hydrologic Modeling, High-Performance Scientific Computing, Geographic Information Systems, etc. Two overarching questions currently motivate Cédric’s research:

  1. How does water flow on the land surface?
  2. How can we best account for the influence humans have on surface water in current modeling approaches?

Cédric joined the UC Center for Hydrologic Modeling in October 2012. Prior to that, he spent three years (2009-2012) as a Postdoctoral Fellow in the Department of Geological Sciences at the University of Texas at Austin. Cédric holds a Master of Science in General Engineering from Ecole Centrale de Lille (2004), a Master of Science in Environmental and Water Resources Engineering from the University of Texas at Austin (2006), and a PhD in Civil Engineering from the University of Texas at Austin (2009).

Michelle Miro
Graduate Fellow
240N Rowland Hall, Irvine, CA 92697-4690

Michelle Miro is a Ph.D. student at the University of California, Irvine studying Hydrology and Water Resources in the Department of Civil and Environmental Engineering. Her current work utilizes observations from the GRACE satellite system to develop methods to better estimate local-scale groundwater availability and inform regional water management decisions in the Jordan River Basin. Overall, she seeks to link water resources policy and planning with interdisciplinary and hydrologic research, particularly for water-stressed and developing regions. Michelle holds an M.S. in Civil Engineering from the University of Illinois at Urbana-Champaign, where she specialized in Environmental Hydrology and Hydraulic Engineering. Her research used an agent-based model to study the impacts of irrigation and water management decisions on regional hydrology in the Republican River Basin. She received her B.A. in Health and Policy in the Developing World from the University of Texas at Austin, where she focused on water provision and planning in Tamil Nadu, India. Michelle is currently an NSF Graduate Research Fellow and a U.S. Borlaug Fellow in Global Food Security.

JT Reager
Postdoctoral Scholar
240D Rowland Hall, Irvine, CA 92697-4690

JT became a Postdoc at UCCHM after receiving his PhD in Earth System Science in 2012. He is working with data from NASA's GRACE mission to answer questions about global hydrology and climate, and to improve the representation of hydrological processes in global land-surface models. His work includes a gravity-based flood prediction methodology and a characterization of typical water storage behavior for the world's largest river basins.

Sasha Richey
Graduate Fellow
240V Rowland Hall, Irvine, CA 92697-4690

Sasha Richey is a PhD student in the Hydrology & Water Resources program within Civil & Environmental Engineering at UC Irvine. She is an overly proud Seattlite who received her Bachelor’s of Science in Civil & Environmental Engineering with an Environmental and Water Studies specialty at Stanford University. Sasha’s childhood in watery Seattle, with parents who also study water, sparked her interest in hydrology at an early age. Her dissertation research works to improve global estimates of water stress, with a focus on groundwater. She uses observations from the GRACE satellite mission to better quantify human water use as compared to water availability. Ultimately, Sasha is interested in the intersection of science and policy, with a goal of using her research to inform science-based sustainable groundwater management strategies. Sasha is also a member of CLEAN Education, a student group at UC Irvine that teaches climate science lessons to local K-12 schools, with a focus on global change. In her spare time, Sasha can be found biking, cooking, traveling, and trying to improve her green thumb in the community garden.

At UCCHM, Kate connects the group’s hydrological research to broader water policy and management implications. As a 2009 NSF REU fellow she developed a global groundwater scarcity index. Since then, Kate researched the political, economic, and social implications of global water trends seen by the GRACE satellite system, and completed case studies for northwest Australia, the Tigris-Euphrates River Basin, and China. In addition to her research at UCCHM, Kate conducted field work looking at the connection between the environment and development in northeast Thailand; and during Spring 2011, worked with Aqueduct, the water-risk team at World Resources Institute.
