Ph.D. Students

Belize.jpgBelize A. Lane

Belize is pursuing a Ph.D. in Hydrologic Sciences from the University of California, Davis. Her research interests include sustainable management of basin-level water resources for both humans and the environment, and the integration of hydrology, hydraulics, sediment transport, geomorphology, and riverine ecology in river restoration. Current work includes using water simulation modeling to evaluate the potential to provide environmental flows to regulated rivers through reservoir re-operation. Belize holds a B.S. in Ecology, Behavior and Evolution from the University of California, San Diego. She is also a whitewater rafting guide and has boated on rivers in California, Oregon, Chile, Costa Rica and India. Email:



Jose Pablo Ortiz Partida

Jose Pablo received a scholarship from the Mexican Government for pursuing a Ph.D. in Hydrologic Sciences at the University of California, Davis. He is interested on Integrated Water Resources Management with an specific focus on water quantity and water quality modelling. He earned his Bachelor’s degree in Environmental Engineering from the Western Institute of Technology and Higher Education (ITESO) in Guadalajara, Jalisco, Mexico. He is working on a water quality modeling for the Big Bend reach of the Rio Grande/Rio Bravo Basin. His dream is to find solutions for the preservation and distribution of water resources to provide people in need access to clean and safe water. Email:


Alyssa DeVincentis

Alyssa is pursuing a Ph.D in Hydrologic Sciences from the University of California, Davis and is a trainee in the Climate Change, Water and Society IGERT program. Her research interests include agricultural groundwater management and integrating societal response to climate change into hydrologic modeling. She holds a B.S. in Environmental Science from Rutgers University where she researched the economics of recycling water at horticultural operations throughout New Jersey.  She served in AmeriCorps for a year in Texas before coming to UC Davis.


jenna-rodriguez.jpgJenna Marie Rodriguez

Jenna is currently a tenured National Science Foundation (NSF) fellow under the Graduate Research Fellowship Program (GRFP) and works at the Center for Spatial Technologies and Remote Sensing (CSTARS) at UC Davis.  She is pursuing a PhD in Hydrologic Sciences at UC Davis, and is conducting analysis on remotely sensed methods of evapotranspiration (ET) and assessing agricultural water consumption among arid and semi-arid regions.  Remotely sensed methods of water consumption include spectral indices and energy balance algorithms.  Specifically, this project includes collaborators from University de Concepcion, Chile, University of Arizona and CSIRO - Caberra to include dryland regions of United States, Chile, Southern Australia and Spain.  Jenna currently holds a B.S. in Environmental Sciences from UCLA, and is completing her M.S. in Hydrologic Sciences from UC Davis.  She was recently awarded the first Kenneth K. Tanji for distinguished public service and the W.D. Farr Fellowship Award from the National Cattleman's Foundation for leadership and dedication to agricultural water management. Email:

 Sooyeon Yi


Sooyeon is pursuing a Master of Sciences degree in Hydrologic Science from the University of California Davis. Her research interest include hydrology, water resources planning and management, focusing on surface water hydrology, reservoir operations, and balanced human and environmental water management. She is using a coupled Hydrologic and water planning platform [Water Evaluation and Planning (WEAP)] to simulate the water availability and water supply in the Apurimac River Basin, in Peru. She has been evaluating average conditions (synthetic) and historic climate to determine the sensitivity of the model to the various parameters involved. Once the model is calibrated, it will be used to test current and future water demands that include a reservoir. The outcome of the study will provide guidance for stakeholders (Peru and Arequipa Regional Government) to decide whether to or not to build reservoir and their impacts to anthropogenic and environmental water requirements.

Pablo Tomas Silva Jordan

Pablo is pursuing a Master's degree in Hydrologic Sciences at University of California, Davis. His interest focuses on water resources management, his research combine water supply, distribution and management at basin and sub-basin scales. He comes from Chile motivated by the similarities that California has with the central region of Chile in terms of geography, climate, land use, economic activities; and the strong influence that UC Davis has on the agricultural sector in Chile. He obtained a bachelor degree in Civil Engineering at Pontificia Universidad Catolica de Chile. After that, he worked on an irrigation consultant company in Chile for four years. He is also an outdoor sport fan, practicing mountain bike, hiking and mountain climbing. Email:



Bruno R. Britos

Bruno is pursuing a Master’s degree in Hydrological Sciences with a focus on Water Resources Management at University of California, Davis. He earned a degree in Civil Engineering with a Specialization in Water Resources at National University of San Juan and an MBA at Catholic University of Cuyo, both in Argentina. Due to the similarities between San Juan and California in terms of weather conditions, use of land and scarcity of the water resources, he decided to come to UC Davis seeking the latest science and state-of- the-art techniques in hydrological sciences. His aim is to help water managers, users and stakeholders to make better decisions regarding the allocation, management and best uses of such a vital resource as water is for life. He expects to achieve this challenge by doing research and applying his vast professional background through a holistic approach. In his free time he enjoys listening to Rock & Roll music and loves playing the drum. Email:


Maritza Flores Marquez

Maritza Flores Marquez is pursuing a Master’s degree in Civil and Environmental Engineering with an emphasis in Water Resources Engineering at the University of California, Davis. Her research interests focus on groundwater, water resources management, and water quality. Maritza obtained a Bachelor’s degree in Environmental Engineering with a minor in Public Health from the University of California, Merced. Motivated by California’s pressing water issues, specifically within the Central Valley, she strives to broaden her skills and knowledge with regards to water management.  Email:



Kelly Kane

Kelly is working towards a Master of Science in Ecology with an emphasis in restoration. She obtained her undergraduate degree from Cal Poly San Luis Obipso in Environmental Management and Protection and has since worked at a number of agencies and private companies, primarily conducting salmonid population monitoring as well as biological and compliance monitoring for construction projects. Kelly’s interests in water resource assessment related to environmental flows motivated her to return to school for graduate studies. Her thesis work involves improving time step feedback between the Water Evaluation and Planning (WEAP) modeling system and a fish habitat suitability model that focuses on spring-run Chinook salmon in Butte Creek, CA.
