PhD Students

Alex Anderson-Connolly
In his research Alex employs Numerical Weather Prediction (NWP) models at high resolutions to investigate alpine micrometeorology. He is particularly interested in slope flows, cold air pools, mountain wake effects, intermittent turbulence as well as improving the numerical methods to study such phenomenon.

Lily Engel
Lily is interested in modeling ecosystems' response to long term climatic change, specifically focusing on the San Francisco Bay. She previously attended the University of Arizona in the Biosystems Engineering and Mathematics departments.

Olivia Hoang
Research focuses on characterizing the stratified tidal dynamics in the San Francisco Bay using observations and theoretical models.

Kimberly Huynh
Research focuses on assessing the fraction of methane release from tropical wetlands attributable to hydrodynamic transport.

Theresa Oehmke
Teri Oehmke is an experimentalist looking to uncover the governing parameters for mass transport in turbulent flow. Time series data of dissolving sugar particles (manufactured in-house) are used to calculate dissolution rates. Understanding of candy science, transport, and turbulence are key topics for this research. Outside of the lab, Teri is involved in aquatic sports such as water polo and swimming. She is also on the comittee for the Empowering Women of Color Conference (2017, 2019).

Jason Simon
Research focuses on modeling the planetary boundary layer in numerical weather prediction and regional climate models.


Liya Weldegebriel
Liya Weldegebriel's PhD work focuses on how multiple catchment management projects (as implemented via watershed development or ecosystem services payment policies) might scale from local to basin-level. The goal is to understand how the marginal benefit of watershed services might vary with increasing investment, with the hope of better informing the design of watershed management projects. Liya is also intrigued by how accounting for multiple criteria (e.g. equity as well as efficiency) might influence the design of such projects. Her efforts focus on a case study in the Lake Tana Basin in Ethiopia. She is currently looking at impact of soil and water conservation practices on stream flow and sediment transport.

Jeannie Wilkening
Jeannie’s research focuses on interactions between water and vegetation in the critical zone. Currently, she is working on developing a coupled model for plant water uptake that combines a stable isotope tracking model with a plant physiology model and conducting supporting field and greenhouse studies. She has also worked on applying simple hydrological models to better understand the drivers and patterns of plant pathogen spread.

David Wiersema
Research focuses on computational fluid dynamics and urban air quality modelling.

Minghui Zhang
Ming tracks the agricultural practices of soybean growers in Brazil in response to climate change through remotely sensed imagery, timeseries analysis, and land use classification. Her research is part of a broader effort to curb deforestation by defining the economic value of natural vegetation to Brazilian agribusiness.
