Group Members

Ian C. Bourg, Assistant Professor (CV)

Ian's research examines the properties of interfacial water in porous media, particularly clay-rich soils and sedimentary environments. He holds a BEng in Chemical Engineering from the National Institute of Applied Sciences in Toulouse and a PhD in Civil and Environmental Engineering from UC Berkeley.

Tom Underwood, Postdoctoral Scholar

Tom's research examines the nanogeochemistry of water and ions near clay mineral surfaces. His current focus is the impact of clay aggregation and swelling on the microstructure, mechanics, and transport properties of clay-water mixtures. He received his PhD in Earth Sciences from Durham University in Durham, UK.

Jennifer Willemsen, PhD student

Jennifer joined Princeton as a PhD student in Fall 2015 after graduating from Haverford College with a BS in Chemistry. She is interested in the geochemical interactions between emerging organic contaminants and clay minerals. Her research combines experimental work and molecular dynamics simulations. Jennifer's research is supported by the Princeton Environmental Institute through the Water and the Environment Challenge.

Emily Wei-Hsin Sun, PhD student

Emily joined Princeton as a PhD student in Fall 2016 after graduating from McGill University with a BS in Chemistry. Emily's research is supported by the Princeton Environmental Institute through the Carbon Mitigation Initiative.

Xinyi Shen, PhD student

Xinyi joined Princeton as a PhD student in Fall 2016 after graduating from Peking University with a BEng in Energy and Resources Engineering and a BS in Computer Science. Xinyi's research is supported by the US DOE Office of Science through the Basic Energy Sciences (BES) Geosciences Program.

Francisco Carrillo, PhD student

Francisco was raised in both Costa Rica and Mexico. He has a BS in Chemical Engineering from the University of Texas at Austin and is now working towards a PhD in the same field. He has a background in electrochemistry and microfluidics. Francisco's research is supported by the US DOE Office of Science through the Center for Nanoscale Controls on Geologic CO2.

Mihiro Nomura, MSE student

Mihiro joined Princeton as a MSE student in Fall 2017. She holds a BA in Environmental Sciences from the University of Tokyo. She was born and raised in Japan, Hong Kong, and the U.K. She is interested in the adsorption of contaminants by clay minerals.
