Group Members

Ian C. Bourg, Assistant Professor (CV)

Ian's research examines the properties of interfacial water in natural systems, 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.

Ayumi Koishi, Postdoctoral Scholar

Ayumi's research uses lab-, synchrotron/neutron-, and simulation-based techniques to understand interfacial energetics, nucleation processes, and the dynamics of amorphous phases. She received her PhD in Earth Sciences from the University of Grenoble, France.

Bastien Wild, Postdoctoral Scholar

Bastien's research uses atomistic simulations, laboratory experiments, and surface-sensitive synchrotron techniques to examine the fundamental geochemical and transport processes associated with the durability of silicate materials. He holds a PhD in Earth Sciences from the University of Strasbourg.

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.

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 examines the wettability of mineral surfaces by water, CO2, and soil organic matter in the context of geologic carbon sequestration and soil carbon storage.

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 uses atomistic-level simulations to reveal the fundamental details of clay swelling and its dependence on aqueous chemistry conditions.

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. His research uses computational fluid dynamics simulations and microfluidic experiments to understand fluid flow in deformable porous media such as fine-grained soils and sedimentary rocks.

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. Her interests include the influence of mineral surfaces on the nucleation and growth of gas hydrate clathrates.

Lingru (Lynn) Zheng, Visiting PhD student

Lynn is currently a second year PhD student in Chemical Engineering at Imperial College London. She joins the group as a visiting PhD student for three months. At Princeton, her focus is on understanding the influence of electrolytes on the thickness of adsorbed water films on clay mineral surfaces.
