Trenton Franz, Ph.D.
Trenton's interests were in the processes that influence dryland ecosystem’s vegetation patterns. The main focus of his PhD was on the dryland ecosystem of central Kenya. In addition to extensive field campaigns using geophysical techniques to understand near surface soil moisture dynamics, Trenton developed numerical models to study the ecosystem water balance at the regional and hillslope spatial scales. Utilizing a resource tradeoff hypothesis for dryland vegetation organization, complex problems, such as the optimal spatial pattern of vegetation, can be made into tractable optimization problems.
Benjamin Court, Ph.D. - Email
Ben's research focused on two critical aspects of CO2 sequestration: the previously identified issue of CO2 sequestration safety, and the newly identified issue of water management coupled to carbon capture and sequestration operations.
Dissertation: Court, B. 2011, Safety and Water Challenges in CCS: Modeling Studies to Quantify CO2 and Brine Leakage Risk and Evaluate Promising Synergies for Active and Integrated Water Management, Ph.D. Dissertation, Princeton University.
Juan Nogues, Ph.D.
For my PhD research, I investigated appropriate upscaled relationships that can be used to model two-phase flow in geological formations with specific applications to geological carbon sequestration. These relationships take the form of upscaled capillary pressure and relative permeability curves, functional representations of mass transfer across phases that are dependent on dimensionless variables, and permeability-porosity relationships that arise from upscaling pore-scale flow dynamics and geochemistry. I also completed a certificate at the Woodrow Wilson School in Public Policy, where my research focused on how regulations should be designed to address the inherent uncertainty of leakage of CO2 from geological sequestration operations. That study looked specifically at the design of a monitoring well scheme to detect leakage of CO2. I am currently a faculty member at the Universidad Nacional de Asuncion in Paraguay.
Adam Janzen, MSE
Adam's thesis, entitled "Development and Application of a Multi-Scale, Multi-Layer Numerical Model for CO2 Injection", described a new subscale analytical correction for calculating pressures at injection wells and investigated the effects of diffuse brine flows through low-permeability confining layers on the pressure response of a multi-layered system. Adam received his B.S. in Civil and Environmental Engineering from the University of Illinois at Urbana-Champaign in 2008. Earlier this spring he earned local bragging rights in Princeton by winning the 30th Annual Longbeard Contest at the Alchemist and Barrister.

James Wang, MSc
James developed a software framework in MATLAB using an adaptive Markov Chain Monte Carlo sampler to automate parameter estimation from Vertical Interference Test pressure profiles. He received a B.S. in Chemical Engineering and a minor in Applied Microeconomics from Washington University. James spent a summer interning with Procter & Gamble and another summer researching air pollution at Tsinghua University and with MIRTHE. He grew up in Princeton Junction and enjoys playing tennis, ultimate frisbee, and snowboarding.
