**University of California-Berkeley, Department of Nuclear Engineering**
**Doctoral candidate**
The dissertation thesis focused on the mathematical modeling of mass transport in the engineered barrier system of a high-level nuclear waste repository. A mass transport model was established for radionuclides in a porous medium, bentonite extrusion model in a planar fracture to assess the potential to confine radionuclides.

# Related research experience
**Earth Sciences Division, Lawrence Berkeley National Laboratory**
**Intern**
Conducted data analysis for chaotic modeling of water flow in the unsaturated zone.
*2001-02*
**Leslie C. Wilbur Nuclear Reactor Facility, Worcester Polytechnic Institute**
**Major Qualifying Project**
The Major Qualifying Project synthesizes previous undergraduate studies to solve problems or perform tasks in the major field and communicate results effectively. For this project, a logic algorithm was developed for reactivity derived from point kinetics equations and a programmable logic controller was modified for real time collection of data during nuclear reactor operation for use with experimental coursework and maintenance procedures.
