Resume (for consulting jobs)  •   CV (for academic jobs)  •   Linkedin Profile  •   Research Gate Page


I'm working as a postdoc for Cornell University, but I live in the Bay Area and am looking for a job here for this coming fall (2017). My background is in hydrodynamic modeling, and I would like to continue in this field, either in academia or as a consultant. I specialize in 3D modeling of lakes, flow through aquatic vegetation, and plumes. My current position combines consulting with academic research. I'm passionate about teaching and have considerable teaching experience but may take a break and revisit education later in my career, depending on the opportunities that present themselves.

Current Position (June 2011 - present)

As a postdoc in the Department of Civil & Environmental Engineering, I am providing consulting services to Cornell University in the New York State Department of Environmental Conservation (DEC) permit renewal process for Cornell's Lake Source Cooling (LSC) facility. LSC is an award-winning sustainability project that replaced Cornell's traditional air conditioning system with cooling from lake water. The DEC is concerned that the LSC system pumps a small amount of phosphorus from the bottom of the lake, where it is dormant during the summer, onto the shallow southern shelf, where it is available to algae. 

I am developing a 3D hydrodynamic model for Cayuga Lake to measure the effect of the LSC outfall, an active point source discharge, on water residence time within the southern shelf. I have developed a sub-model for entrainment of active point sources within the existing 3D hydrodynamic solver Si3D. I designed and led field studies to calibrate the model and used existing data sets for validation. DEC also asked Cornell to evaluate the viability of an extended deep-water outfall, and I conducted this evaluation using the CORMIX modeling package. 

I have mentored several undergraduate and master's students, and in 2013 I served as scientific program coordinator for Cornell's CURIE Academy, a week-long summer program for high school women interested in science and engineering.

Course Notes 

I developed these course notes for Cornell's CEE 6550 - Mixing, Transport, and Transformation in the Environment. They are currently used by professors and other instructors at Cornell, Berkeley, and UIUC. The notes are an elaboration of Fischer et. al. (1979) at a level more accessible to first year graduate students and seniors. They also draw material from Professor Heidi Nepf's course notesSue-Nee Tan, a Cornell graduate student, provided the figures. Following the style of Fischer et. al., the focus is on physical processes, and mathematical techniques are developed in support of understanding and applying physics. These notes are available for anyone to use provided that the contributors are credited. I will provide the original LaTeX files upon request.
