Research Interests

I’m interested in physical processes impacting ecosystem dynamics in natural water bodies. For my dissertation, I developed a model for flow through aquatic vegetation that predicts velocity profiles and vertical fluxes (e.g. of nutrients, dissolved gasses, and sediment) from plant geometry. I’m also interested in lake-scale hydrodynamic models. As a postdoc I developed a method for quantifying flow and entrainment of cooling water effluent within a three-dimensional hydrodynamic model in order to investigate the impact of a cooling water outfall on residence time of Cayuga Lake's shallow southern shelf. I am currently developing a two-dimensional hydrodynamic/water quality model of Honeoye Lake to investigate the physical and chemical processes delivering Phosphorus to cyanobacteria. 

Teaching Interests

Fluid mechanics, mixing and transport processes, computational fluid mechanics. I have taught as a teaching assistant and as an instructor for undergraduate and graduate courses of 17-120 students.

Course Notes 

I developed these course notes for Cornell's CEE 6550 - Mixing, Transport, and Transformation in the Environment. They 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.
