I specialize in optimal design of power systems with large shares of renewable energy (up to 100%), particularly focusing on the potential for demand-side response to help balance these power systems (e.g., charging electric vehicles automatically during sunny or windy times of day).

I am also the lead author of the Switch power system planning model.

My current curriculum vitae (CV) is available here.

Teaching

I teach EE 435 - Electric Power Systems every fall. More details on this course can be found here.

I teach EE 635 - Smart Grids and Renewable Energy Integration every spring. More details on this course can be found here.
