Meet our current dissertators!
Dissertators are PhD students who have completed their preliminary exams – – the last big hurdle before their final defenses. These students have completed all of their required coursework and can fully concentrate on completing their research projects. Along with the other WEMPEC students, all of these dissertators will be presenting their work at the Poster Sessions during our Annual Review in May. We hope that you’ll attend, talk with these students, and perhaps even learn something from these future leaders in the field of power engineering!

Anvar Khamitov Prof. Eric Severson Anvar develops an analytic winding design theory as well as a new and exact model for bearingless machines, and exact actuation of multiple airgap magnetic field space harmonics for precise regulation of magnetic forces on the shaft. |
Nathan Petersen Prof. Eric Severson Nathan’s research focuses on developing accurate models and sensorless control methods for bearingless motors with combined torque and force windings. |
David Skrovanek Prof. Daniel Ludois David’s PhD work investigates a novel way of harvesting ocean wave energy using a generator based on a variable capacitor incorporating the ocean water itself as part of the capacitor. |
