Academic Experience

Doctoral Thesis: Estimation with Applications for Vehicle Dead Reckoning and Control, 00-03

·         Developed an extremely precise tire parameter estimation scheme for real vehicles.  Did so using nonlinear estimation theory and numerical computing methods. Demonstrated precision experimentally on two different types of tires.  Patent pending and Collegiate Inventors Competition Finalist in 2003.

·         Developed a vehicle dead reckoning system using GPS and stock wheel sensors.  Showed that contrary to previous work on the topic, quantization error and wheel slip are not dominating factors for this system.  Road surface unevenness is the primary error source.

·         Developed a nonlinear vehicle control structure using Model Predictive Control.  Demonstrated control structure as an active rollover prevention system for automobiles.

 

Design Division Student Representative, 02-03

·         Year long volunteer position responsible for organizing faculty-student events as well as providing a face to face vehicle for students to express their opinions to faculty

 

Teaching Assistant: System Identification of Mechanical Systems for Control 02-03

·         Maintained and developed fun laboratory systems for identification and control.  Also responsible for evaluation and feedback of student performance.  Course received highest teaching evaluation review to date.

 

Teaching Assistant: Team Based Design with Corporate Sponsorship 99-00

·         Acted primarily as a technical and team relationship consultant for several design teams for one academic year.  Also responsible for student evaluation and project feedback.
