Education
- Ph.D. in Mechanical Engineering, Northwestern University, 2006
- S.M. in Aeronautics and Astronautics, Massachusetts Institute of Technology, 2002
- B.S. in Mechanical Engineering, University of Dayton, 2000
Research Interests
- Granular Flows – Exploring fundamental principles of granular materials to characterize fluid mechanic-like properties (e.g. boundary flow effects, energy loss in transportation devices, transient dynamics from unsteady forcing).
- Energy Optimization – Evaluating and designing mechanical systems and operational methods for optimal consumption and generation of total energy.
- Estimation and Control – Create experimental systems with appropriate sensors for robust evaluation of state in order to conduct responsive, real-time control.
- Multi-phase Fluid Dynamics – Determining the changes in flow velocity profiles as related to phase concentration and mixing/separation of phases due to flow field.
