Associate Professor


Mechanical Engineering


  • 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 – Fundamental principles of granular materials such as 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.
  • Biomass Energy – Material handling and utilization for local energy conversion
  • 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.
