Broadly, my interests involve system identification (SysID) applied to biological systems, especially:

  • developing methods of SyID,
  • applying methods of SysID to understand biological processes, and
  • advancing methods for teaching SysID (pedagogy).

By system identification, I mean using statistics, derived from experimental data, to constrain models of the system.

System Identification of Cooperative Control

Control Theory Where Agent(s) Rely on Noisy Clocks

Pedagogy for System Identification

I am interested in finding effective methods for training students in the art of system identification. One advantage of system identification over other laboratory techniques stems from the fact that one can collect data to be used in SysID from simulations. In this way students can design and execute many interesting computer based experiments without a large investment in laboratory techniques and training.
