  • Ph.D., Environmental Engineering, Purdue University
  • M.S., Purdue University
  • B.S., Civil Engineering, Purdue University

Research Interests

My research has focused on the fundamental science and engineering supporting the advancement of technologies and practices which have been transformational for environmental engineering. These have included topics such as wastewater nutrient removal and recovery (biological and chemical), treatment process optimization and control (particularly biological treatment systems), control of activated sludge bulking and foaming, which can be debilitating and lead to excessive treatment costs if not properly addressed and the highly efficient coupled, attached and suspended growth systems.
