I joined ASU in 1995 as an environmental engineer and am part of the Ira A. Fulton School of Engineering in the recently formed School of Sustainable Engineering and The Built Environment at Arizona State University- ASU. I have served as the Department Chair and School Director, and now focus on teaching (ASU101, CEE 361, 462, 561, 563, 567 and 598) and research in the area of emerging contaminants and innovative treatment processes for clean water.  My RESUME is available: A long RESUME-2019. My research group has over 270 peer reviewed journal publications and an H-index >70. My current research interests include:

  • Innovative treatment processes using nanotechnology
  • Sources and characterization of natural organic matter (NOM) in natural systems
  • Formation of disinfection by-products (DBPs) during water treatment
  • Detection and exposure assessment to engineered NANOMATERIALS in the environment
  • Removal of arsenic and metals from drinking water
  • Control and treatment of alga-derived taste and odors (T&O) in potable water supplies
  • Indirect reuse of treated wastewater
  • Recharge of aquifers with surface water
  • Use of photosynthetic microalga for controlling green house gases (CO2)
  • Management and treatment of nitrate (NO3) in drinking water supplies

My research is focuses water issues involving Arizona, but these tend to address many global challenges as well. This research leads to a number of multidisciplinary research activities with biologists, botanists, chemists, and geologists. Recently completed and ongoing projects can be viewed for project summaries. Below are some links to multidisciplinary centers that I interact with:

Undergraduate and graduate (master and Ph.D.) students and post-doctoral researchers are involved in funded research from local and national agencies (see research interests). Information of my current research group are available here.

I am married to Kelly and have a daughter and twin sons.
