Dr. Hanigan graduated from the University of Missouri - Columbia with a B.S. in Civil Engineering in 2009. He was awarded an M.S. in 2011 from the University of Missouri where his research focused on the removal of Trihalomethane (THM) and Haloacetic acid (HAA) precursors using MIEX and activated carbon.

During his M.S., Dr. Hanigan was awarded the Paul Kufrin Memorial Scholarship. While working towards his Ph.D. he has received multiple awards, including the Ira A. Fulton Fellowship, ACS Graduate Student Award in Environmental Chemistry, ASU Engineering Dean's Fellowship, and AZ Water Association Scholarship. Hanigan's Ph.D. was further supported in part by the prestigious AWWA Abel Wolman Fellowship and the WEF Canham Graduate Studies Scholarship.

His Ph.D. research (2015, Arizona State University) focused on removal, characterization, and identification of N-nitrosamine precursors. His current research interest is in how anthropogenic chemicals (pharmaceuticals, pesticides, etc.) affect human health and ecological endpoints.

After completion of his Ph.D. he was a post-doctoral researcher at Arizona State University studying the implications of nanomaterial use through their life cycle (EPA -LCNano).

Research interests

Increasing global population has amplified anthropogenic loading of organic matter to the water cycle, and increased the rate of incidental water reuse, both of which are core concepts of Hanigan's work. The Hanigan Lab focuses on environmental organic and inorganic chemistry and process based water treatment.
