of Florida in Gainesville, FL, where he received his Ph.D. in civil/environmental
engineering and has remained a loyal Gator fan ever since, serving as a Bull Gator and
on the President’s Council. He was an associate professor in the Civil Environmental
Engineering Department at Michigan State University prior to entering the consulting
field. Many of Dr. Cornwell’s students now are active members of the water profession. During his career as a consultant, Dr. Cornwell has provided process, design, and
operational troubleshooting services to water utilities around the world. He has lectured
and written on many aspects of water treatment, including over 50 peer-reviewed
technical articles and reports. Much of his work has included the development of new
and optimized water treatment processes. He has won three JAWWA Division best
paper awards and the overall JAWWA publication award. Dr. Cornwell has an extensive
record of service to the water profession. He has been an active member of American
Water Works Association (AWWA) since the early 1970s and has served on numerous
committees in that organization. He has chaired the Research Division and the Technical
and Education Council, and served on the board of directors and executive committee
of AWWA. In 2005, Dr. Cornwell was the recipient of the A.P. Black Research Award given
by AWWA to recognize excellence in water treatment research, recognizing his contributions
to bridging the gap between research and application. Dr. Cornwell has been a
principal investigator on over 20 Water Research Foundation research projects. |
