He was promoted to associate professor in 2001.  From the period of 2008 to 2010, he served as the Assistant Chair for Undergraduate Affairs for the department. His research area is primarily involved with biological wastewater treatment systems and is focused on three general areas:  respirometric evaluation and modeling of biodegradation; anaerobic treatment of agricultural, industrial, and municipal wastes; and a newly patented high rate anaerobic system, termed the static granular bed reactor (SGBR) for renewable energy production.

Dr. Ellis has secured research contracts as a sole principal investigator valued at $1.5M and collaborated on research projects valued at an additional $1.8M.  He has published more than 40 peer-reviewed papers and given more than 60 technical presentations at national and international conferences. His publications have been cited more than 300 times in the scientific literature, and he is the 16th most cited author in Water Environment Research. In 2013 he was named the Outstanding Government Civil Engineering by the Iowa Section of the American Society of Civil Engineers.  He has received numerous departmental and engineering college awards at Iowa State, including the Outstanding Faculty Award (2008, 2002, and 2001); the Anderlik Faculty Award for excellence in undergraduate teaching (2005); Outstanding Advisor Recognition Award (2002); the Shafer Award for excellence in teaching, research, and service (1999); and Leadership through Academic Diversity Faculty Involvement Award (1999).
