He has published and presented his research widely, and has received funding from the National Institutes of Health (National Institute of Child Health and Human Development and the National Cancer Institute) and the Robert Wood Johnson Foundation. Dr. Agnew has served on the editorial boards for the Journal of Personality and Social Psychology, Personality and Social Psychology Bulletin, and Personal Relationships (on which he served as Associate Editor).

He served as President of the International Association for Relationship Research in 2011 and 2012. He has been privileged to work with a number of outstanding graduate students as major professor at Purdue, including Tim Loving (University of Texas at Austin), Ben Le (Haverford College), Wind Goodfriend (Buena Vista University), Paul Etcheverry (Southern Illinois University at Carbondale), Justin Lehmiller (Harvard University), Candace Best (Indiana University School of Medicine), Laura VanderDrift (Syracuse University), and Emily Short (U.S. Air Force).  His current students include Ezgi Besikci and Kenneth Tan.  In 2011 he was honored with the creation of the Christopher R. Agnew Research Innovation Award by the Department of Psychology at the University of North Carolina at Chapel Hill, awarded annually to the graduate student enrolled in the Social Psychology Doctoral Program at UNC who demonstrates the most scholarly independence and promise.
