I joined the faculty of Austin College in 2011, and I am the primary instructor within the psychology department for classes focusing on development across the life course. In addition to my regular courses listed on this page, past C/I and JanTerm courses have addressed such topics as Adolescent Popularity and Adolescence in Film. I have advised and supervised several independent study and thesis students, generally on student-directed research topics that fit within my broad area of expertise; many of these students have presented their work at the Austin College Student Scholarship Conference and at the annual conference of the Southwestern Psychological Association.
Beyond my direct work with students, I am a member of the Austin College Institutional Review Board (IRB) and chair of the Psychology Department as of fall 2018.
Teaching and working with students is a lifelong passion of mine, and I am dedicated to the principles of liberal arts education. I am a regular and active participant in Johnson Center discussions and programs, in which Austin College faculty discuss best practices for teaching, advising, and relating to students within a liberal arts environment. I have also received a Mellon Course Partnership grant to collaborate with a member of the media studies department, Dr. Erin Copple Smith, as part of my seminar on Parent, Peer, and Media Socialization Across the Life-Span. This collaboration with Dr. Copple Smith has been immensely rewarding for both myself and my students, and embodies a central tenet of the liberal arts experience—that students learn best when multiple disciplines and perspectives can be brought together to address academic topics.

My primary research area is in child and adolescent peer relationships, particularly adolescent status and popularity. I want to know what popularity is, why it is so important to adolescents, and how it affects adolescent thinking and behavior. As part of my interest in popularity and peers, I have been involved in research analyzing aggression, physical attractiveness, friendship, and academic achievement. More recently, my published research has been focused on methodology, measurement, and analysis of peer relationships and interpersonal behavior, with a goal of improving the quality of future investigations.
