My activity at Shippensburg resides in three main fields, teaching, scholarship, and service. I enjoy teaching most and get to teach a general education environmental biology course, in addition to several majors and an occasional graduate course. I recognize that multiple instructional methods should be used to help the students learn and strive to create meaningful experiential lessons that augment the more teacher-centered times in class. Student engagement is a consistent goal for each of my classes.

Conducting research with students is the bulk of my scholarship. I consider myself a teacher-scholar since almost all of the research questions I ask are in collaboration with students. Collaboration with other faculty is also highly synergistic and while I have collaborated with several faculty in and outside of the biology department, I routinely collaborate with Dr. Lehman and Dr. Fedrow. This greatly enhances our abilities since they approach each hypothesis from a different angle than me. I think it is exceptional for students when they work with collaborating faculty to observe and participate in such thinking and dialog.

Serving the department, university, system, and my discipline is very important. Towards that end, I have been the president of the Commonwealth of Pennsylvania University Biologists (CPUB) and currently am one of the representatives to this organization for our department, serve (or have served) on a variety of university and department groups to better the educational experience of our students.
