The favorite part of my job is teaching, whether as a mentor, academic advisor, research advisor, or course instructor. I enjoy the constant flow of students in and out of my office or lab as they stop by for advice on a range of issues, both academic and personal. Consistent with this, I am eager to participate in activities that afford me the opportunity for extensive interactions with students (e.g. maintaining a team of research assistants, leading Advising Circles, serving as a Posse Mentor). In addition, I volunteer for committees that are most related to their needs (e.g. Campus Affairs Council, the Committee on Residential Life, and the Student Enrollment and Retention Committee) and engage in large-scale efforts on their behalf (e.g. organizing the Denison-Columbus Alliance). It is worth noting that I consistently make a big effort to engage students from underrepresented groups in various activities including my research program (for which I am the only female faculty member at the institution to have received funding from NIH).
While helping students, I try to demonstrate how they can make their own contributions to the campus community and beyond. For example, I frequently ask students in my classes to apply knowledge and skills in ways that might benefit society. I also incorporate service and/or experiential learning projects into my upper level courses, and I recruit students to engage with the local community by participating in STEM activities that I help to organize in Licking County. In fact, I am deeply engaged in a lot of service work, both on and off campus. For example, I represent the Division of Natural Sciences on the Departmental Report Review Committee at Denison, and I serve as the President of a local non-profit, the Granville Education Foundation. My “service” has become increasingly intertwined with my teaching and research, and takes advantage of my quiet but focused, organized, and positive approach to getting things accomplished. I hope that my efforts, besides serving to inspire and educate, also fosters unlimited compassion for others, in keeping with the mission of Denison.

The discipline of developmental biology focuses on how the genetic material regulates the transition of a fertilized egg into an adult. Like many developmental biologists, I seek to understand the functional consequence of changes in genes and/or their transcriptional regulation (i.e., how they are turned ON and OFF). Such changes can alter the phenotypic outcome of embryogenesis, explaining how differences arise in the course of evolution. For many years, I have used a marine invertebrate, the sea urchin, as a model system to study genes that regulate formation of the larval skeleton, including two genes that are also associated with metastasis in humans. Some of that work was published in a major paper in 2016, the culmination of a grant from the NIH.
Recently, I have also initiated experiments to explore the impact of environmental change on embryogenesis. I am comparing multiple species to determine if some are more vulnerable than others to variation in factors such as temperature, salinity, and pH. Ongoing work with the sea urchin as well as freshwater snails (including two species found in Ebaugh Pond!) suggests that some species are indeed more vulnerable, but for reasons that are not yet clear. In the future, we plan to perform transcriptome profiling to determine how environmental change impacts embryogenesis at a molecular level, which may also give important insight into the more extended process of speciation. Thus, my research is quite interdisciplinary, combining elements of ecology, evolutionary biology, and developmental biology!
As always, undergraduate students are involved in my research program, often accompanying me to professional conferences held throughout the US.
