Denison University’s 178th Commencement took place on Saturday, May 18. Watch the ceremony in its entirety including commencement keynote speaker Jennifer Garner ’94.
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.

Transcription is regulated by non-coding sequences known as cis-regulatory elements that are usually located upstream of the protein-coding sequence but may be located downstream of the protein-coding sequence or even within an intron. Proteins known as transcription factors interact with these cis-regulatory elements to specify the level, timing, and spatial expression of genes. Changes in the sequence of cis-regulatory elements, or the activity of transcription factors that interact with them, can have functional consequences during development. In fact, such changes are hypothesized to be the primary basis for differences in the anatomy, physiology, and behavior of organisms (including disease susceptibility in humans).
My research utilizes the sea urchin as a model system to explore the functional consequence of changes in genes and their cis-regulatory elements with regard to protein-binding affinity, patterns of gene expression in the embryo, and/or phenotype. In particular, I am interested in genes associated with skeletogenesis given key differences between derived species and the "primitive" pencil urchin. My students and I have recently characterized the expression of several genes in the pencil urchin and gained critical insight into the evolution of the larval skeleton, in collaboration with biologists at Caltech (Erkenbrack et al., 2016). I am now focused specifically on genes associated with epithelial-mesenchymal transition (EMT). The skeletogenic cells make this transition before migrating to their final location; there has been a shift in the timing of their migration during sea urchin evolution. Thus, our efforts to characterize these genes and their transcriptional regulation in several species including the pencil urchin will provide insight into this heterochronic shift, as well as the process by which cancer cells become metastatic through EMT.
