    Background

    At a young age, my interest in science was kindled by science fiction stories, comic books, and Star Trek: The Next Generation. My fondness for chemistry developed in high school, where I was fortunate to have a skilled and devoted chemistry teacher. While working on my doctorate in West Lafayette, Indiana, I discovered a deep satisfaction in mentoring collegiate students. As the graduate of a small liberal arts college in the Milwaukee area, I hoped to find a faculty position at a similar institution, and was fortunate to be called to WLC. Outside of my academic duties and service activities, I enjoy reading, writing, and drawing. In addition to my vocation as chemistry professor, I am also blessed to be a husband and father. My wife and I enjoy playing board games, traveling, and spending time with our children.

    As a professor at WLC, my goal is to help students gain the chemical knowledge they will need to be successful, both in their chosen career path and as an educated citizen. I prefer using group learning activities to keep students actively involved and to promote critical thinking skills, since college is a time to hone the problem solving, interpersonal, and individual learning skills that students will need throughout their lives.

    Research Interests

    Water is abundant in biological and geological chemistry. Processes such as protein folding, self-aggregation, and micelle formation are just a few biochemical examples that are mediated – if not initiated – by water. Since many of these processes involve molecules with hydrophobic surfaces (those that “fear” getting wet and are repelled from – or by -water), understanding the behavior and structure of water molecules around such surfaces is critical to understanding the driving forces behind these processes. My dissertation work focused on using Raman spectroscopy to study water hydration structure around hydrophobic solutes.

    The chemistry department at WLC has several analytical instruments at its disposal, including mass spectrometry, optical spectroscopy (UV-VIS, IR, fluorescence), and atomic absorption spectroscopy. WLC students have assisted me in constructing a Raman spectrometer on campus, and our department recently acquired a nuclear magnetic resonance (NMR) spectrometer. One of my current research interests is to develop interdisciplinary collaborations with other departments and apply the aforementioned techniques (along with their associated chemical knowledge) to experimental research questions in these other disciplines. For example, my students and I have assisted the anthropology department in determining the copper content in archeological artifacts.

    Students often have their own research interests. I am always willing to talk to students about their interests and develop research projects that are exciting for both me and the student.
