My research focuses on discovering combinations of metal oxides for harvesting sunlight to split water thereby generating hydrogen gas a green fuel which does not contribute to global warming. Students utilize an array of LEDs connected to an electrochemical cell to examine the ability of metal oxides to absorb visible light to serve as possible semiconductors for producing hydrogen. Other areas of my research include investigating small molecule interactions with transition metal complexes.
Applications to engineering, medicine, biology, and everyday life are introduced in my General Chemistry course. Students have enjoyed working in pairs presenting chemical demonstrations to one another and explaining the concepts involved in my ChemTech class. Students enhance their learning about the active sites of enzymes and medical applications of drugs through their own presentations and the incorporation of interactive molecular models in Advanced Topics in Inorganic Chemistry.
It is a pleasure to interact with students in discussions about college courses and activities, careers and job opportunities. I enjoy inviting Thiel alumni to give talks to current students sharing their successes as well as challenges in careers in education, chemical industry, and the health-related professions. In these presentations, alumni also relate their experiences in graduate and professional schools. These interactions assist students in obtaining internships, work opportunities, and ideas for future employment and post-graduate education.
