Student and advisor

Participating in cutting edge research, whether at a computer screen or a lab bench, can be one of the most enriching experiences of your undergraduate career. Even if you think that you will not be going to graduate school or to an industry job that involves research, you should seriously consider working in a research group. The experience of working in a research group under the guidance of an experienced researcher will deepen your understanding of what you learned in the classroom. It will also sharpen your problem solving skills and ability to work independently. Additionally, you will make contacts with faculty members and graduate students who can help you with future career decisions.

Penn State chemistry majors have opportunities to work with some of the best research groups in the world on projects that have the potential to impact many of the most important issues facing our society today: energy; the environment; health and disease; the development of new materials. Each year nearly seventy-five percent of our majors work in a research group during the academic year or the summer term. Many of our student researchers receive a stipend when working during the summer term.

At least one semester of physical chemistry is recommended.

Gong Chen:  Our current research program covers four different areas of chemical and biological research: synthetic methodology/natural product synthesis, medicinal chemistry, chemical glycobiology, and cancer biology. Organic synthesis is the foundation of the whole program. We are interested in developing new synthetic methodologies based on transition metal catalyzed functionalization of C-H bonds. Those methodologies will be employed in the synthesis of complex natural products (especially novel non-ribosomal peptides) with interesting biological activities. Structure & activity students will be further carried out to explore their biological functions as either chemical probes or drug candidates. We are also interested in synthetic and biological studies of complex carbohydrates. Chemical synthesis of those carbohydrates and bio-conjugation with proteins, with the assistance of fluorescence imaging, will allow us to study their intrinsic function inside the cell. In addition to revealing their molecular mechanisms, we hope that these studies will facilitate the development of valuable carbohydrate-based therapeutic and diagnostic reagents. Moreover, we are interested in developing new epigenetic drug for cancer treatment.
