Biography

Christian Hamann earned his B.S. in Chemistry at Lebanon Valley College after completing an A.A. at Ocean County College that included a semester at the Collegium Palatinum in Heidelberg, Germany. He followed his Ph.D. from the Department of Chemistry at the University of Pennsylvania with a postdoctoral fellowship at the Thomas Jefferson University and then a stint in the Cancer Research Department at the Merck Research Laboratories. After a visiting assistant professorship at Franklin & Marshall College, Dr. Hamann joined the faculty at Albright College in 2001.

Areas of Research

Modeling the Biosynthesis of Terpenes and Their Atropisomers

The Hamann lab applies a variety of techniques to propose and investigate models for the biosynthesis of terpenes, a class of secondary metabolites that are found in all known organisms. Current molecules of interest include humulene (one of the flavoring agents in Humulus lupulus, beer hops) and seychellene (a fragrant oil from Pogostemon cablin, patchouli). Work in this area has led to computational studies on atropisomeric systems, chiral molecules with no chiral centers that interconvert via a series of conformational changes. Further, his laboratory has developed a successful approach to organizing computational data from terpene conformation experiments that supports research productivity with a searchable database.

 

Pedagogy, Undergraduate Research, and Outreach

Prof. Hamann also develops classroom teaching methods and laboratory experiments that provide students with meaningful learning experiences that support both in-course success and long-term, positive educational outcomes. Other areas of interest include supporting undergraduate research (he is an elected member of the Council on Undergraduate Research) and promoting opportunities for chemists with disabilities (he is a member of the Committee on Chemists with Disabilities of the American Chemical Society). He regularly publishes with his students and fosters opportunities for his students to present their work at local, regional, and national conferences. Students who present their work meet both fellow undergraduate research students and notable scientists. In addition to increasing the enjoyment of the conference, these connections often lead to graduate and professional placements.
