Biography:

Mark Spaller is currently Associate Professor of Medical Education at the Geisel School of Medicine, and Associate Professor (Adjunct) of Chemistry and Biological Sciences at Dartmouth College. He completed his doctoral studies at the University of Texas at Austin, where he conducted research in the fields of synthetic organic chemistry and protein biochemistry. This was followed by a move to the University of California, Berkeley, where he served as an American Cancer Society postdoctoral fellow, devising new synthetic methods for use in preparing chemical libraries for drug discovery screens. He began his independent academic career at Wayne State University, as a member of the biochemistry division in the Department of Chemistry, where he first immersed himself as a teacher of full-term classes in both the undergraduate and graduate programs. During this period, he also established an NIH-funded research laboratory that focused on the development of peptides and proteins for use as biochemical and biological tools in basic and translational applications. He subsequently moved to Brown University, and then again in 2008 to Dartmouth. Prof. Spaller is course director for Pharmacology for second-year medical students in Geisel, and also teaches both in the graduate and undergraduate curriculum, the latter within the College’s departments of Biological Sciences and Chemistry, as a member of the Arts & Sciences faculty. In addition, Prof. Spaller directs an independent research laboratory within the Norris Cotton Cancer Center, which explores the use of small molecules, peptides and proteins in biomedical applications, and which has developed a number of collaborative partnerships with other research laboratories within and outside Dartmouth College.
