G. Marc Loudon

My laboratory research interests are in mechanism-based drug design, organic reaction mechanisms in aqueous solution, enzyme mechanisms, and peptide chemistry. My last projects included the design, synthesis and evaluation of a family of aziridine-based inhibitors of the HIV protease, carboxy-terminal peptide degradation, and site-specific peptide cleavage reactions. Because of my activities in administration and teaching, I do not have a regular research group. However, I am available to serve on committees and to co-direct projects in other laboratories that are within my areas of expertise.

I am also studying (in collaboration with George Bodner in the Department of Chemistry) teaching and learning in organic chemistry. A current project involves comparison teaching of sophomore organic chemistry using cooperative learning and standard lecture approaches.

My current active interests are in university administration, teaching, and the developing of instructional materials. I am the author of Organic Chemistry, 5^th Edition, published by Roberts and Company, and am a co-author of both Study Guide and Instructor Supplement to accompany that text. I have, in collaboration with George Bodner in the Division of Chemical Education, been developing a group-study approach to teaching organic chemistry, which has been implemented in the last several years in my organic chemistry course at Purdue (which has between 200-300 students). I am currently interested in working on a revision of the chemistry curriculum for pre-pharmacy, pre-medical, pre-biology, and pre-veterinary students.

Associate Dean for Research and Graduate Programs for the College of Pharmacy, Nursing, and Health Sciences, 1988-2007.

My principal teaching responsibilities are MCMP 204-205 (Organic Chemistry)
