place where chemistry and biology meet. We are interested in
protein structure, activity and engineering. Because our projects
highly interdisciplinary, we collaborate with a number of other
research groups. Some of our current work is summarized below.
Enzymes as practical catalysts for organic
use enzymes to reduce alkenes stereoselectively. The goal is to
develop reactions that can be applied to the synthesis of valuable
organic compounds in both academia and industry. This work is
supported by the National Science Foundation and involves protein
engineering, X-ray crystallography and organic synthesis. Learn more...
Understanding and improving starch biosynthesis in corn. Corn's
economic value is largely determined by its starch
content. We are collaborating with research groups at U.F., Iowa
State University and the University of Wisconsin to identify and
eliminate bottlenecks in starch biosynthesis, particularly at elevated
temperatures. Our current work is supported by the U.S.
Department of Agriculture. Learn

Stewart group news
May 5, 2012
- Congratulations and best wishes to LTC Adam Z. Walton, who was
awarded a Ph.D. degree at the Spring 2012 graduation ceremony. He
will re-join the Department of Chemistry & Life Sciences at the U.S. Military Academy as a faculty member.
May 1, 2012 - A warm welcome to Athena Patterson-Orazem, who joined the Stewart group as an undergraduate researcher.
April 15, 2012 - A warm welcome to Sabine Leveque of the Universite Pierre et Marie Curie, who joined the Stewart group as a 2012 iREU participant.
February 10, 2012 - Congratulations
to Dr. Brad Sullivan (current post-doctoral fellow, Ph.D. 2009, Brock
University) and to Yuri Pompeu (current graduate student), both of whom attended RapiData 2012 at Brookhaven National Laboratory! This is a highly competitive program that taught cutting-edge techniques in protein crystallography at the National Synchtron Light Source on April 22 - 27, 2012.
February 9, 2012 - A warm welcome to Zakarie Wright, who joined the Stewart group as an undergraduate researcher.
The "Other" Jon Stewart
were looking for the host of The Daily Show
and landed here by mistake, this is the "other" Jon
Apart from his being younger, better looking and much wealthier, even
our mothers have a hard time telling the two of us apart.
