Field of Interest:
My research interests are interdisciplinary in nature,
spanning the traditional boundaries of synthetic organic chemistry,
biochemistry and molecular biology. I am
interested in the chemistry of biological surfaces, particularly those that
contain sugars, and the role of the sugars at these surfaces.One project in my group looks to develop a
model system for glycosylated surfaces. While cell surfaces are covered in carbohydrates, many of the details
concerning interactions with carbohydrates are yet to be uncovered. In particular, we seek to develop a model
system that contains sugars fixed in space and orientation to an extended sheet
surface that will allow for the probing of sugar-sugar and sugar-conjugate interactions
at defined spacings. My larger interest
in surfaces containing sugars led me to an interest in bacterial cell
walls. These cell walls contain a system
of cross-linked sugars and peptides called peptidoglycan whose synthesis is the
target of many commonly used antibiotics. A second on-going project studies the proteins that synthesize this
peptidoglycan, called penicillin-binding proteins (PBPs), from the bacterial
species Burkholderia cenocepacia. This bacterium is an opportunistic pathogen
that is of clinical relevance to Cystic Fibrosis patients. It is of particular interest because it is
largely resistant to antibiotics, and utilizes many resistance mechanisms. In my lab, we have identified, cloned, expressed,
and isolated several PBPs from this bacterium. We have begun studies to characterize these proteins.
I have a
strong interest in working with undergraduate students and many students who
have worked in my lab have presented their work at national conferences.
I am also interested in the research
regarding the best pedagogies for teaching chemistry. This has translated into lab development and
classroom strategies that explore techniques current in the literature.
