Research Interests: My research team study enzymes, mainly the homodimeric glutathione synthetase, important in the biosynthesis of the body’s most important natural antioxidant, glutathione. Experimental and computational techniques are integrated to understand how this key enzyme works. Glutathione protects against many things (toxins and aging). Diseases such as HIV, Parkinson’s and Alzheimer’s are associated with glutathione deficiencies. My research team (undergraduate and graduate students) work on increasing knowledge of protein-protein interactions, designing better enzymes and therapies for glutathione deficiency.

Research Interests:Our research investigates the role played by the bulk enzyme structure in the enzyme catalytic event. Specifically we are testing a hypothesis, the Shifting Specificity Model, to explain enzyme catalysis generally. Our experiments involve kinetic and thermodynamic measurements of interactions of enzymes with catalytically relevant ligands.

I want to know more about how TWU science core courses can improve science teaching. SCI 2103 is a SENCER course (see http://www.sencer.net/) designed to generate better retention of science knowledge among non-science majors. Student surveys will be used along with course assessments to measure perceived changes in preparedness. This work is partially supported by a grant from the National Center for Science and Civic Engagement (see http://www.ncsce.net/). In the Fall 2008 term I began a Scholarship of Teaching and Learning study as it relates to students enrolled in Fundamentals of Science (SCI1003), a course designed to assist students performing below college level in math and science. The purpose of the study is improve student success in college.

Research Interest: Our research focuses on the conformational properties of nucleic acids: conformation, conformational transitions, ligand binding, and the thermodynamics associated with conformation, conformational transitions and binding. We are primarily interested in how sequence context and environmental conditions influence these properties. We use a variety of biophysical techniques such as UV/Vis and circular dichroism spectroscopies, differential scanning calorimetry and isothermal titration calorimetry.
We are particularly interested in the interaction specificities of a new class of synthetic porphyrazines with DNA. Preliminary results indicate that these compounds can bind to DNA through electrostatic and hydrophobic recognition. The primary focus of this work is to determine any specificity in the binding with regards to DNA sequence and secondary structure.
