Teaching Interests

General Biochemistry I. CHEM5071
This is a three credit course, with three lecture hours per week. Chemical characterization of proteins, lipids, carbohydrates, and nucleic acids; principles of enzymology and bioenergetics, recombinant DNA techniques, introduction to carbohydrate metabolism and biological oxidations.

General Biochemistry Laboratory II. CHEM5074
One credit hour. Four hours laboratory per week. Co-requisite: CHEM5071 The use of bioinformatics, structural genomics, and the molecular modeling in the spectroscopic characterization and analysis of biological molecules.

Undergraduate Research I. CHEM4998
One to three credit hours. Three to nine hours of research per week. Pre-requisite: Authorization of the Director of the Department. Introduction to chemical research under the supervision of professors of the Chemistry department.

Undergraduate Research II. CHEM4999
One to three credit hours. Three to nine hours of research per week. Pre-requisite: three credits in CHEM4998. A research project under the supervision of professors of the Chemistry department. Advanced undergraduate and graduate.

Advanced Biochemistry. CHEM6715
Three credits, three hours of lectures per week. Study of the structure and function of biological macromolecules, such as nucleic acids and proteins. Discussion of biological membranes as fundamental components in cellular function. Analysis of macromolecules by advanced instrumental techniques.

Biophysical Chemistry. CHEM6016
Three credit conference hours. Pre-requisite:CHEM6715 Spectroscopic methods, molecular simulation, bioenergetics, reaction kinetics, and solution thermodynamics applied to nucleic acids, proteins, and other biological molecules.

Bioinformatics, Proteins, and Protein-Protein Interactions. CHEM8995
Four credits, four hours of lectures per week. Pre-requisite: CHEM6715 Bioinformatics its basic concepts, methods, and tools to assess protein sequence structure and function; and the use of molecular biophysics to study proteins and protein-protein interactions. Specifically, the students will have a hands-on approach to using bioinformatics databases to analyze sequences, phylogeny, protein homology, identifying common protein motifs and domains, and protein-protein interactions. Advanced analysis of thermodynamic and spectroscopic data will be performed to understand protein unfolding, relative stability, and protein-protein interactions. Molecular modeling will also be used to discuss protein structure and protein complexes.

Graduate Co-op Project. CHEM6994
Credits: 3 credit hours, may be repeated once. New Special Topics course allowing graduate students have a work experience in the industry. The student must be in good standing, have a letter offer describing his/her responsibilities, tasks, period of work, immediate supervisor, division, company address and contact information. A Co-op collaboration agreement. Supervisor and advisor evaluations, mid-term report and final oral presentation are required. Guidelines for mid-term report and oral presentation, course syllabus, evaluation forms and collaboration agreement are included.

Chemistry Research I, II, S. CHEM6998
Six credit hours. The student will choose a member of the faculty as his adviser. Presentation of a thesis is required for credit.

Research Interests

Understanding protein interactions and their function by the use of molecular biophysical techniques.
