An exciting feature of the B.S. degree program in chemistry is involvement in a full year of original research. Students normally fulfill this requirement during their senior year, after they have completed courses in organic, inorganic, physical, and analytical chemistry and basic courses in physics and mathematics. Research opportunities are also available for B.A. majors andMcDonnell-Barksdale Honors College students, and multi-year projects are possible. Continuing research activities in the department offer opportunities for investigation in a large variety of projects, encompassing every area of chemistry and biochemistry and extending into interdisciplinary areas.

Research Course Policies
1. CHEM251 and CHEM 351 can be taken by any student (B.A. or B.S.) who wishes to receive graded credit for doing research with a faculty member in the Department. A student will receive a grade for this course at the end of each semester of enrollment. This grade will reflect the student’s level of participation, effort, and progress. No “I?grade will be issued for this course. Individual professors maintain the class roll for those students who are doing research in their laboratories.May be repeated for credit up to maximum of 9 hours.

2. CHEM 463 is also open to students who wish to receive graded credit for doing research with a faculty member, but a student taking this course must prepare a written paper (or Honors College thesis) and present an oral or poster presentation. The department chair will maintain the class roll for all students enrolled in CHEM 463. The faculty member supervising the student’s research recommends a grade, but the grade will not be posted until the final written report has been received and approved.

3. CHEM 463 is a required course for both the B.S. chemistry and forensic chemistry degrees. However, the way in which this course is used in these two programs is different:

4. The B.A. chemistry and biochemistry degree programs do not have a research requirement. However, students seeking these degrees who do become engaged in research would normally take CHEM 351, but are not precluded from taking CHEM 463. However, B.A. students enrolled in CHEM 463 are subject to the requirements listed above in #2. In selected cases, CHEM 463 may be substituted for CHEM 472.

5. Both CHEM 351 and CHEM 463 may be taken up to a maximum of 6 hours.

RESEARCH SUMMARY
Imaging electrochemical reactions and biological phenomena at the nanoscale and single entity level can provide rich details on 1) heterogeneity in the system and 2) enhanced mechanistic insights that are not possible with traditional electro- and bio-analytical tools. The Sundaresan Lab vision is to use and develop high-throughput multimodal imaging techniques such as optical, electrochemical, and electron imaging to understand electrochemical and biological phenomena at the single entity level and utilize the obtained insights to design better performing catalytic and biological systems at the ensemble level. Accordingly, the group will focus on interfacing novel high-resolution optical imaging techniques, including super-resolution imaging, with electrochemical techniques that can address fundamental scientific questions in the fields of electrocatalysis, materials science, and biology. Additionally, the developed methodology can be used to design ultra-sensitive chemical and biosensors.
