Bradley E Sturgeon

Monmouth College faculty Profile

BIO

Brad received a BS/MS in Chemistry from Illinois State University in 1987/1989 and a PhD in Physical Chemistry from the University of California, Davis in 1994. Brad was a postdoctoral fellow at Northwestern University, University of Chicago Medical Center, and the National Institute of Environmental Health Sciences/NIH. Brad's professional life has been spent in academia ranging from teaching at a residential science and math high school through major research university. Brad settled in to the liberal arts college environment in 2007 by joining the faculty at Monmouth College. Brad currently teaches sections of General Chemistry and Physical Chemistry (Thermodynamics/Quantum Mechanics) and promotes a strong hands-on lab experience. Brad's research program includes the detection of enzyme-generated radical intermediates using ESR/EPR spectroscopy, detection/identification of radical-derived products using HPLC, and application of computational approaches to understanding electrostatic mapping of unpaired electrons in small organic radicals. Brad has studied the science underlying coffee, beer, and fireworks and has acquired a collection of "maker" tools including 3D printers (FDM/SLA), laser cutter/etcher, and wood-metal-glass working equipment. Brad is married to his wife Katherine (since 1994) and has raised 2 adult children, both having attended fine liberal arts colleges (Monmouth and Luther).

TEACHING/RESEARCH EXPERIENCE

Associate Professor, Physical Chemistry, Monmouth College, 8/14-present Same as below.

Assistant Professor, Physical Chemistry, Monmouth College, 8/07-8/14. I teach and conduct independent research in the area of physical and biophysical chemistry. Course work includes: Thermodynamics and Kinetics (Physical Chem I), Quantum Mechanics (Physical Chem II), Physical Chemistry Laboratory, Computational Chemistry, Environmental Chemistry (non-majors), General Chemistry, and General Chemistry laboratory. Additionally, I teach, within the College’s Integrated Studies curriculum, a course on Citizenship related to green initiative and “water” and Global Initiatives related to food. My research program involves the direct detection of free radicals from enzymatic reactions. This program has both an experimental and computational approach. Techniques utilized include: Electron Spin Resonance (ESR), HPLC, electrochemical sensors (dioxygen, hydrogen peroxide, and nitric oxide), UV-Vis, and general lab techniques (buffers, solution prep, pH, compressed gases, etc). Computational efforts use a combination of DFT/B3YLP methods run through WebMO/Gaussian®.

Adjunct Faculty, Chemistry, Hood Collage and McDaniel College, 8/06-5/07. At Hood College I taught their “Discover Chemistry” general chemistry course. This laboratory-based, inquiry-based course is a where students spend three, 2-hour lab sessions per week exploring general chemistry principles traditionally taught in a lecture-style. At McDaniel College I taught Qualitative Analysis. This course has been previously taught in a very traditional fashion including a “glassware-based” laboratory. I was asked to modernize this course to include available instrumentation. The lab portion of the course was “presented” as a fictitious Contract Research Organization working in the “spirit of GLP.”

Assistant Professor, Physical Chemistry, Western Carolina University, 8/03-12/05. Taught and conducted independent research on enzyme biochemistry. Course work included: Thermodynamics and Kinetics (Physical Chem I), Quantum Mechanics (Physical Chem II), Chemical Dynamics Laboratory (Physical Chem Lab), Computational Chem (elective), general chem, and general chem laboratory. My research program involved the evaluation of enzyme and free radical chemistry. This biochemical research utilized: HPLC, electrochemical sensors for dioxygen, hydrogen peroxide, and nitric oxide, electron spin resonance, UV-Vis, and general lab techniques (buffers, solution prep, pH, compressed gases, etc). During the summers of ‘04 and ’05 I was the lead instructor for the NC Summer Ventures in Chemistry program. This 4 week, ~6 hrs per day program was directed at academically gifted high school students. My programs focused on enzyme biochemistry. The current dept. head is Prof. Cynthia Atterholt (atterholt@email.wcu.edu).

Visiting Lecturer, Analytical Chemistry, Univ. of North Carolina-Chapel Hill, 8/02-5/03. Taught Analytical Chemistry to science majors. The goal of this course was to introduce the fundamental concepts underlying analytical chemistry. There was a continuous emphasis on the “the analytical process”. This course covered the following topics: 1) acid/base chemistry, 2) analytical separations (general chromatography, GC, HPLC, capillary electrophoresis), 3) spectroscopy (UV-Vis spectroscopy), and 4) electrochemistry. Topics such as experimental error, statistics, and calibration were discussed in the context of the topics above. Course management was required due to the 200+ students enrolled. The current dept. head was Prof. James Jorgenson (jj@unc.edu).

Instructor, Chemistry, North Carolina School of Science and Math (NCSSM), 8/00-6/02. Taught chemistry to academically gifted junior and senior high school students accepted to this 10-month residential high school. The position responsibilities included: preparation of course and laboratory content, management of student records, and administrative responsibilities involving committee assignments, departmental meetings, grant preparation, and student discipline issues. The current dept. head is Myra Halpin, Ph.D. (halpin@ncssm.edu).

Chemist (GS-12/13, 1320), summers ‘01, ‘02, ‘03. National Institute of Environmental Health Sciences (NIEHS), Laboratory of Pharmacology and Chemistry, Research Triangle Park, NC. Advisors: Ronald P. Mason, Ph.D. (mason4@niehs.nih.gov) and Tom Burka, Ph.D. (bruka@niehs.nih.gov) This was summer employment during the years I taught. Projects related to IRTA at NIEHS/NIH immediately below.

Intramural Research Training Award (IRTA), 7/97 – 8/00. NIEHS, Laboratory of Pharmacology and Chemistry, Research Triangle Park, NC. Advisor: Ronald P. Mason, Ph.D. (mason4@niehs.nih.gov) Researched the role of free radical species involved in oxidative stress. Investigated the role of peroxidase enzymes in the formation of endogenous and exogenous substrate radicals. Directly detected free radicals using rapid-flow electron spin resonance (ESR) and indirectly using ESR spin trapping. Developed immobilized enzyme ESR method for enzymes that are not available in quantities necessary to perform rapid-flow measurements.

Post Doctoral Research Fellow, 1/96 - 6/97. University of Chicago Medical Center, Department of Radiation and Cellular Oncology. Advisor: Howard J. Halpern, Ph.D., M.D. (howard@rover.uchicago.edu) Projects involved biomedical research using a locally constructed 250 MHz Electron Spin Resonance (ESR) spectrometer. Investigated, in cellular systems, the role of anti-oxidant enzymes in the protection of cellular components from reactive oxygen species. Also used spin probes to determine in vivo oxygen concentration (oximetry) and viscosity, assisted in implementing multi-dimensional ESR imaging of tumors, and applied ESR spin trapping to reactive oxygen species.

Post Doctoral Research Fellow, 1/94 - 12/95. Northwestern University, Department of Chemistry, Evanston, IL. Advisor: Professor Brian M. Hoffman (bmh@northwestern.edu). Performed electron magnetic resonance studies on biological metalloenzymes, specifically carboxylate-bridged diiron centers. Used 35 GHz continuous wave (CW) Electron Paramagnetic Resonance (EPR)/Electron Nuclear Double Resonance (ENDOR) and 35 and 9 GHz pulsed EPR/ENDOR.

Graduate Research Assistant, 9/89 - 12/93. University of California, Davis, Department of Chemistry, Davis, CA. Advisor: Professor R. David Britt (rdbritt@ucdavis.edu).
