- Analytical Chemistry
- Quantitative and Instrumental Analysis
Analytical chemistry is based on the notion that we cannot understand what we cannot measure. No matter what area of science an individual goes into, they will have to make reliable measurements and interpret data in order to fully understand their results. My teaching philosophy is based upon this tenet and I use it to motivate students to go beyond simple memorization and apply their newly found knowledge to every aspect of their science education. My teaching interests involve General Chemistry II (CHEM 112), Quantitative Analysis (CHEM 221), Instrumental Analysis (CHEM 440), as well as the instrumentation laboratory experiments for upper level students (CHEM 441 and 443). Quantitative Analysis deals with learning how to make analytical measurements, and how our understanding of chemical behavior in a given sample affects these measurements. In the Instrumental courses, I attempt to remedy a student’s “fragile black box” perception of scientific instruments and let them see what is inside an instrument and how different settings impact the analytical measurements. The experiments are designed to encourage a student to be independent and confident in the laboratory.
My research expertise is in the broad area of electrochemistry, specifically electrocatalysts, sensors, and materials. The main focus of my research is the development of electrochemical sensors to study dissolved gases in biological and environmental media. For example, hydrogen sulfide (H2S), nitric oxide (NO), and carbon monoxide (CO) are three gases produced endogenously within the body known as gasotransmitters. These molecules serve several physiological functions and may be involved in several neurological diseases. Electrochemistry is ideal for monitoring these gases in real-time due to its potential for sensitivity, selectivity, and miniaturization. However, due to current material limitations, there is no way of selectively monitoring one gas in the presence of the other two. This is extremely problematic in ascertaining the specific roles of each molecule and understanding how they interact with each other. We are currently investigating potential electrocatalytic materials that will selectively oxidize H2S over both NO and CO.

Electrochemistry is a branch of chemistry that studies chemical processes that involve the transfer of electrons. My main interest is to use this principle to develop a sensor capable of detecting hydrogen sulfide, a gaseous molecule produced in the body in very small quantities that is directly related to cardiovascular and central nervous system health. Additional projects in my group involve using electrochemical methods in order to better understand various reactions that involve electron transfer.
