Instrumentation Experience
The two instruments I have worked with most often are the HPLC and the UV-Vis. I feel quite comfortable using these machines, as well as troubleshooting the machines and software when problems arise. The following links contain information about my experience with these machines, procedures, and examples of data I have collected.
Interests
I was fortunate enough to join the Monmouth College Chemistry Department on a short study abroad trip to the Bahamas where I was able to gain first hand experience in the ocean environment.
The following link goes into more detail about the trip.
Career Goals
My goal is to attend a graduate school to pursue a PhD program in an environmental chemistry field. My research interests are focused around the fields of organic or analytical chemistry, but I am also comfortable with physical or inorganic chemistry. I am also interested in oxidation chemistry, but any type of chemistry in the environmental field is within my range of interest. Instrumentation I prefer to work with includes the HPLC and the UV-Vis, but I am also familiar with many other types of instrumentation.
Data Analysis Software Links
I have created these links for current and future Monmouth College students to visit when they are learning about these types of software.
