Mark Stocksdale
Professor of Chemistry

Mark Stocksdale is a professor of chemistry who teaches courses in organic chemistry. He collaborates with his students on research projects. Most recently they have been synthesizing analogs of phytosiderophores, the natural cellular iron-transport system used by grass species.

Mark says of teaching at Earlham, "I really enjoy watching students learn and discover chemistry. I work hard to find multiple methods to positively encourage students in their studies of chemistry, and I often see myself as their 'coach,' someone that can recognize their talent, show them how to expand and develop their abilities, and then encourage and enable them to attain their goals and move them even farther than they could have imagined."

Selected Courses:

I regularly teach the following courses: Organic Chemistry I and II, Advanced Organic Chemistry, and Medicinal Chemistry.

Though largely responsible for the Green Revolution, the application of agrochemicals has a detrimental impact on the environment. One way to diminish this impact is to reduce the application rates of these chemicals through targeted delivery. Grasses, which represent the economically most important group of plants, secrete molecules called phytosiderophores that bind and transport iron to the plant through the roots.  My research group and collaborators are studying this iron acquisition strategy to selectively target grasses for molecular delivery. Students working with me on this project collaboratively design and synthesize natural and unnatural phytosideropores as well as intermediate molecules required for our ongoing evaluation of growth studies. Each student working on this project regularly utilizes state-of-the-art instrumentation such as nuclear magnetic resonance (NMR), infrared spectroscopy (IR), and automated flash chromatography to isolate, purify, and characterize each of their synthesized products. Results from each student's work contribute to the overall goals of the project, and they get to present their work at regional and national scientific meetings.

My research interests involve the design and synthesis of new biologically and/or structurally interesting organic molecules.  Most recently, students working with me have been synthesizing analogs of phytosiderophores, the natural cellular iron-transport system used by grass species.  We also collaborate with a molecular biologist for testing and evaluation of our final compounds in growth studies.

I really enjoy watching students learn and discover chemistry. I work hard to find multiple methods to positively encourage students in their studies of chemistry, and I often see myself as their “coach”, someone that can recognize their talent, show them how to expand and develop their abilities, and then encourage and enable them to attain their goals and move them even farther than they could have imagined. At Earlham, this is a daily experience for me in which I am afforded the opportunity to work with students and observe their intellectual growth both in regular classroom settings and as collaborators in research projects.

Being a professor at Earlham keeps me quite busy, but when I do find time to explore other activities, I enjoy attending music concerts with my youngest son and going to car shows and working on cars with my oldest son. As an organic chemist, I really enjoy making things. As such, I like to cook, bake, grill, etc. whenever possible. I also love to go places with my family; I find traveling to new and old locations both near and far is fun and fulfilling.
