Welcome to the Department of Chemistry

From nanoparticles to macromolecules, chemistry is the study of matter, its properties and applications. Advances in chemistry have resulted in major improvements to society in the forms of better medicines, new types of energy and superior materials.

At USD, our chemistry faculty are award-winning teachers and internationally recognized researchers who are leaders in their field. Our in-depth curriculum gives students the tools you need to succeed in future careers, postgraduate studies or anything you do next. In the department, you will also have many opportunities to do research with world renowned faculty in the areas of energy, security, catalysis and computational chemistry. Our graduates go onto careers in medicine, dentistry, the chemical industry, secondary school teaching, and become researchers. Chemistry students are among the highest achieving at USD and earn numerous nationally competitive scholarships, including USD's 10th Rhodes Scholar.

Join our community of researchers, innovators and educators in the USD Department of Chemistry.

If you are looking for a exemplary group of scholars who support and foster exploration and research, the USD Department of Chemistry is the place for you.

Summer Research Program

The Molecules Meet Materials (M3) Research Experiences for Undergraduates (REU) site at the University of South Dakota, located in Vermillion, SD, supports the training of 10 students for 10 weeks during the summers of 2022-2024. In this program, funded by the National Science Foundation Division of Chemistry, participants pursue collaborative research projects. All students also take part in a professional development and ethics training program, with a focus on science communication and preparation for graduate school or industrial careers.

student success story

Taylor Ravelo smiling.
The knowledge that science brings has always struck my interest. Chemistry has been the right fit for me because I have an interest in the chemical components of making medications. I've developed skills that have paved my path towards pharmaceutical school. Due to my interpersonal relationships with my professors and faculty, I have obtained a wide range of knowledge to use in my professional career. Without them, I wouldn’t have been able to successfully be a student-athlete at USD.
