Heungman Park is driven by his desire to transform fundamental physics discoveries into practical applications, which is why his research focuses on applied physics. His research team is investigating organic semiconductors in pursuit of a future where inexpensive plastic materials are used in highly efficient solar cells and light-emitting devices.

Park arrived in Oregon to begin his journey as a physicist in 2002, earning his master's degree from Oregon State University and a doctorate from Vanderbilt University. During his academic years, he enjoyed research and teaching.

A Conversation with Dr. Park

Which research projects are you working on now?

My research projects are on organic semiconductors in applied physics. Particularly, I focus on fundamental understanding of charge carriers and their binding states for the application of optoelectronic devices such as light-emitting diodes and solar cells. Organic semiconductors have a bright future for lightweight, flexible and low-cost device applications. In the future, people may carry thin, plastic portable solar cells in their backpack to charge their smartphones.

How has A&M-Commerce helped with your research?

The Department of Physics and Astronomy strongly encourages students to participate in faculty research programs. Students’ involvement is critical to helping me pursue my research projects at A&M-Commerce.

What hobbies do you have outside of teaching and researching physics?

I enjoy computer programming with Python for smartphones.
