Space Research Institute for Discovery and Exploration

University of Cincinnati Space Research Institute for Discovery and Exploration aims to use the knowledge and competencies of our faculty, students, and partners to continue Ohio's extensive legacy of contributions to aviation and spaceflight.

Ohio is well known for its contributions in aviation and spaceflight. From the Dayton bicyclists, Wright Brothers, to spacefaring pioneers, John Glenn and Neil Armstrong, Ohio has been at the forefront of aviation, aerospace, and space exploration. While these accolades and laurels have been earned through innovation, discovery, and raw talent, it is the academic prowess that has been at the forefront. As we move into new areas of exploration, including robotic and human-tended missions beyond Earth’s orbit and the rapidly growing commercial space industry, we will harness the knowledge and competencies of our faculty, students, and partners. We will build on the foundation laid before us to achieve effective and lasting contributions in this new paradigm.


In 2007, UC was the recipient of a substantial monetary gift with the intent to create a space exploration research effort as well as the establishment of two endowed chairs, the Thomas Jefferson Endowed Chair for Discovery and the Alan B. Shepard Endowed Chair for Exploration. Each of these chairs will further develop the intent of exploration and discovery through their own innovative research. In addition, this gift continues to inspire the next generation of scientist and engineers across multiple disciplines.

UC was also the academic setting for Neil Armstrong after he left NASA. As professor of aerospace engineering, he inspired the next generation of aerospace engineers.

Meet the Director

The University of Cincinnati recently named Professor Charles Doarn as the inaugural director of the institute. Professor Doarn holds degrees from The Ohio State University and the University of Dayton. He serves as a Research Professor in the Department of Environmental and Public Health Sciences within the College of Medicine as is the Program Director of UC’s Master of Public Health. His full CV can viewed here.


Director’s Message –

I am delighted to support the UC Office of Research in this new endeavor. Most of my career has been at the intersection of medicine, public health, engineering and program management. While I remain fully engaged in medicine and public health with ties to NASA, it is my program management skills that I will apply to this new institute in helping shape the University of Cincinnati’s efforts in aerospace through mutually-beneficial partnerships with NASA’s aerospace engineering activities, the United States Air Force at Wright Patterson, industry partners, academia, and the State of Ohio in expanding our boundaries in education and discovery. Each new graduate of our engineering and applied sciences program as well as other disciplines within our vibrant urban campus will be better prepared as a result of their involvement with our faculty, collaborators, and this institute. Feel free to contact me by phone at (513) 558- 6148 or by email at

Faculty Chairs

Tomasz Stepinksi Portrait 

Tomasz Stepinski PhD

Thomas Jefferson Chair of Space Discovery

Beginning in 2010, Tomasz F. Stepinski, PhD established the Space Informatics Lab (SIL) in the McMicken College of Arts and Sciences’ Department of Geography. SIL’s mission is to develop intelligent algorithms and online tools for fast and intuitive exploration of large spatial datasets that originated from remotely sensed planetary data, including Earth data. Such tools give the scientific community and the public the ability to get insights from the entirety of the data, not just from individual images. Examples include automated mapping of craters and valley networks (dry river networks) on Mars, automated generation of mineral maps from hyperspectral images of Mars, and a tool that performs Earth-wide search for sites with landscapes and climates similar to a user-provided query. Stepinski has a PhD in Applied Mathematics and MS in Astrophysics. Before arriving at UC he worked at the Lunar and Planetary Institute in Houston, Texas. At UC he currently teaches a freshman-level course - “Exploring the Solar System” to introduce undergraduates to the topic of space exploration.
