Georgia Tech's Space Research Institute Names Two Associate Directors

Posted September 22, 2026

The Georgia Tech Space Research Institute (SRI) has appointed David Ballantyne and Mariel Borowitz as associate directors, expanding the institute's leadership team as it continues to strengthen Georgia Tech's position as a leader in space research, education, and engagement.

Since its launch in 2025, SRI has brought together researchers from across campus to advance interdisciplinary space initiatives and create new opportunities for collaboration. In their new roles, Ballantyne and Borowitz will help guide the institute's growth by strengthening both internal research connections and external partnerships across the broader space community.

“David and Mariel bring complementary strengths that will be invaluable as we continue building SRI,” said Jud Ready, executive director of SRI. “David has a deep understanding of the research enterprise at Georgia Tech and a passion for connecting people and ideas across disciplines. Mariel brings extensive experience working across government, industry, and the international space community. Together, they will help us strengthen Georgia Tech's space ecosystem and expand our impact far beyond campus.”

Strengthening Georgia Tech's Research Community

Since joining the Institute in 2008 as a founding faculty member of the Center for Relativistic Astrophysics, Ballantyne has helped advance both space science and academic leadership across campus.

A professor in the School of Physics, he studies the evolution of galaxies and their central black holes, as well as the physics of accretion disks around black holes and neutron stars. He has authored more than 140 peer-reviewed publications and served as associate chair of the School of Physics for nearly a decade.

As associate director, Ballantyne will focus on cultivating connections across Georgia Tech's space research community and identifying opportunities for new interdisciplinary collaborations.

“I view SRI as a catalyst — a mechanism to spark new and transformative areas of space research at Georgia Tech that will grow to national and international prominence,” Ballantyne said. “There is so much innovative space research happening across campus, and one of SRI's most important roles is helping researchers find the connections and collaborations that can spark new ideas and discoveries.”

Ballantyne says he is particularly interested in helping position Georgia Tech as a leader in understanding the opportunities and challenges presented by artificial intelligence in space systems.

“My goal is to be out in the community, learning about the breadth of space research happening across campus and identifying ways SRI can accelerate that work,” he said. “AI technologies are poised to transform space exploration, scientific discovery, national security, and commercial space operations. SRI is uniquely positioned to help Georgia Tech lead those conversations.”

Building Partnerships Beyond Campus

As space activities become increasingly interconnected across government, industry, and academia, strong partnerships are essential to translating research into real-world impact. That collaborative spirit is central to the work of Mariel Borowitz, an associate professor in the Sam Nunn School of International Affairs.

Borowitz, who also serves as director of Georgia Tech’s Center for Space Policy and International Relations, is widely recognized for her expertise in space policy, international cooperation, and the governance of emerging space activities. Her work has connected her with space agencies, private companies, and policymakers around the world, providing a valuable perspective on opportunities for Georgia Tech to expand its engagement with the broader space community.

In her role as associate director, Borowitz will focus on growing SRI's partnerships with industry, government, and the broader space community.

“My focus as associate director will be on building partnerships between Georgia Tech and the broader space community,” Borowitz said. “Georgia Tech has tremendous expertise across science, engineering, policy, economics, and international affairs. By working across those disciplines, we can help address the complex challenges facing the future of space development while creating new opportunities for collaboration and impact.”

Borowitz sees SRI as a powerful mechanism for connecting Georgia Tech's diverse strengths and amplifying their collective impact.

“Real-world challenges and opportunities are inherently interdisciplinary,” she said. “The Space Research Institute allows us to bring together expertise from across Georgia Tech to develop more complete solutions and create new possibilities for the future of space.”

Looking Ahead

Together, Ballantyne and Borowitz will help advance SRI's mission of connecting researchers, educators, students, industry leaders, and policymakers to address the most pressing opportunities and challenges in space.

“Space exploration has always challenged us to think bigger, work across boundaries, and pursue questions that no single discipline can answer alone,” said Ready, who also serves as a principal research engineer at the Georgia Tech Research Institute. “David and Mariel embody that spirit of collaboration, and their leadership will help us create new opportunities for discovery, innovation, and impact at Georgia Tech and beyond.”
