Sam Hart 
Third-year SSDL Ph.D. Student
Research: “My research focuses on propellant management with applications to small satellites and CubeSats. This spans analytical, numerical, and experimental work. Thanks to the extensive resources within the LGST and the Space Systems Design Lab (SSDL) we are able to rapidly prototype and test hardware to demonstrate novel PMD technologies. It’s my hope that this work will enable a more capable next generation of CubeSats.“

Eric Anthony Comstock
First-year Ph.D. Student
Research: “I am a Ph.D. student at Georgia Tech working for Dr. Romero-Calvo in the LGST lab. I started my journey at Texas A&M University, which has prepared me well for this position. My research interests include computational fluid dynamics and modeling of electromagnetic systems and of hypersonic flows. I chose the LGST lab due to my extreme enthusiasm for technologies with the potential to help humanity colonize the solar system, and beyond. The LGST lab is a great opportunity due to the high applicability of its projects to near-future space technologies. Additionally, I look very forward to collaborating with any new team members joining this incredible adventure!“

Theo St. Francis
Incoming Ph.D. Student (January 2024)
Research: “I’m looking forward to joining Prof. Romero-Calvo’s lab in January 2024 to help develop the 21st-century fluids infrastructure required for long-duration human spaceflight. My prior experience includes summers spent on Structures and Propulsion at Relativity Space, as well as designing, building, and firing a methane-oxygen engine to 400psi with a classmate. As we prepare for the eras of Starship – including microgravity cryogenic propellant transfers and a massive reduction in specific cost to orbit – as well as Artemis – with long-duration human spaceflight and a re-established presence in the lunar environment – we will require both new science and technology to manage fluids for these missions. At LGST my research will focus on propellant management, electrolysis for life-support, and lunar dust mitigation.“
