Dunbar is a retired NASA astronaut, engineer and educator, currently with Texas A&M Engineering as a Texas A&M Engineering Experiment Station (TEES) Distinguished Research Professor in the Department of Aerospace Engineering. She also has a joint appointment as the Director of the TEES Institute for Engineering Education and Innovation (IEEI), and serves as director of the Aerospace Human Systems Laboratory.
Paul Burke is a Ph.D. candidate in Aerospace Engineering at Texas A&M University. He is from Bel Air, Maryland and is interested in partial gravity human space flight and multi-phase fluid systems. Paul is researching bubble formation and detachment in 1 g, partial gravity, and microgravity. Paul’s research will produce computational fluid dynamic (CFD) models of bubble formation and detachment from a submerged orifice across various gravity levels. By using an Earth-based experimental apparatus, 1 g bubble formation and detachment models will be developed and validated. The experiment includes a low speed gas injection system and a custom-built, multi-axis high speed imaging system. The 1 g models will then be extended and scaled to partial gravity levels. All CFD models are being developed using a Volume of Fluid (VOF) solver in OpenFOAM. Understanding bubble formation, growth, and detachment, specifically in microgravity and partial gravity, is a critical component of designing more efficient multi-phase thermal management systems, phase separators, and life support systems.
Dillon Hall is a Ph.D. student in Aerospace Engineering at Texas A&M University. He is from Saltillo, Mississippi, and is interested in space suit design. Dillon’s primary research focuses on analyzing previous space suit designs from Apollo-era to present day in order to determine engineering variables that contribute to the construction of an extravehicular activity (EVA) pressure garment. His research would help develop space suits that can be custom-fitted to astronauts while still being mobile, ergonomic, efficiently made, and cost-effective.
Daniel Varnum-Lowry is a Masters student in Aerospace Engineering at Texas A&M University. He is from Washington State and is interested in manned spaceflight and space exploration. Daniel’s work focuses in partial gravity fluid physics, particularly in experimental design and prototyping for the various research projects in the lab. After graduation, he anticipates entering the aerospace industry to support space exploration, especially for untouched regions such as Mars. When not in classes, Daniel can be found biking, skiing, and fishing.
Lexi Heinimann is a Masters student in Aerospace Engineering at Texas A&M University. She is from New Alexandria, Pennslyvania, and is interested in human spaceflight support systems. Lexi’s current work includes researching the effects of microgravity on the human thermoregulatory system which will be used to redesign the liquid cooling and ventilation garment (LCVG). After graduation, she anticipates working in the aerospace industry working on supporting human spaceflight. Outside of her studies, Lexi enjoys spending time with her dog and practicing archery.
Patrick Chapates is a Masters student in Aerospace Engineering at Texas A&M University. He is from Allen, Texas, and is interested in human systems integration, structural design, high-performance computing, and ECLSS design. Patrick’s current work in the lab includes glovebox design and development as well as digital scanning and 3D printing. Additionally, he is developing a Finite Element Model to study the interaction between the human hand and extravehicular activity (EVA) glove. After graduation, he plans on entering the industry as an environmental control and life support systems (ECLSS) or structural design engineer. Outside of his studies, Patrick enjoys the being in the outdoors, including mountain biking and sailing.
Callen Hajda is an undergraduate majoring in Aerospace Engineering at Texas A&M University. He is from Georgetown, Texas and is fascinated with human spaceflight and exploration. Working primarily with Dillon, Callen’s work focuses on spacesuit prototyping, specifically in developing a program to accurately predict the measurements of a suit based on the measurements of the person that would wear it. After graduation, Callen plans to attend graduate school or immediately enter the workforce to help advance human exploration and discovery of our solar system for the benefit of all.
Alan Cummins is an undergraduate student majoring in Aerospace Engineering at Texas A&M University. He is from Missouri City, Texas and is interested in human spaceflight operations and aerospace systems engineering. Alan’s work focuses on using software to automatically register 3D human scans and assisting Dillon’s research. After graduation, Alan plans to either attend graduate school to further his studies or enter the aerospace industry. Outside of class and the lab, Alan enjoys building rockets, watching baseball, and playing games with friends.
