Allison Bolinger - Keynote Lecturer

Flight Director, NASA

Allison Bolinger grew up in central Ohio dreaming of one day working for NASA. With her sights set on the stars, she chose the Cradle of Astronauts as her launch pad. While studying Aeronautical and Astronautical Engineering at Purdue, she participated in the cooperative education program and spent five tours at NASA’s Johnson Space Center in Houston, Texas. After graduating with her Bachelor of Science in 2004, she and her new husband, Jeremy (BS, Biology ’04), moved to Houston. She began her full-time career at NASA in the ExtraVehicular Activities (EVA) group, teaching astronauts to spacewalk and working in Mission Control while those spacewalks were executed. After 12.5 years in the EVA group supporting numerous Space Shuttle missions and International Space Station (ISS) expeditions, the last two years of which she served as the EVA Task Group Lead, she moved to the Neutral Buoyancy Lab (NBL). Her role as the NBL Deputy Chief included managing the daily operations of the 6.2 million gallon underwater EVA training facility. In June 2018, a dream was realized when she was selected as a Flight Director. After a little over a year of training, in October 2019, she was certified as the 95th Flight Director. She selected the call sign Athena Flight and has spent over 1,000 hours on console in Mission Control. As a Flight Director, Allison has been primarily focused on ISS, leading the 13th cargo resupply mission of the Northup Grumman Cygnus spacecraft in February 2020.

Kanika Gakhar - Keynote Lecturer

Propulsion Engineer, SpaceX

Kanika always found great pleasure in analogies. As a young dancer, she would position her center of mass to balance angular moments during her headstands and spins. As an undergraduate researcher at Texas A&M; and an avid fan of analogies, she researched the aeromechanics of natural flapping flight through the development of a hover-capable robotic hummingbird. Studying the vortices and unsteady flows associated with flapping flight motivated her to dive deeper into the generation of losses in complex propulsion systems. Consequently, she decided to pursue her masters in MIT’s Gas Turbine Lab (GTL). As an NSF and Whittle fellow in GTL, she aimed to make aircraft engines more efficient by studying the effects of combustor turbulence on high-pressure turbine performance. Currently, she continues to pursue her interest in the interaction of complex physical phenomena by working as a Propulsion Engineer at SpaceX. While she is excited and proud to be part of an industry that is revolutionizing life for humanity in space as well as on earth, her passion for leadership in service has led her to engage in multiple outreach, tutoring, and mentorship opportunities. She aims to dedicate her life to initiating change and pursuing advancement in both technology as well as society.
