Hwang was born in Taiwan on 21 July 1970. She moved with her family to the United States at the age of two. Most of her early education was in Texas.[1]
Hwang joined Wyle Laboratories in September 2001.[5] At first she worked as a scientist in the sensors group. This work included research for monitoring the health of cell cultures on the space shuttle or station. In 2002 she moved to the neurosciences group. This group studies the effects of space flight on astronauts, with a focus on helping them adapt to space and their return to Earth.[1][5] In 2011, Hwang moved to the Integrated Science & Engineering (ISE) group.[2]
