In 1946, she moved on to the laboratory to take a position as a junior physicist. Over the years, she worked with such notable researchers as Alvin Weinberg, Art Snell, Walt Jordan, E. P. Blizzard, Larry Meem, Sam Beall and Doug Billington. She remained at ORNL and worked for Fred Maienschein until her retirement in 1961.
In 1953 she marrried Jack Estabrook.
- "Her relationship with the reactor was so novel that a separate graphite pile used for studies through the use of foils was called Pinky's Pile, so named because she had supervised the building of this small pile and because of her red hair." https://web.ornl.gov/info/reporter/no55/jan_feb04.htm
