[2] She worked at the Quaternary Isotope Lab at Washington from 1977 to 1998, after which she moved to Queen's University Belfast for a Postdoctoral fellowship in 1998–2001.

INTCAL provide (regular-updated) internationally-agreed radiocarbon calibration curves for the Northern and Southern Hemispheric Atmosphere (denoted IntCalXX and SHCalXX), and the global surface oceans (MarineXX), where XX denotes the year in which the update was provided.

These calibration curves enable consistent and comparable radiocarbon dating across the life and environmental sciences.

[11] The advances provided by these curves have extended radiocarbon calibration to the technique’s limit 55,000 years ago.

[16] In July 2022, she was appointed as Honorary Officer of the Order of the British Empire (OBE), for "services to Radiocarbon Dating, Calibration and Chronology".
