Dawn Angela Shaughnessy is an American radiochemist and principal investigator of the heavy element group at the Lawrence Livermore National Laboratory.[3] She was involved in the discovery of five superheavy elements with atomic numbers 114 to 118.[1]
Shaughnessy wanted to be a doctor as a child but became interested in science at middle school[4] and studied at El Segundo High School.[5] She earned her bachelor's in chemistry at the University of California, Berkeley, in 1993.[6] She joined Darleane C. Hoffman's group for her doctoral studies, and completed her PhD[2] at the UC Berkeley College of Chemistry in 2000.[7][8] Her thesis investigated the delayed fission of einsteinium.[2][6] She won an award recognising her strength in graduate instruction.[6]
Research
Shaughnessy joined the Lawrence Berkeley National Laboratory in 2000, working under Heino Nitsche.[6] As part of a United States Department of Energy effort to clean up nuclear materials in the environment, Shaughnessy studied how plutonium interacts with manganese-bearing minerals.[6] She joined the Lawrence Livermore National Laboratory in 2002.[4]
In 2012 her group received a $5,000 grant which they donated to the Livermore High School department of chemistry.[7] She was appointed group leader of the experimental nuclear and radiochemistry group in 2013.[9] She has been involved in campaigns to celebrate Women's History Month.[10] In 2014 she was an editor of the book The Chemistry of Superheavy Elements.[1]
While leading the heavy element group, Shaughnessy partnered with the Joint Institute for Nuclear Research; the team managed to identify five new superheavy elements.[11][12][13][4] The elements were confirmed by the International Union of Pure and Applied Chemistry (IUPAC) in January 2016.[14][15] As they were discovered at the Livermore lab, she named element 116 Livermorium.[16] Her recent work has included nuclear forensics – being able to identify the traces of fissile material, products, and activation products after an explosion.[17][18] Her team are trying to automate sample preparation and detection, allowing them to speed up their isotope analysis.[18]
Awards and honors
Shaughnessy has won numerous awards and honors including:
- 2010 - Department of Energy Office of Science Outstanding Mentor Award[19]
- 2010 - Gordon Battelle Prize for Scientific Discovery[20]
- 2012 - Inducted into the Alameda County Women's Hall of Fame[21][22]
- 2016 - Fast Company Most Creative[23]
- 2018 - Elected a fellow of the American Chemical Society[18]
