Ana de Bettencourt-Dias

Susan Magee and Gary Clemons Professor of Chemistry she/her/hers

Summary

Ana de Bettencourt-Dias received her ‘licenciatura’ (MS equivalent) in Technological Chemistry from the University of Lisbon in 1993, and her ‘Dr. rer. nat.’ (PhD equivalent) in Inorganic Chemistry from the University of Cologne in 1997 with Prof. Thomas Kruck. In her graduate work, she isolated new titanium complexes as single source precursors for the chemical vapor deposition of TiN thin layers. She joined the group of Prof. Alan Balch at UC Davis in 1998 as a Gulbenkian postdoctoral fellow, where she studied the electrochemistry and structure of fullerenes and endohedral fullerenes. In 2001 she joined the faculty at Syracuse University and started her work on luminescent lanthanide ion complexes. She moved to the University of Nevada, Reno, as associate professor in 2007 and was promoted to professor in 2013. Her research centers on light-emitting compounds and coordination chemistry of the f block of the periodic table. She served on the editorial advisory board for Inorg. Chem. from 2013 to 2015, and has been a managing member of the editorial board of the Journal of Rare Earths since 2014. She was program chair of the 2011 and conference chair of the 2014 Rare Earth Research Conference, organizes the lanthanides and actinides symposia at the national meetings of the American Chemical Society and was the 2019 Chair of the Division of Inorganic Chemistry of the American Chemical Society. She served as the Associate Vice President for Research at UNR from 2015 to 2019. She returned to being a full-time faculty in July 2019, and is now the Susan Magee & Gary Clemons Professor of Chemistry.

About the Susan Magee and Gary Clemons Professorship
