Deborah S. Jin (November 15, 1968 – September 15, 2016) was an American physicist and fellow with the National Institute of Standards and Technology (NIST); Professor Adjunct, Department of Physics at the University of Colorado; and a fellow of the JILA, a NIST joint laboratory with the University of Colorado. She is considered a pioneer in polar molecular quantum chemistry. From 1995 to 1997 she worked with Eric Cornell and Carl Wieman at JILA, where she was involved in some of the earliest studies of dilute gas Bose-Einstein condensates. In 2003, Dr. Jin’s team at JILA made the first fermionic condensate, a new form of matter. She used magnetic traps and lasers to cool fermionic atomic gases to less than 100 billionths of a degree above zero, successfully demonstrating quantum degeneracy and the formation of a molecular Bose-Einstein condensate. Deborah Jin died of cancer on September 15, 2016. Born in Santa Clara County, California, Deborah Jin graduated from Princeton University in 1990 and received her doctoral degree in physics from the University of Chicago in 1995 with Thomas Felix Rosenbaum as her doctoral thesis advisor. Deborah Jin was an elected member of the National Academy of Sciences (2005) and Fellow of the American Academy of Arts and Sciences (2007).
