Early life and education edit

Murray studied chemistry at St. Mary's University in Halifax, Nova Scotia, Canada from 1985, graduating with a Bachelor's Degree with Honors in Chemistry in 1988.[6] He spent a year as a Rotary International Fellow at the University of Auckland in 1989. From 1990 he studied at the Massachusetts Institute of Technology (MIT), where he received his doctorate in chemistry in 1995.[7][6]

Career edit

From 1995 Murray worked at the Thomas J. Watson Research Center at IBM. From 2000 to 2006 he headed their Nanoscale Materials and Devices Department. In 2006 the University of Pennsylvania announced his appointment as the Richard Perry University Professor, with appointments in Chemistry and Materials Science, in the schools of Arts and Sciences, and Engineering and Applied Science.[8][7][6]

Research edit

Murray, David Norris and Manoj Nirmal were the first graduate students to work with Moungi Bawendi at MIT.[9] As part of his thesis work, Murray helped to develop synthetic methods for making quantum dots, including identifying a longer chain version of trioctylphosphine oxide as being cheaper and having additional benefits when used in synthesis. In 1993, Murray, Norris and Bawendi published a breakthrough paper describing the hot injection synthesis method for making quantum dots.[9] Both Murray's and Bawendi's contributions to the synthesis and characterization of semiconductor quantum dots were recognized by the American Chemical Society with its 1997 Nobel Laureate Signature Award.[7]

Their method was both adaptable and reproducible, making it possible to consistently synthesise monodisperse nanoparticles and develop large-scale applications using quantum dots.[9] Bawendi received the 2023 Nobel Prize in Chemistry for the development of this method.[10]

Much of Murray's has work focused on the synthesis and characterization of nanoscale materials, including nanoscale magnets, semiconductor nanocrystals, and nanocrystal superlattices. Murray was recognized at IBM as a Master Inventor and patent evaluator.[8] He holds at least 26 nanascale patents.[11][12]

Murray is concerned with the synthesis and self-assembly properties of nanocrystals and the potential to create new mesoscopic materials with interesting properties and potential applications in energy, environmental sustainability, health, and information processing.[11][7]

Murray is the Founding Chair of the World Economic Forum’s Global Councils on Nanotechnology (2008-2009) and Global Council on Emerging Technologies (2009-2010).[7]
