Matthew Y. Sfeir, Ph.D.

  • Associate Professor, Photonics Initiative
  • Associate Professor of Physics, The Graduate Center, CUNY

Matt Sfeir’s research focuses on enabling technologies for next-generation devices that leverage the unique optical properties of macromolecular and nanoscale materials. He is the author of more than 100 published papers, primarily concerned with using ultrafast laser techniques to identify interesting electronic properties and dynamical processes and to investigate their application in light harvesting and photonics applications. He has received numerous awards for his work, and in 2018 was named an Inventor of the Year by the global science and technology organization Battelle. He has served on several committees and advisory boards, including the executive committee for the Energy Subdivision of the American Chemical Society Division of Physical Chemistry, and he is a member of the editorial advisory board of Review of Scientific Instruments.

Matt joined the ASRC and The Graduate Center, CUNY from the U.S. Department of Energy’s Brookhaven National Laboratory where he was a member of the laboratory’s Center for Functional Nanomaterials. He received a B.S. degree from the University of Chicago in 2000 and Ph.D. degree in Chemical Physics from Columbia University in 2005. He subsequently conducted postdoctoral research at Brookhaven National Laboratory in the Condensed Matter Physics and Materials Science Department.
