Adam Fleisher (Fed)

Dr. Adam J. Fleisher is a Research Chemist at the National Institute of Standards & Technology (NIST) in Gaithersburg, MD, USA. His research involves the development of advanced optical sensing techniques using optical frequency combs, quantum-cascade lasers, and high-finesse optical resonators. Prior to joining NIST, AJ Fleisher was a National Research Council (NRC) postdoc at JILA under the supervision of Jun Ye. He earned his Ph.D. from the University of Pittsburgh in 2011 while working under David Pratt, and completed his undergraduate studies at Elizabethtown College in 2007.

Dr. Fleisher is an Ambassador of the Optical Society (OSA), leading interacting with student chapters and mentoring other early-career professionals. He routinely serves on the organizing committees for several optical sensing and spectroscopy meetings, is the lead guest editor on two Joint Feature Issues of Optics Express and Applied Optics, and currently chairs the CLEO Science & Innovations Active Optical Sensing sub-committee. In 2019, he participated on the Consultative Committee for Amount of Substance:  Metrology in Chemistry and Biology (CCQM) Working Group on Isotope Ratios (IRWG) at the International Bureau of Weights and Measures (BIPM) in Sèvres, France.
