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. Much of his current work at NIST is done in collaboration with Chemical Sciences Division colleagues Dr. David A. Long and Dr. Joseph T. Hodges.
Dr. Fleisher is an active member of the Optical Society (OSA). He currently serves on the CLEO Science & Innovations Active Optical Sensing sub-committee and the Fourier Transform Spectroscopy organizing committee. As an executive committee member of the OSA Environmental Sensing Technical Group, he organized and co-chaired the Incubator on Precision Measurements in Air Quality Monitoring held in Washington, DC. He is also a member of the ACS, APS, and AAAS.
