Andrea Alù, Ph.D.

  • Director, Photonics Initiative
  • Einstein Professor of Physics, The Graduate Center, CUNY
  • Professor of Electrical Engineering, The City College of New York

Andrea Alù is best known for his breakthroughs in invisibility cloaking, or making objects transparent to incoming microwave signals. He realized the first freestanding three-dimensional invisibility cloak. He also developed the first nonreciprocal acoustic circulator—or one-way sound device.

Alù’s discoveries in metamaterials and plasmonics have broad implications for a range of sectors, including defense, communications, medical imaging, acoustics, mechanics, and robotics.

He joined CUNY and the Advanced Science Research Center from the University of Texas at Austin where he was the Temple Foundation Endowed Professor #3 in the Cockrell School of Engineering. He was also a member of the Cockrell School’s Wireless Networking and Communications Group and the head of the Metamaterials and Plasmonic Research Laboratory.

Alù is a recent recipient of the Alan T. Waterman Award (2015) from the National Science Foundation, one of the top prizes for scientists and engineers in the United States. He has three times been named a finalist for the Blavatnik National Awards for Young Scientists (2016, 2017, and 2018), the world’s largest unrestricted prizes for early career scientists.

He is a fellow of the Optical Society of America (OSA), the Institute of Electrical and Electronics Engineers (IEEE), the American Physical Society (APS), and the International Society for Optics and Photonics (SPIE). He is also a Simons Foundation Investigator in Physics and a distinguished lecturer for the IEEE Antennas and Propagation Society and the OSA.

Alù holds more than a dozen patents and patent applications and has co-authored more than 500 frequently cited contributions to scientific literature. He serves on the editorial boards of several international journals, including Physical Review B, New Journal of Physics, and Advanced Optical Materials. He has a Ph.D., M.S., and an undergraduate degree from the University of Roma Tre in Rome, and he conducted his postdoctoral research at the University of Pennsylvania.
