Marcelo Davanco (Fed)

Marcelo Davanco is a Project Leader in the NIST Microsystems and Nanotechnology Division. His current research interests are in the design, fabrication and characterization of integrated photonic interfaces to single solid-state quantum light emitters, towards applications in quantum information science and technology.

He has co-authored over 60 journal papers and two book chapters, holds two patents, and has made many contributions to a wide range of research topics, such as photonic crystals and metamaterials, heterogeneous integrated photonic devices, integrated nonlinear optics and cavity optomechanics, and on-chip integrated quantum light emitters.

Marcelo has B.S. and M.S. degrees in Electrical Engineering from the State University of Campinas (UNICAMP), Brazil, and a Ph.D. in Electrical and Computer Engineering from the University of California Santa Barbara in 2006.
