Marcelo Davanco (Fed)

Marcelo Davanço is a Research Scientist in the Microsystems and Nanotechnology Division. He has B.S. and M.S. degrees in Electrical Engineering from the Universidade Estadual de Campinas (UNICAMP), Brazil, a Ph.D. in Electrical and Computer Engineering from the University of California, Santa Barbara, and was a Postdoctoral Research Fellow at the University of Michigan and then also at the CNST Nanofabrication Research Group. Marcelo has worked on a variety of topics related to the field of nanophotonics: InP-based photonic integrated circuits and photonic crystals, optical metamaterials, organic microcavities with strong exciton-photon coupling, hemispherical organic focal plane arrays, quantum-dot based single-photon sources, nonlinear integrated photonic devices, and nanophotonic cavity optomechanical systems. He is currently working with CNST researchers and external collaborators in developing measurement and fabrication techniques to advance the application of nanophotonics in sensing, imaging, and future electronics.
