Robert Westervelt received his Ph.D. from the University of California, Berkeley in 1977. Following a postdoctoral appointment at Berkeley, he moved to Harvard University, where he is the Mallinckrodt Professor of Applied Physics & Physics. He is a Fellow of the American Physical Society.
Westervelt's group investigates the quantum behavior of electrons inside nanoscale structures and develops tools for the manipulation of biological systems.
The group has developed liquid-helium cooled scanning probe microscopes (SPMs) that can image electron motion through a two dimensional electron gas, in GaAs/AlGaAs and graphene/hBN layered structures. They visualized interference fringes and the pattern of flow of electron waves from a quantum point contact, made an imaging electron wave interferometer, and imaged magnetic focusing in GaAs/AlGaAs, and they have imaged the electron cyclotron orbit in graphene/hBN structures. Using the SPM tip as a movable gate, they can tune few-electron quantum dots formed in GaAs and an InAs nanowires. In previous research, they developed double and triple quantum dots in GaAs that act as artificial molecules.
On the bioengineering side, Westervelt's group has developed hybrid Integrated Circuit / Microfluidic chips - programmable microfluidic systems that can trap, move, sort, and assemble biological cells and small particles in fluids.
Robert Westervelt is Director of the NSF Science & Technology Center for Integrated Quantum Materials (CIQM) based at Harvard, with partners at Howard University and MIT. The Center develops new materials, devices and systems based on three types of quantum materials: atomic layers such as graphene, topological insulators, and nitrogen vacancy (NV) center diamond. Westervelt is Director of the Center for Nanoscale Systems (CNS) at Harvard University. CNS provides shared facilities for Nanofabrication, Electron Microscopy, and Materials Growth. CNS serves as a site of the NSF National Nanofabrication Coordinated Infrastructure (NNCI) that provides CNS facilities to students and faculty at other schools.
