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 nature of electrons inside quantum materials and devices and develops tools for the manipulation of biological systems.
The group has developed a liquid-helium cooled scanning probe microscope (SPM) that can image ballistic electron motion through graphene and other 2D materials, and the two-dimensional electron gas in GaAs/AlGaAs heterostructures. In graphene they have imaged the electron cyclotron orbit in the magnetic focusing regime, characterized narrow ballistic electron beams produced by collimating contacts, and visualized Andreev reflection of electrons from a superconducting contact. Using the SPM tip as a movable gate, they can tune few-electron quantum dots and do Coulomb blockade spectroscopy of their quantum levels. 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 partnerships at Howard University, MIT, and the Museum of Science, Boston. The vision of the Center is to create quantum sensors, quantum networks, and quantum computers based on quantum materials, including graphene and 2D materials, 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 and for industrial research.
