David Waldeck
Chemistry and Dynamics in the Condensed Phase. Professor Waldeck's research program uses methods of spectroscopy, electrochemistry, and microscopy to investigate primary processes in the condensed phase, which includes liquids, solids and liquid/solid interfaces. Current themes of his research are the fundamental understanding of electron transfer reactions, electron transport in supramolecular structures, and nanophotonics.
Solution Studies. His research program studies electron transfer processes experimentally in order to directly evaluate and improve theoretical models. Currently, his group is investigating how the electron transfer rate in semiconductor nanoparticle assemblies depends on energetic, geometric, and electrostatic features of the assemblies. Other efforts are studying electron transfer between semiconductor nanoparticles and conjugated polymers and how it depends on the energetic, electrostatic, and chirality of the constituents. A major goal of these studies is to understand how the structural and energetic hierachy of nanometer scale assemblies can be manipulated to control the electron transfer.
Interfacial Charge Transfer. This effort probes charge transfer through monolayers and individual molecules by electrochemical and/or conducting probe methods. Previous work has used electrochemical studies to elucidate how the molecular properties (e.g., electronic character, chirality, and the nature of the molecule-electrode linkage) affect the observed tunneling barriers and molecular conductivities. Current work is investigating how to manipulate the electronic and chemical nature of monolayer films to enhance the electronic interaction between a redox moiety and the electrode, with a particular focus on better understanding how to ‘wire’ biomolecules (proteins and oligonucleotides) to electrodes.
Nanophotonics. Technological breakthroughs in fabrication and characterization are allowing his group to probe the nature of light-matter interactions (photonics) for nanostructures and molecular assemblies. This work aims to develop a better understanding of the novel optical properties displayed by nanostructures and how to exploit them for applications in sensing and energy conversion.

Quantum information is a rapidly growing theoretical and experimental field which seeks to harness the complexity and coherence of quantum bits to address challenges in computation and the simulation of complex quantum systems. My research focuses on the use of superconducting microwave circuits as a quantum information platform. In particular, we will focus on the use of microwave photons as quantum information carriers. We will develop techniques to create, manipulate, and measure microwave light and use it to entangle larger quantum systems.

David Snoke received his B.A. in Physics from Cornell University and his Ph.D. also in Physics from the University of Illinois at Urbana-Champaign. Upon graduating, he moved to Stuttgart, Germany where the spent the next two and a half years as a Postdoctoral Fellow at the Max Planck Institute, one and a half years of which were as an Alexander von Humbolt Fellow. He then became a member of the technical staff of The Aerospace Corporation before finally joining the Department of Physics of the University of Pittsburgh in 1994. He was elected a Fellow of the American Physical Society in 2006.
