The research interests of this laboratory are aimed at the investigation of biological processes involving the synthesis, modification, storage and degradation of certain peptides and proteins using modern mass spectrometric methods of analysis to follow molecular events. In recent years there has been a great amount of interest in investigating the biochemical events involved in the metabolism of peptides, primarily in the brain and gut of mammals, encompassing the enzymatic breakdown of these peptides, their production from peptide and protein precursors, and the disruption of these processes by certain xenobiotics. Modern mass spectrometric techniques are used in these studies, including electrospray and matrix-assisted laser desorption ionization mass spectrometry.

The Zwier group focuses on problems at the interface between the traditional fields of molecular spectroscopy and dynamics. We develop and apply laser-based methods to study neutral molecules, ions, radicals, and molecular clusters of a size and complexity that test the large-molecule limits of current theories of chemical structure and dynamics.
Our current research interests have applications in the following three areas:
1. The investigation of conformational preferences, isomerization dynamics, and hydrogen bonding in biologically relevant neutral molecules, molecular ions, and molecular clusters. A particular current interest is synthetic foldamers, molecules designed to fold in well-defined ways that either mimic or complement the folding propensities of α-peptides found in nature.
2. The study of the photo-induced and discharge-driven chemistry and spectroscopy of molecules of importance in planetary atmospheres, particularly on Titan, one of the moons of Saturn.
3. The study of the chemistry, spectroscopy, and isomerization of molecules and radicals of importance in combustion, seeking to understand reactions and energy flow in aromatic derivatives that are intermediates along the pathway towards soot formation.

Research in our group is inherently multidisciplinary; we combine tools from chemistry, optics, biology, and microscopy to develop new approaches to probe dynamics. We study dynamics in two classes of systems: biological and bio-inspired light-harvesting systems that are of interest to solar energy research and biomass production; and bacterial and mammalian receptor proteins that are targets for human therapeutics. To explore these systems, we use ultrafast transient absorption spectroscopy, single-molecule fluorescence spectroscopy, and develop model membrane systems.

Recent innovation in mass spectrometry (MS) is the ability to generate intact molecular ions, focus and use them as ordinary reagents for organic reactions at ambient surface, outside the mass spectrometer. Most projects in the Badu lab build on this innovation, but instead of simple organic compounds, we focus on drugs and biomolecules of specific biological importance.

The long-term goal of our research is to understand the structural and dynamic information encoded in the linear sequence of amino acids. Proteins undergo an incredible transformation from one-dimensional sequence information into complex three-dimensional shapes that carry out intricate cellular functions. We still, however, don't have enough biophysical knowledge to translate this sequence information into functional insights. For instance, many proteins share the same native structure yet their cellular dynamics and function, in other words their energy landscapes, are different. Our laboratory uses a combination of biophysical, structural and computational techniques to understand these features.

Research in the Dyer group spans a broad range of problems in biophysical and bioinorganic chemistry. Links to the three main focus areas are included below: mapping protein folding energy landscapes, exploring the role of protein dynamics in enzymatic catalysis, and developing photocatalysts for solar water splitting and hydrogen production. We have also undertaken a collaboration with the Salaita lab, funded by DARPA, to exploit coupled enzymatic reactions for induced mechanical work.
Two unifying themes of this work are exploring the role of dynamics in protein structure and function and the development and application of new laser and spectroscopic tools for the study of protein dynamics. Our work effectively cuts across traditional disciplines with an emphasis on using quantitative physical methods to address biological problems. For example, our study of fast events in protein folding integrates efforts in mechanical engineering (microfluidics for ultrafast mixing), physical chemistry (spectroscopy, fast kinetics, physical models), molecular biology (mutants, protein folding models) and theoretical chemistry (MD simulations of folding). We emphasize the use of spectroscopic techniques with high structural specificity and time resolution, such as isotope edited infrared spectroscopy to elucidate the functional dynamics of proteins on all relevant timescales.

Our research focuses on developing and applying state-of-the-art single-molecule methods to characterize and understand the properties of nanoscale materials and biological systems. Compared with traditional ensemble measurements, the single molecule approach removes ensemble averaging, so that distributions and fluctuations of molecular properties can be characterized and transient intermediates identified. The single-molecule techniques we employ include single-molecule fluorescence imaging, single-molecule FRET, single-molecule tracking, super-resolution localization microscopy, and magnetic tweezers. Our research program provides students with scientific training spanning from sophisticated microscopy/spectroscopy techniques, rigorous data analyses to protein and genetic engineering using modern molecular biology techniques, as well as nanotechnology and nanomaterials.

Research in the Yates lab is focused on the development and application of mass spectrometry-based proteomics techniques to a wide range of biological questions. Our lab has been instrumental in the evolution of the field to its current status, having pioneered many of the landmark advances that form the basis for prevailing proteomics practices, including shotgun proteomics (McCormack, A. L.; Schieltz, D. M.; Goode, B.; Yang, S.; Barnes, G.; Drubin, D.; Yates, J. R., III. Anal. Chem. 1997, 69, 767−776), database searching (SEQUEST, Eng, J. K.; McCormack, A. L.; Yates, J. R., III. J. Am. Soc. Mass Spectrom. 1994, 5, 976−989), and Multidimensional Protein Identification Technology (MudPIT, Washburn, M. P.; Wolters, D.; Yates, J. R., III. Nat. Biotechnol. 2001, 19, 242−247). We continue the drive to increase the scope, sensitivity and throughput of proteomics technologies and their application to biological questions.
Our research encompasses the areas of bioinformatics and software development, methods development and biological applications. The integration of all the elements in the proteomics pipeline within one lab facilitates advances in all of them.
The Yates lab has published more than 700 peer reviewed papers. Recent highlights include comprehensive proteomics studies revealing molecular mechanisms implicated in Cystic Fibrosis as well as identification of proteins capable of restoring function to mutated proteins in the disease, and investigations into affective disorders of the brain, including schizophrenia and depression.

Cui Lab: When the size of materials is reduced to the nanoscale dimension, physical and chemical properties can change dramatically. In addition, nanostructures also afford new exciting opportunities of low-cost processing. We are interested in a broad range of nanoscale properties including electronic, photonic, electrochemical, mechanical, catalytic and interfacial properties. Understanding these properties has important technological implications in energy conversion and storage, electronics, biotechnology and environmental technology. We study fundamentals of nanomaterials including nanowires, colloidal nanocrystals and patterned nanostructures, develop low-cost processings and address critical issues in real-world applications.

My current work focuses on ratchets – far-from-equilibrium devices that transport particles using local asymmetries, rather than overall biases. Ratchets are rectifiers – they extract directional motion from non-directed sources of energy, like chemical energy and Brownian motion. Biological motors in the body use ratchet mechanisms, and produce motion very efficiently, even in the highly-damped biological conditions, where the noise is actually orders of magnitude stronger than the chemical energy available. We want to understand how the ratcheting applies to electrons, especially under highly-damped conditions, like in low-mobility organic semiconductors. Very little experimental work has been done on electron ratchets, and so we mainly seek to improve our understanding of the mechanism, with an eye toward possible future applications in solar cells or other electronic devices.
