Improving catalysts could minimize the use of fossil fuels, thus helping solve the energy crisis while decreasing greenhouse gases. Our group tries to clarify why catalyst modifiers act to promote catalytic activity or selectivity, and how nanoscale features of the catalyst surface can tuned to make better catalysts. In solar cells and LEDs, charge injection and extraction occurs at the interface between a metal or other conductor and one of the semiconducting materials (inorganic materials in most current commercial devices, but hopefully cheaper-to-make polymer films in the future). We also study the energetics and electronic properties of these interfaces.

Most of our nano-objects are grown in our lab, and they are then built into various kinds of devices using micro- or nano-fabrication techniques. We are particularly interested in low-dimensional physics, many-body effects, phase transitions, and unusual electronic excitations. We work very closely with the Nanoscale Optoelectronics Lab of Professor Xiaodong Xu and exploit low-temperature expertise of Professor Oscar Vilches.

Applied research has focused on the use of inversion-based approaches to solve challenges in nano (and sub-nano) scale precision positioning needed in scanning probe microscopes such as the atomic force microscope (AFM) and the scanning tunneling microscope (STM). It is noted that the AFM and STM are key enabling tools in the nano area; therefore the current work aimed at increasing their throughput will have a significant impact on the real-time investigation and manipulation of nano-scale and sub-nano-scale phenomena. For example, the inability to precisely position an AFM probe (at high speed) over a cell surface has traditionally limited the ability to image time-varying dynamics of cellular processes. In particular, lack of precision positioning (due to movement-induced vibration) leads to excessive forces on the cell surface (as the probe digs into the cell) and causes sample damage. Therefore, current AFM imaging of cells is limited to low operating speeds. Our research group was the first to demonstrate (experimentally) that feedforward techniques can effectively compensate for movement-induced vibrations in Scanning Probe Microscopes. Thereby, we showed that feedforward inputs could be used to increase the operating speed of Scanning Probe Microscopes. See website for further information.

My research involves the study of bacterial communities. This research focuses on two aspects that are closely related. Quorum sensing is a term used to describe the regulation of gene expression according to population densities, many Gram-negative bacteria use specific signaling molecules, called acyl-homoserine lactones (acy-HSLs), to sense the presence of other bacteria of the same species in the bacterial cell membrane. At high cell densities the acyl-HSL reaches a critical concentration at which expression of quorum sensing-controlled genes is induced. Therefore, quorum sensing constitutes a rudimentary communication system between bacteria that allows them to coordinate behavior at the community level.

By integrating synthetic chemistry and physical chemistry approaches—including contributions to mechanistic molecular photochemistry, solid-state photophysics, and interfacial electrochemistry—to explore fundamental principles and dynamics relevant to solar photocatalysis, the Schlenker group works to design new scalable materials and devices to meet global sustainable energy challenges.
The formation and function of electrochemical materials and interfaces are critically affected by molecular adsorption and templating. Our group explores the use of engineered proteins as modifiers of nucleation and growth, as well as orchestrators of hierarchical structures. In separate efforts, we also explore innovative methods to convert waste materials, especially lignocellulosic feedstocks, into value added products.
We are interested in understanding how biological organisms process information using complex biochemical networks and how such networks can be engineered to program cellular behavior. The focus of our research is the identification of systematic design rules for the de novo construction of biological control circuits with DNA and RNA components. Our approach integrates the design of molecular circuitry in the test tube and in the cell with the investigation of existing biological pathways like the microRNA pathway. Engineered circuits and circuit elements are being applied to problems in disease diagnostics and therapy.
The Human Photonics Laboratory (HPL) works to advance the frontier of optical technology in the areas of human performance, cancer detection, and treatment.

My laboratory aims to decipher and manipulate the molecular mechanisms by which mammalian cells establish and utilize higher-order chromatin structures, with an emphasis on the interplay between noncoding RNAs (ncRNAs) and nuclear architecture. Towards this end, we are developing a suite of novel technologies for probing and exploiting ncRNA function in situ, including methods for targeting artificial ncRNA devices to chromatin. Combined with an array of biochemical, genomic, and chemical biological techniques, we aim to elucidate the mechanisms by which ncRNAs influence nuclear organization at all levels. This will enable new routes towards novel RNA-based and RNA-focused biotechnologies and therapeutics.
Our lab investigates how cells are influenced by mechanical interactions at the micro and nanoscale. To pursue these goals, we are developing new tools – micro- and nano-devices, quantitative image analysis, and computational models – that we use to understand the underpinnings of biomechanics and mechanobiology. The greater impact of our work is to delineate how cell mechanics affect cardiovascular disease and cancer in order to catalyze new strategies for their treatment. By working at the intersection of mechanics and biology, we are increasing understanding of the theories of soft, active, and multifunctional materials.
Professor Stahl’s group studies microbial community structure and function in many different habitats, including aquatic systems, extreme environments, animal guts, the human mouth, and contaminated systems.

Our goal is to hijack and rewire aspects of nature’s developmental programs to control the processes by which cells assemble to form human tissues. We are also working to develop technologies to remotely control these tissues after implantation in a patient. To do this, we use diverse tools from stem cell biology, tissue engineering, synthetic biology, microfabrication, and bioprinting. We seek to translate our work into new regenerative therapies for patients with heart and liver disease.

The Thomas lab studies regulated adhesive proteins. While we study protein allostery in general, we are particularly interested in mechanical regulation. A main interest is in “catch bonds” that are activated to bind by tensile mechanical force. In particular, we study mechanical regulation of proteins involved in bacterial infection and thrombosis. We also engineer smart regulated adhesives. In our “actibodies” project, we design activatable, antibody-like recognition proteins. In our “biocatch adhesion” project, we integrate catch bonds into adhesives that will allow medical robots to catch human tissue under force, and then release it, like nanoscale locking seatbelts.
The research in Dr. Traxler’s laboratory focuses on the genetic and biochemical analysis of protein folding and function. Recently, the lab has been involved in the development of materials for nanotechnology. Different proteins characterized in the lab’s genetic analyses are being engineered by the addition of polypeptide sequences that bind to various inorganic compounds. Those inorganic compounds can be arranged in predictable structures, based on the self-assembly properties of the substrate proteins. Examples include using different DNA binding proteins to organize inorganic nanoparticles along a DNA guide.
We are interested in probing the structures of membrane proteins and their complexes, and understanding the molecular basis of their biological functions. We have developed a novel and general method, called “random spherically constrained” (RSC) single-particle electron cryomicroscopy (cryo-EM), to study membrane protein structures in membrane environments. This method does not rely on crystallization, and it can be, in principle, applied to any membrane protein. It not only preserves the membrane protein’s integrity and native conformation, but also enables access to biologically interesting states.
The Woodrow Laboratory is focused on the applications of engineered biomaterials in mucosal infections and mucosal immunity. Our long-term goals are to design and build multifunctional materials that will: (1) lead to novel preventative strategies against mucosal infections, (2) program protective immune responses at mucosal sites of pathogen entry, and (3) facilitate studies of mucosal infections and mucosal immunity in health and disease. These scientific goals are addressed from the perspective of fundamental science, technology development, and translational research.
We use high resolution live imaging and total internal reflection microscopy to study molecular motors and their role in mitotic spindle assembly and chromosome movement. At the single molecule level we evaluate motor control of dynamic microtubule assembly and disassembly. Of special interest are the forces driving oscillatory chromosome movement, mitotic spindle assembly and mitotic spindle orientation in live cells. Finally, we are interested in the advection of motors in live cells. In other words, how the kinetic parameters of single microtubule motors influences their translocation, distribution and function in cells and we are interested in modeling this activity in silico.
