	Detailed investigations of chemical transformations provide insights on just how molecules may be converted into other structures. Through determinations of reaction rates, activation parameters, product distributions, kinetic isotope effects, definitions of reaction stereochemistry, and explicit analyses of complex kinetic situations, new data and specific tests of alternative mechanistic interpretations of archetypal thermal reactions lead to better understandings of just how they take place and stimulate theory-based efforts toward similar goals. » read more

	Interactions of biomolecules with light forms is a unifying theme for research in my group. Step-scan time-resolved FTIR spectra are used to examine dynamics of protein conformational changes, using a variety of biochemical modifications to aid in accounting for the observed spectra. We have also developed 20-micron-thick Ge waveguide biosensors for analyzing the membranes of individual living cells with IR spectroscopy. » read more

	From experimenting with organometallic molecules in bulk gases and molecular beams, to manipulating defect chemistry in solid transition metal oxides, to noninvasive spectroscopy of biological materials in vivo, Dr. Chaiken’s research is directed at improving our fundamental understanding of light and matter interactions while attempting to solve practical problems of importance. » read more

	The long-term objective of my group is to develop new methods for organic synthesis and apply these methods in the synthesis of complex molecules. Catalytic techniques are of special interest because catalysts for organic reactions are not limited to simple rate acceleration, but can be modified to control the relative and absolute stereochemistry of the reaction products. The development of new catalysts for organic reactions is therefore a major goal. » read more

	Research in my group focuses on the roles metal ions play in biology, medicine, and materials science. The overall goal is to develop research that offers a unique perspective between the disparate areas of biological chemistry and materials science. This is an exciting time for inorganic chemistry with more and more inorganic chemists utilizing the tools of molecular biology to study metalloproteins and with greater availability of cutting edge instrumentation such as Superconducting Quantum Interference Devices (SQUID). » read more

	The Ruhlandt-Senge group’s particular research interests lie in two distinct areas: the preparation of novel organometallic species with applications in polymerization and synthetic chemistry, and the development of novel source materials for MOCVD applications. Research methods in the laboratory include inert gas chemistry both on a Schlenk line and in the glove box, low temperature crystallography, ¹H and heteronuclear as well as temperature dependent NMR spectroscopy, IR spectroscopy, thermogravimetrical analysis, and more. » read more

	Control of molecular reactivity and physical properties allows the design and realization of materials with new and useful capabilities. Research in our group involves both fundamental studies aimed at developing such molecular control and more applied studies on electronic and optical materials. Projects include both conjugated organometallic complexes and liquid crystalline holographic materials. » read more

	The primary focus of our research program is organic synthesis including the development of new synthetic methods and strategies, and their application to the asymmetric synthesis of natural products. Central to this program is the ability to prepare and characterize complex organic molecules. As such, students in the group are exposed to a broad range of synthetic, mechanistic, and spectroscopic techniques. Conformational analysis and molecular modeling studies also contribute to these activities. » read more

	My research group integrates organic chemistry, materials science and biology to address both fundamental problems and applications. Three intertwined approaches involve development of new organic reactions, supramolecular assembly and building nanostructured materials and surfaces. Examples include folding of designed molecules, organic nanocages, cell adhesion and migration and development of anti-thrombotic agents. » read more

	Platinum drugs are in wide clinical use for the treatment of various forms of cancer. We recently found that platinum drugs react with carbonate which is found in blood and the cell to produce hitherto unreported carbonato compounds that can attack the cell and react with DNA. The finding that carbonate is important in the mechanism of action of these drugs has overturned years of thinking on how the agents work and it will help stimulate the search for new and more effective platinum compounds for treating cancer. » read more

	My major current research area involves the application of vibrational inelastic neutron scattering and modern periodic Density Functional Calculations to problems involving the structure and dynamics of molecular crystals. Projects of primary interest include crystal polymorphism, short strong hydrogen bonds and the determination of molecular structures for crystals that do not diffract. In a collaborative research project with the Borer Laboratory, fluorescence methods and nucleic acid conformational equilibria are combined to detect nucleic acid/protein interactions. Our project includes application of this methodology in drug discovery and environmental detection of pathogens.» read more

	I have been involved in analyzing and interpreting HSQC NMR measurements, UV spectra, oxygen consumption curves, and other experiments on leukemia and other cells which have been exposed to anticancer drugs. The long-range goal is to construct a model for how the drugs enter cells, how they react with intracellular thiols, how the drugs attack nuclear DNA, and how the lesions on DNA lead to cell death. Understanding how killing of normal and cancer cells depends on extracellular drug concentration and exposure time should suggest new dosing protocols designed to destroy more cancer cells while lowering side effects.» read more
