Research Interests
The embryos of higher plants must make a number of critical decisions that affect the way in which they develop. Normally, after morphogenesis is complete the embryo enters a period of maturation . However, mutations or laboratory conditions exist that interfere with the normal transition to a maturation program and, instead, cause premature germination. For several years I have studied the regulation of maturation-specific genes in a large-seeded legume (P. vulgaris). These studies have revealed that the information necessary to express genes during maturation resides within short DNA sequences acting as enhancer elements. Presently, my laboratory is investigating how embryonic cells decide which way to proceed (e.g. through the action hormones) and which signals control the function of maturation-specific transcription factors.

Research Interests
Research expertise is in the following areas:
This elementary metabolic pathway functions to chemically remove cytotoxic methylglyoxal that arises as an unavoidable by-product of normal cell metabolism. The pathway is of particular interest because one of the two enzymes in the pathway is deficient in cancer cells. From a basic science perspective, experiments are directed at examining both the kinetic and stereochemical properties of the glyoxalase enzymes that allow the pathway to operate at such a high level of efficiency in normal cells From a practical perspective, special glutathione derivatives have been synthesized as powerful inhibitors of the glyoxalase enzymes These compounds are the basis of a novel chemotherapeutic strategy that we are testing A second research interest is the synthesis and testing of special "mechanism based" inhibitors of HMG-CoA reductase which are designed to elucidate the stereochemical features of the active site. This work may provide a basis for the development of a new class of cholesterol-lowering drugs.

Current Research Interests
I am Interested in the nonlinear optical interactions of light and matter and the basic physical properties of organic materials and polymers used in the field of optical signal processing (optical interconnected pattern recognition, computing).
I am also interested in the mechanisms of photoconduction, photorefractivity, and optical storage in new class of materials - photorefractive polymers.
In addition to measuring the nonlinear optical coefficients of organic and polymeric materials photonic devices based on these materials are modeled, fabricated, and tested in my lab. Nonlinear optical (NLO) materials respond to external applied electric and optical fields by mixing them to create new fields and new frequencies (colors). Because of their low cost, high nonlinearity and flexible processing requirements NLO polymers are promising new materials for use in photonic systems. High speed optical modulators waveguide harmonic generators, reconfigurable optical interconnection media, and integrated optical switches have been demonstrated using these materials. Devices such as these will be required in future photonic based communication (fiber-to-the-home), computing (high-speed hybrid optical computers), and sensor systems ("smart"materials).

Research Interests
Interested in structure function studies on single strand specific nucleic acid binding proteins and on various nucleic acid polymerases.
The systems under current investigation in my laboratory include the heterogeneous ribonucleoprotein (hnRNP) Al. Several of the hnRNP proteins have recently been cloned and expressed, and we are elucidating their ribonucleic acid (RNA) binding properties and effects on RNA conformation, with the goal of better understanding their role in the processing of RNA. We are using a combination of methodologies: biophysical techniques (fluorescence and spectrophotometric) and chemical modification approaches. We have developed a number of unique methods, such as the labeling of helix destabilizing proteins (HDP) with a photoactive polynucleotide analog, which we hope will be of major value in the delineation of the nucleic acid binding site on the protein. In addition, we are studying various properties of the RNA binding proteins of retroviruses, with a view toward understanding the mechanism and specificity of viral assembly.
With the availability of recombinant wild type and mutant eukaryotic deoxyribonucleic acid (DNA) polymerases, we have begun to explore the nucleic acid and nucleotide interactive properties of these enzymes by techniques and approaches similar to those we are using with the binding proteins. Our objective is to correlate binding with catalytic properties, and to understand our observations within the contexts of the physiological roles and 3-dimensional structures of these enzymes.

Research Interests
New materials and new methods to prepare them are essential to virtually all aspects of technological development. More powerful computers require high quality semiconductor and magnetic storage media; new high temperature alloys and ceramics are the key to increase the efficiency of car and airplane engines. Many desirable properties are achieved by the application of metastable materials like metallic glasses and nanocrystalline materials.
Our current research interest is the application of high energy ball milling, a process called mechanical alloying or mechanochemical synthesis, to the preparation of novel materials. The unique feature of this process is that grain refinement, alloying, and chemical reactions take place at room temperature under far-from-equilibrium conditions. Investigations are under way to prepare nanocomposites for structural and magnetic applications. Typical systems consist of 10 nm iron particles in alumina or TaC particles in a TaNi alloy matrix.
We are also developing models to describe the mechanism of the ball milling process. This is a challenging task due to the complex combination of mechanical, chemical, thermal, and transport processes. We are especially interested in highly exothermic reactions where ball milling can initiate a self propagating thermal reaction. Mechanochemical reactions between a metal oxide and a more reactive metal and combination reactions to form carbides, borides, and sulfides are investigated. Our main experimental methods are X-ray diffraction, thermal measurements, and magnetic characterization.
