The central theme of my research is to understand the chemistry and biology of peptides and proteins and to develop new approaches for manipulating these properties with purposefully designed small organic molecules. We employ chemical synthesis and combinatorial chemistry as well as spectroscopic, biophysical, and computational methods to accomplish these aims. Project includes:

• Rational design of small organic molecules for mimicking protein secondary structures
• Inhibition of key protein-protein interactions in various cancer models

Most of the research in our lab involves nanoporous metal oxides, which includes zeolites and related molecular sieves as well as metal-organic frameworks. Projects include the preparation, modification and application of molecular sieves in areas ranging from catalysis to membranes. Supported catalysts and host/guest materials include immobilized enzymes. Pulsed laser deposition and electrostatic deposition are used to prepare molecular sieve films and fibers respectively as part of an effort in membranes for gas separations, photovoltaics, supercapacitors, fuel cells, and drug delivery.

My research program is focused on developing molecular approaches to identify the cellular sources, targets, and physiologies of biologically relevant anions, which have been overlooked, in large part, from the chemical biology/bioinorganic perspective. We aim to not only define the molecular criteria required for aqueous anion detection, a long-standing challenge in molecular recognition, but will also make fundamental contributions to understanding the roles of anions in biological systems with applications in the development of diagnostics and treatment of associated diseases. To achieve these goals, we employ techniques in synthetic chemistry, protein engineering, spectroscopy, molecular and cellular biology, and bioimaging.

In molecular simulation research powerful computers are used to accurately model real systems using statistical mechanics and quantum mechanics. This provides a sort of “virtual laboratory” in which almost any property can be measured or examined, including those which are not accessible to experiments. We use simulations to develop an atomic-scale understanding of the behavior of complex systems. We are currently working on:

• Multi-scale modeling of amorphous porous materials, in particular silica aerogels and gel-based composites
• Development of new models for metals and ceramic materials
• Prediction and understanding of the properties of metallic glasses using simulations
• Simple models for understanding and controlling self-assembly
• Understanding phase transitions in confined systems
• New methods for molecular simulations, including advanced Monte Carlo algorithms and robust techniques for locating phase transitions.

• Electronic materials with an emphasis on dielectrics (low-K, high-K, and gate dielectrics other than SiO 2)
• Field emission materials, thin-film getters, and spacer materials
• Organic electronics

Neurofibrillary tangles (NFTs) are one of the two hallmark lesions of Alzheimer’s disease (AD) and their accumulation has been used to assess the severity of the disease. They are composed of paired helical filaments (PHF), a form of amyloid resulting from the aggregation of the microtubule-associated protein tau. Our laboratory has found that peptides as short as 3-6 amino acids are able to initiate the formation of twisted filaments, similar to PHF. We believe that these short amyloid-forming peptides provide an excellent model for studying the structural basis of PHF and amyloid, in general. By understanding the structural basis for amyloid formation, a rational design of therapeutic agents able to prevent PHF accumulation can be undertaken. In addition to using short tau-related peptides to understand the basis of amyloid formation, they may be used as targeting agents for amyloid. For example, we have recently shown that contrast agents prepared from these peptides and a gadolinium chelate bind strongly to senile plaque and NFTs and may act as MRI probes for the diagnosis of AD.

Work in the Novak Group has focused on the synthesis and properties of a unique family of helical macromolecules, the polycarbodiimides. Inspired by the helices of nature, these polymers display unusual properties including antimicrobial activities, liquid crystallinity, and act as chemical sensors, tunable polarizers, and optical switches. Polycarbodiimides are prepared through a metal catalyzed polymerization of carbodiimides. When chiral catalysts are used, helical polymers with a single screw-sense are produced that display unusual chiro-optic properties including reversible optical switching. Beauty and function.
