The C−C coupling of two molecules with a ferrocene 1,1′-diamide ligand
Dr. Diaconescu investigates The C−C coupling of two molecules of 1-methylbenzimidazole, effected by a neutral uranium dibenzyl complex and supported by a ferrocene 1,1′-diamide ligand.
The Theory and Computation Group in molecular and biochemical sciences at UCLA has been formed to bring together scientists who are developing and applying computation and simulation for the solutions of chemical and biological problems.
Theory, mathematics, and computation comprise a fundamental research core of physical and life sciences, and UCLA excels in all areas, from quantum and statistical mechanics through bioinformatics.
The Theory and Computation graduate program involves training in the whole broad field, but also concentration on research on one of the forefront fields of theory and computation.

Professor Anastassia N. Alexandrova
and her group work on theory and computation of materials, ranging from novel catalytic interfaces to artificial enzymes, and to small clusters in the gas phase and variety of other contexts. The group explores the last frontier of inorganic chemistry, in terms of their electronic structure and chemical bonding. They also develop new computational methods for multi-scale modeling of complex materials in realistic conditions relevant to their use in technology,

designs metal complexes supported by ferrocene-based chelating ligands. All projects under investigation harness ferrocene’s unique electronic properties to impart unusual reactivity in the activation of small molecules and to generate biodegradable polymers.
The Diaconescu group
Professor David S. Eisenberg
focus on protein interactions. In their experiments they study the structural basis for conversion of normal proteins to the amyloid state and conversion of prions to the infectious state. In bioinformatic work, they derive information on protein interactions from genomic and proteomic data, and design inhibitors of amyloid toxicity.

Professor William M. Gelbart
directs a research program, with Professor Charles M. Knobler, which features the interplay between a range of theoretical and experimental approaches to elucidating the physics of viral infectivity. Differences between the life cycles of DNA and RNA viruses -- in particular, how their genomes are packaged into and released from virus particles -- are investigated in terms of the differences between DNA and RNA molecules as physical objects. The tools and methods range from the statistical mechanics of simple models to in vitro systems consisting of a few purified components and to cell culture studies.

Professor James K. Gimzewski
focuses on nanoscale science and technology with an emphasis on mechanics on the nanoscale. His research consists of: (1) Nanomechanical dynamics and nanoarchitechtonics of living cells. This work is related to cancer, the action of drugs, environmental factors and other mutations in individual cells. His research pioneers the role of mechanics and cellular motion with the aim to develop new forms of medical diagnoses at the single cell level. (2) Use of biochemistry and AFM to gene profile DNA on the single molecule level. (3) Production of compact high energy beams of neutrons, photons, ions, and electrons using point source emitters coupled with piezoelectric and pyroelectric effects.
