Bacterial Biofilms

Biofilms are microbial communities embedded in a self-produced extracellular polymeric matrix. It is now well recognized that cells undergo profound changes in the transition from free-living to matrix-embedded (biofilm) communities. An important characteristic of microbial biofilms is their innate resistance to immune system- and antibiotic-killing. This has made microbial biofilms a common and difficult-to-treat cause of medical infections. Several chronic infections have been shown to be mediated by biofilms such as the respiratory infections caused by Pseudomonas aeruginosa in the cystic fibrosis (CF) lung and Staphylococcal lesions in endocarditis. Biofilms are also a major cause of infections associated with medical implants mainly by Staphylococcus epidermidisStaphylococcus aureus, and P. aeruginosa. It has been estimated that 65% of the bacterial infections treated in hospitals are caused by bacterial biofilms. Thus, there is an urgent need to discover innovative treatments for biofilm-associated infections. The current understanding of how biofilms develop and how they acquire increased resistance is still in its initial stages. Our research focuses on understanding the basic aspects of the signals and processes involved in biofilm development with a goal of finding new methods of treating biofilm-related infections. The aims are:

1) To characterize how biofilms develop, with a focus on the role of iron as a signal in biofilm development.

2) To understand the mechanisms by which biofilms obtain increased resistance to antimicrobial therapy.

3) To understand the role of inter- and intra-species cell-cell communication in mixed species biofilm interactions.

4) To discover novel compounds that effectively eradicate biofilms.

We implement an array of physiological, biochemical, and genetic tools combined with novel technologies that allow controlled and reproducible biofilm growth to characterize bacterial biofilms and compare them to the non-biofilm communities.

Methods for preparing nanomatic materials

Sonochemistry, sonochemistry, the use of microwave radiation and a method called a rupture in which a part of a chemical laboratory becomes an autoclave.

We deal with a variety of uses of materials we have prepared.

Structural Studies of Cell Signaling Assemblies

We use structural and biochemical methods to study how cytokines activate receptors to initiate precise signaling events across the cell membrane. Receptor tyrosine kinases (RTKs) are key players in the control of a wide range of cellular processes including proliferation, differentiation, migration and survival. They are composed of an extracellular domain to which specific ligands bind, a single-pass transmembrane helix, and an intracellular tyrosine kinase domain flanked by regulatory regions. We seek to understand how the extracellular event of ligand binding to the receptor is translated into an accurate intracellular response. We are also interested in structural investigations of coordinated signaling through assemblies of RTKs and co-receptors. Through the parallel use of X-ray crystallography and single-particle electron microscopy, we address basic mechanistic questions concerning the early stages of cell signaling.

The study of the etiology of cancer is critical to understanding how to prevent this disease and to improve treatment. In addition to genetic and environmental factors, several viruses also can trigger the development of cancer.

Theory of strongly correlated electron systems, collective behavior in quantum phases and quantum criticality. In particular, my research interests focus on transport phenomena in low-dimensional systems: superconductivity in thin films and wires; superconductor-insulator transitions; spin, charge and heat transport in low-dimensional magnetic systems; quantum Hall effect in graphene.
