Cytoskeletal Microtubules, Cell Cycle and Cancer
Cancer is a surreptitious killer that has touched all of our lives in one way or another. It is no wonder that the disease is described as the defining plague of our generation. Fortunately, decades of exhaustive research have yielded a battery of chemotherapeutic agents, the most notable of which include tubulin-binding drugs. Although these drugs can be effective to varying degrees in killing cancer cells, they are notorious for their debilitating, toxic side effects...

Cancer Immunology and Human Adenovirus Infection and Leukemia
My laboratory conducts research in the areas of tumor immunology, mechanisms of tumor cell/immune cell interactions, as well as investigating the association of human adenovirus with lymphocytes and leukemia. Ongoing studies involve (1) the analysis of basic anti-tumor immunologic mechanisms and principles, (2) analysis of tumor cell-immune cell interactions and (3) investigating the possibility that human species C adenovirus can initiate acute leukemia.

Research Interests: Active mucosal inflammation is characterized by influx of immune cells, especially neutrophils. When occurring in response to a pathogenic microbe, this immune inflammatory response appears to play an important role in locally clearing some infections thus preventing widespread bacterial dissemination in the host...

Microbial biofilms: understanding microorganisms attached to surfaces
The central focus of research in my laboratory is microbial biofilms, or communities of microorganisms attached to surfaces. Biofilms are widely distributed in nature, and may be beneficial or harmful to humans, depending on the microbes that inhabit them. A common feature to all of our work with biofilms is quantitative analysis of biofilm structure based on biofilms grown in flow cells and imaged by confocal microscopy...

Transcriptional Regulation of Neural Development
To develop normally, eukaryotic organisms must carefully orchestrate the processes of differentiation, morphogenesis, and growth through spatial and temporal regulation of gene expression. The bHLH transcription factor family regulates the expression of a number of genes that modulate development, often through regulatory cascades that rely on the proper responses to sensory signals provided by the environment...

Dynamic Regulation of Inflammation, Cell Surface Interactions and Signaling and Leukocyte Biology.
Inflammation is a vital host response that serves as a major immunological mechanism to protect the host from pathogens, irritators and transformed / altered self-cells. Acute inflammation generally involves sequential events of local cell response and production of inflammatory mediators, activation of endothelial vasculature, transmigration of large numbers of neutrophils into tissues, and the final stage of monocyte/macrophage-mediated clearance. When the inflammatory reaction lingers and becomes chronic, local macrophage response and neutrophil infiltration are also regulated by cytokines derived from activated dendritic cells and polarized T cells. Our recent studies focus on elucidating the dynamic mechanisms that regulate leukocyte response and neutrophil transmigration at different stages of inflammation.

The genome of viruses has a limited size that usually is only sufficient to encode a few viral proteins. To assemble a fully functional virion, the viral capsid applies simple symmetry to build the viral particle with multiple copies of the same protein subunit. This universal principle is found in virus structures through the entire virosphere...
