I am interested in cell biology, cancer cell biology, oncogenesis, "biomarkers", and mathematical modeling of cell process regulation.  Early work in the lab focused on cell immortalization through expression of SV40 large T antigen and development of cytometric methods to analyze the cell cycle.  Our present interests focus on analysis of cell signaling and the cell cycle by cell-based methodology, and mathematical modeling of the cell cycle and cell signaling.  The latter is in collaboration with Sree Sreenath (Computer Sciences and Electrical Engineering) and Tom Radivoyevitch (Epidemiology and Biostatistics).

We have two main enterprises in the lab: "multi-variate cell cycle analysis and modeling" and "measurement and analysis of cell signaling as a leukemia biomarker". There is a single overarching goal – to test the following set of ideas within the context of human disease: (1) multi-variate cytometric data, measuring key process-related epitopes, resolve to kinetic profiles of programmed gene expression, and (2) a series of bivariate views or a single N-dimensional view of these profiles produce quantifiable/ classifiable discrete cell states that monitor cell processes (e.g., mitosis).

The long range goal is to create an analytical system, preferably within a clinical pathology or observational basic cell biology modes of investigation, in which the measurements are interactively interrogated by the investigator and a computer program with mathematical models of cell biochemistry and integrated systems simulations running underneath.
