Curriculum Vitae

Research Interest

Academic interests include biochemistry and biotechnology, cell and molecular, and membrane biology. Research interests are directed towards understanding receptor mediated signal transduction as well as intracellular signaling mechanisms in relation to environmental changes or in disease states. These projects involve studies on the role of G-proteins and their receptors, second messengers such as inositol polyphosphates, cyclic nucleotides (cAMP, cGMP), protein kinases and phosphatases in regulation of cellular processes. Among inositol polyphosphate second messengers, we are particularly interested in higher inositol polyphosphates i.e. inositol polyphosphate pyrophosphates (IP7 and IP8) in relation to their metabolism, cellular levels under adverse conditions and their role in cellular processes. Emphasis is placed on subcellular compartmentalization, vesicular membrane trafficking, protein-protein interactions, and cellular regulation of apoptosis, endo- and exocytosis, and maintenance of cell polarity in epithelial cells. My laboratory is also interested in bioinformatics studying global profiling of gene expression using microarray and proteomics approaches under altered environmental conditions. We are particularly interested in identification of functional motives and their phylogenetic adaptations by higher life forms. Biomedical engineering interests include development and characterization of biocompatible materials for medical implants and computational modeling of carcinogenesis.
