My laboratory has three major areas of interest: 1) high-resolution microscopic imaging to study cancer treatment in vivo; 2) Using bioorthogonal chemistries to analyze intracellular protein networks involved in the molecular pathogenesis of complex human diseases to identify novel imaging and therapeutic targets; 3) Development of novel miniaturized sensing technologies (chips) for real-time high-throughput analysis of problems in biology.
