Research in our group involves the development of novel sensing tools and strategies for the monitoring of biological and environmental systems at both the nano- and macro-scales. On the nano-scale, we are developing implantable sensors capable of being inserted into individual cells and optically positioned for the monitoring of cellular response to various external stimuli. On the macro-scale, we are developing new spectroscopic techniques for real-time disease (i.e., cancer) diagnosis in clinical and surgical settings.
