Research Description
The central theme of my research is the integration of functional genomics and computational methods to elucidate molecular mechanisms of disease and to identify potential therapeutic targets. We develop and apply computational methods and "omics" technologies to leverage the depth and dimensionality of data derived from a range of molecular levels, e.g. transcriptomics, small RNA sequencing, epigenetic events, and proteomics. We focus on characterization of cellular pathways and signaling events involved in disease progression and pathology. We are engaged in collaborative studies associated with a variety of cancers and tuberous sclerosis complex. In particular, we are investigating non-coding RNAs (e.g. microRNAs) and epigenetic events that are associated with alterations of the mTOR pathway. Our work with benign tumors that arise in tuberous sclerosis complex (TSC) patients may help determine why some mutations in the mTOR pathway lead to malignancies while others result in benign lesions. Our recent work has focused on the role of inter-cellular trafficking of RNAs by exosomes.
