Research Interests

Our research laboratory develops novel imaging and fluidic technologies for biomarker discovery and translation. We develop stimulated Raman scattering microscopy for label-free visualization of steatosis in pathologic tissues for early-stage disease detection. In addition, we develop nanofluidic technologies to detect protein post-translational modifications (PTMs) in tissue and liquid biopsies. We use protein PTM profiles as surrogates for signal transduction activities to classify disease subtypes. We exploit signal transduction pathways as therapeutic targets for nutrition intervention using synergistic combinations of phytonutrients, or natural compounds found in plants. Furthermore, we develop electroporative micro- and milli-fluidic technologies for circulating tumor cell diagnostics and therapeutics. Collectively, our technologies are suitable for the studies of obesity, type 2 diabetes, fatty liver disease, cancer metastasis, and neurodegenerative diseases.
