My research expertise lies at the interface of plasmonic nanomaterials, spectroscopy, microscopy, and multivariate data analysis, with a focus on solving analytical and environmental chemistry problems through quantitative approaches. I use Raman and surface-enhanced Raman spectroscopy (SERS), fluorescence spectroscopy, mass spectrometry, nanoplasmonic platforms, and chemometric modeling to develop advanced sensing and imaging methods for chemical, biological, environmental, and forensic analytes.
My current and future research focuses on the development of plasmonic nanosensors, 3-D imaging methods, and data-driven chemometric models for the molecular detection and quantitative profiling of biomarkers, conventional and emerging environmental contaminants, and the 'forever chemicals'. A central component of my research program is the integration of undergraduate and graduate students into interdisciplinary projects that combine nanomaterials, analytical instrumentation, and computational data analysis.
