Illustration of optical nanosensors for the detection of low concentration of chemical disinfectant.
Current Research Focus
Current Research Focus
My research focuses on creating new methods and materials to address potential threats to human and environmental health. We use near-infrared fluorescent single-walled carbon nanotubes (SWCNTs) as optical nanosensors for real-time detection of various target analytes. This includes studies on nanotubes coated in small molecules or polymers for the detection of emerging contaminants and biological indicators. Additionally, we investigated tuning nanotube optical properties via surface charge modulation and creating a protective barrier around the nanosensor to mitigate non-specific interactions.
More information about my research can be found in my presentations, publications, and research statement.

Other Research Experience
Other Research Experience
Other research experience included managing and analyzing student and industry client samples in the Analytical Services Lab at the Wilson College of Textiles. These samples ranged from polymeric to fiber substrates for material characterization via fourier transform infrared spectroscopy (FTIR), UV-vis and UV-vis NIR spectroscopy, thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), contact angle measurements, microscopy, and qualitative and quantitative fiber analysis. This also involved interactions with graduate students and faculty within TECS and other departments for communicating sample status and results.
