  • Engineered a novel and compact plasmonics-based optical filter offering customizable tunability across broad infrared wavelength bands with significantly improved performance and reduced footprint. To achieve optimal filter geometries, spearheaded multi-parameter optimization by integrating genetic-algorithm search frameworks with GPU-accelerated FDTD simulations that met stringent design specifications. Complemented this development by designing an easy-to-use FTIR plus integrating-sphere platform for comprehensive IR filter characterization, delivering rapid and high-fidelity datasets across mid- and long-wave IR scattering, reflection, and transmission properties. Advanced real-world device modeling through a Python-based pipeline that seamlessly integrates high-resolution spectroscopic data into existing workflows, significantly boosting prediction accuracy under atmospheric conditions.

  • Advisor : Prof. Ronald K. Hanson
  • During my PhD at Stanford, I have led several projects focused on designing and deploying advanced optical and opto-mechanical systems for extreme environments. My hands-on research spans gas, DFB, UV, pulsed, and quantum cascade lasers, precise laser alignment, and robust opto-mechanical integration. I developed diagnostics for studying high-temperature and high-pressure systems using absorption, emission, and dual-comb spectroscopy in ultra-high vacuum and complex combustion setups. My technical toolkit includes advanced optical design with Zemax and Lumerical, mechanical modeling and CAD in SolidWorks, and simulation-driven analysis with ANSYS tools. I built custom Python and MATLAB pipelines for data acquisition, spectral analysis, and automation of measurements, which underpinned my ability to rapidly process complex datasets and optimize system performance. These strengths are complemented by experience in cleanroom fabrication, infrared sensor integration, and advanced analytical methods for challenging, real-world applications.
