About Me

Who I Am

I’m a Nanofabrication Process Engineer and fourth-year Ph.D. candidate in Electrical Engineering, with over 4 years of hands-on experience in CMOS-compatible fabrication, FIB-SEM, EDS, AFM, UV-Vis, FTIR, and Raman spectroscopy.

My work spans across three advanced ZEISS SEM platforms at MIT.nano and SUNY Buffalo, where I’ve driven a sensor fabrication process and achieved high accuracy in nanoscale feature extraction from SEM Imaging. I specialize in bridging design, fabrication, and marketing teams through feedback-driven workflows that accelerate iteration and insight.

My research contributions include multiple publications and a patent-pending sensor platform. I bring a strong background in biosensing, yield analysis, and defect diagnostics, with a focus on scalable nanomanufacturing solutions.

Beyond the lab, I serve as Vice President of the Electrical Engineering Graduate Student Association at SUNY Buffalo, where I advocate for research excellence and student leadership.
