BS/MS @ Northwestern University: major in electrical engineering and minor in material science and engineering.

Signal Integrity Engineer at Intel. I am interested in developing knowledge of electronics across all layers from understanding semiconductor device fabrication to low level device programming to high level human centered design.

Work Experience

Signal Integrity Engineer

Intel

  • Measured high‑speed channels (PCIe, Ethernet, DRR) using TDR and VNA to root-cause signal integrity issues; including on-package RF probing up to 67 GHz
  • Developed python automation for lab measurement instruments such as oscilloscopes, VNAs, and BERTs as well as post-processing of collected data using MATLAB and Python
  • Created methodology for optimizing transceiver equalization in the lab leading to significant time savings compared to previous brute force approaches and published findings in an internal journal
  • Migrated a MATLAB PCB transmission line modeling application into a cloud hosted Python web application
  • Adapted machine learning workflows for signal integrity needs to generate behavioral TX driver models from silicon netlists using MATLAB
