Professional Experience

Undergraduate Research Assistant
University of Texas at Dallas

Oct 2019 - Present
Richardson, TX

  • Harnessed the properties of magnetic materials to explore and implement beyond-CMOS technologies for Dr. Joseph Friedman’s NeuroSpinCompute laboratory
  • Designed micromagnetic skyrmion logic structures and performed Mumax3 simulations using voltage-controlled magnetic anisotropy (VCMA) for skyrmion synchronization and propagation

Hardware Engineering Intern
Microsoft

May 2022 - July 2022
Raleigh, NC

  • Helped develop a custom floorplanning step by pre-placing standard cells and buffers and pre-routing trunks on high-speed critical buses to achieve flop to flop reach in several millimeters
  • Created an interpreter between Innovus and Fusion Compiler (FC) for our TCL Physical Design scripts, aiding my team’s translation effort
  • Improved the efficiency of my translated floorplanning procedures for a SOC block by over fifty percent

Undergraduate Researcher
Universidad de Salamanca

Jan 2022 - May 2022
Salamanca, Spain

  • Designed ultra-low dissipation reversible skyrmion logic circuits to reduce energy consumption by over two orders of magnitude
  • Developing mathematical models to simulate complex micromagnetic devices more efficiently

Research Experience for Undergraduates
University of Texas at Austin

May 2021 - Aug 2021
Austin, TX

  • Fabricated, and tested WSe2-based devices for Dr. Jean Anne Incorvia’s Integrated Nano Computing lab
  • Performed tape exfoliation, electron beam lithography (EBL), atomic force microscopy (AFM), and magneto-optic Kerr effect (MOKE) imaging to fabricate and validate device structure and operation
  • Created field-effect transistors (FETs) with ambipolar behavior, demonstrating the valley-Hall effect

Electrical Engineering Intern
Texas Analog Center for Excellence

Jan 2021 - Aug 2021
Richardson, TX

  • Helped design a spin transfer torque (STT) memristor-based neuromorphic chip, collaborating with graduate students
  • Verified aspects of device’s logical operation via Verilog to prepare tapeout for foundry

Barry Goldwater Scholarship
March 2022
Undergraduate Research Scholar Award
Feb 2022 & Feb 2021
Competing with other UTD undergraduates in a research competition, work won the Undergraduate Research Scholar Award twice.
TxACE Best Poster Award
Oct 2021
I presented my independent research at the Texas Analog Center for Excellence Symposium and won the Best Poster Award and $150, competing against over 40 graduate students.
CometHack First Place
Apr 2021
With a team of three, I built and programmed a custom thermostat that uses gradient descent to calculate the thermal resistance of its surroundings, for the reduction of energy consumption.
National Merit Scholar
Mar 2019
I ranked in the top 0.5% of all US students to join UTD’s competitive National Merit Scholarship Program (NMSP) to receive scholarships worth over $200k. Via the NMSP, I am an active participant in an elite interdisciplinary scholarship community.
