I build bridges so no one has to be understood from a distance.

Entertainment Technology @ CMU · CS @ Brandeis '25 · Pittsburgh

Between languages, between minds that work differently, I look for gaps people treat as fixed and make them crossable, and fun to cross.

Being told about someone's experience produces agreement. Being placed inside it produces recognition.

Now at Carnegie Mellon's Entertainment Technology Center in Pittsburgh, the City of Bridges. Before that, CS at Brandeis and real-time 3D pose research at Peking University. I also build hardware, and keep one very stubborn 1983 Porsche 944 running.

02 / Experience & research

Peking University — HOME Lab

Jun 2025 – Dec 2025

Research Assistant, real-time 3D human pose estimation · Beijing

  • Implemented calibration and keypoint integration for sparse-sensor 3D motion reconstruction running in real time.
  • Built validation that traces intermediate results for joint stability, temporal consistency and latency, catching instabilities visual inspection missed.
  • Tied sensor placement and motion representation back to HCI uses: more natural virtual characters and real-time feedback.

Brandeis University

Jan 2024 – May 2024

Teaching Assistant, COSI 150A Compiler Design · Waltham, MA

  • Weekly office hours for 20+ students on lexing, parsing, code generation and optimization.
  • Graded exams and assignments; helped write lecture materials, problem sets and exam questions.

REON Technology

Jun 2023 – Jan 2024

Software Engineer Intern · Chelmsford, MA

  • Designed a data-validation layer (schema checks, timestamp alignment, unit normalization) so battery experiments produced trustable datasets on the first pass.
  • Dockerized the monitoring stack with structured logs and health probes: stable nightly runs, one-command deploys.
  • Built Jupyter dashboards turning raw cycles into SoC/SoH and event views used in weekly triage.

DIY Perks — authorized Bilibili channel

Nov 2020 – present

Channel Operator, Translator & Proofreader · Online

  • Lead a 7-person team localizing videos across Bilibili, Tencent, Baidu and Xigua on a weekly schedule.
  • 160+ videos, 250M cumulative views, 1M+ followers in the first month.
  • Negotiated 6 brand partnerships worth $25,000+; Python + Excel automation cut monthly accounting from 8 hours to 1.

03 / Leadership & awards

Brandeis PC Building Club

Nov 2023 – present

Founder & President · Waltham, MA

  • Started from zero; 25+ sign-ups in 48 hours.
  • Ran 6 workshops for 30 students, ending in 20 working PCs, plus parts-selection guides scored per use case.

Bit by Bit

Oct 2022 – May 2023

Director of Corporate Relations

  • Led 13 volunteers teaching free coding classes to public-school students during remote learning.
  • Designed a logic-gates module built in Minecraft Redstone for first-time coders.
