§ 1 The engineer, in brief

Undergraduate · Mechanical Engineering

I build things that have to survive the real world — rockets, batteries, instruments. Before rockets: a 4WD car and an Arduino trash can that opened itself. The question that keeps me at this desk: how do structures behave at their limits?

§ 2 Battery Mechanics

Research · Prof. Juner Zhu

Two Abaqus/Explicit studies of spiral-wound cells, built end-to-end. A plane-strain model resolves all eight layers before any buckling — checked against published values to ~0.1% on one case. A plane-stress model heats a single wound strip inside a rigid casing — the monitor shows its real stress field.

Environmental Box

CAPSTONE · 2026 · Team member

An environment for evaporation experiments, integrating six subsystems. My work: simpler controls and thermal / moisture choices.

Open the capstone →

Sorbicore

Design study · Designer · independent

A 1 m amateur high-power rocket modelled part-by-part as parametric CAD-as-code (ForgeCAD) — 104 runtime checks, conservative predicted apogee 200–250 m. Design-complete, digitally validated — not built or flown.

Multi-Engine Rocketry

2019–2023 · ten airframes · Designer & Builder

Ten airframes, 2019–2023, from a 10 m water rocket to a multi-engine vehicle past 100 m — a program that produced two Chinese patents: the multi-engine rocket design, and a wireless launch device (utility model).

Battery Mechanics FEA

Spring 2026 – · Undergraduate Researcher · Prof. Juner Zhu

Two 2D Abaqus/Explicit studies of spiral-wound lithium-ion cells, built end-to-end: an eight-layer plane-strain model checked against published values to ~0.1% on one case, and a plane-stress winding study of a heated strip in a rigid casing, run as scripted, automated batches.

Agentic Abaqus Workflow

2026 · Independent

Custom skills let a coding agent drive the full Abaqus loop — rebuild, mesh, extract — escalating hard cases to a supervisor model and running 24h+ unattended; built to accelerate the jelly-roll modeling. A public write-up of the workflow (X, Apr 2026) circulated widely (~261K views).

Indoor Air Quality Study

ME 4505 term project · Team lead of 4 · Prof. Smyser

Late-fall field study of five campus spaces with a self-assembled CO₂ / PM2.5 sensor box — twenty 10-minute sessions; location-mean CO₂ and PM2.5 correlate at r ≈ 0.96 (n = 5, p < 0.01).

BLE Dog Health Monitor

GE1501 · Fall 2023 · Team lead of 4

Wearable harness with two Arduino Nano 33 BLE boards monitoring canine heart rate, temperature and activity over Bluetooth — sensors, firmware and 3D-printed enclosure designed from scratch. A first-year design-course prototype, demonstrated on a dog model at the Expo.

FRC Robot Software

2021–2023 · Software team member

Java control code and debugging tools for a competition robot, two FIRST Robotics seasons; sensors and actuators integrated with the mechanical and electrical subteams, debugged under match-time pressure.

GlassGPT

Ongoing · iOS Developer

A native iOS/iPadOS chat client (SwiftUI · SwiftData) with an actor-isolated runtime, structured as 16 SwiftPM modules behind hard CI gates — an LLM client built like an instrument. Built fully on the iOS 26 Liquid Glass design language before it was in wide use, with LaTeX / formula rendering.

Scope — two separate simulation studies: an eight-layer plane-strain model and a homogeneous plane-stress winding model (the parameters listed are the winding model’s). Neither simulates buckling.

  • Abaqus/Explicit — 2D plane-strain and plane-stress finite-element solver (Dassault Systèmes).
