DongYu Weng

Sophomore at Carleton College • Physics & Computer Science

I build at the intersection of low-level systems and physical hardware. As a manager at the Carleton Makerspace, I focus on making complex physical phenomena tangible through digital fabrication and custom-built software tools.

Optics Outreach Systems Programming Digital Fabrication

My Working Style

My work is driven by the belief that truly understanding a system requires building it from the ground up. Whether it's a Scheme interpreter in C or a high-torque granulator for PLA reclamation, I design tools that are robust, transparent, and educational.

Currently, I am a researcher in the Optics Education Lab where I prototype hardware to help visualize optical principles for outreach and classroom settings.

Research Experience

Optics Education Research

Jan 2026 – Present

Research Assistant | Carleton College

Collaborating with Martha-Elizabeth Baylor to develop foundational optics outreach materials. Focusing on hands-on hardware to bridge the gap between abstract physics and early childhood education.

Selected Projects

Scheme Interpreter

A recursive bottom-up parser and environment-model evaluator built in C. Built from scratch to understand the fundamentals of language implementation.

C Systems

Chaotic Oscillator Analysis

Simulating Asymmetric Coupled Duffing Oscillators. Used NumPy for high-speed vectorization to generate Poincaré sections and analyze Permutation Entropy.

Python NumPy
