Lindsey Ma 马兰馨

I am a software engineer intern at Arborphy AI, an early-stage startup, where I build and deploy machine learning systems for computer vision. I am broadly interested in machine learning and computational neuroscience.

I received my M.S. in Statistics from Columbia University and my B.A. in Economics from Renmin University of China.

Experience

I build and deploy machine learning systems for computer vision.

Real-time player pose and shuttlecock detection for a badminton training system

Real-Time Vision for Robotics

Software Engineer, InnoX Academy Robotics Lab
May 2025 – December 2025, Shenzhen

I fine-tuned YOLO for player and shuttlecock detection and pose estimation in a real-time badminton training system.

I built the real-time vision pipeline to track shuttlecock trajectories and estimate speed, optimizing inference to 30 FPS on a Raspberry Pi.

I integrated a local LLM-based voice interface for hands-free robot control using Ollama, a microphone, and a speaker.

Research

In Liam Paninski’s lab, I worked on recovering neural signals from noisy two-photon calcium imaging.

Selected Projects

Three-dimensional UMAP embedding of the FlyWire connectome

Community Structure in the FlyWire Connectome

Computational Statistics Project, May 2025

Applied Bayesian stochastic block models to the FlyWire whole-brain connectome to infer cell-type organization; evaluated community structure with posterior predictive checks and visualized embeddings with UMAP.

Bayesian modeling · Connectomics

Common spatial pattern maps used for EEG motor-imagery decoding

Motor-Imagery Decoding from EEG

Brain Computer Interfaces Lab Project, January 2025

Extracted spatial features from real-time EEG recordings using Common Spatial Pattern (CSP) and trained a linear discriminant analysis (LDA) classifier to decode left- versus right-hand motor imagery, achieving 80% mean accuracy.
