What we are building right now, with collaborators and students.

Research Project

AI in K-12 Math Education

Part of the Gates Foundation-funded MentirAI project, this research builds an AI-powered math tutoring assistant on the historic Mathforum problem-thread archive, exploring RAG (retrieval-augmented generation) and fine-tuning strategies to provide pedagogically sound feedback on student mathematical thinking, in collaboration with Jason Silverman. The work extends into broader investigations of AI applications in educational contexts — including generative AI, classroom integration, and pedagogy — conducted with students across CS394 and the Honors thesis sequence (CS491–CS492). This collaboration began in 2019.

End-to-End Intelligent Cardiorespiratory Monitor

A full-stack wearable system in collaboration with the Drexel Wireless Systems Lab for continuous, ambulatory cardiorespiratory monitoring. The project integrates signal acquisition, edge processing, and machine learning inference for real-time health monitoring outside clinical settings, and includes the IoT Sensor Framework (a HIPAA-compliant platform for collecting data from IoT-based sensors including knitted smart textiles) and the IoT Processing Framework (real-time and offline signal processing and machine learning on sensor data), both developed with the Drexel Wireless Systems Lab. Related student work includes multi-semester research in RF-based biomedical signal acquisition and analysis using wearable IoT devices (conducted across CS391 and CS394), independent study in multi-sensor data fusion techniques for wearable and IoT applications (conducted in CS392), and a machine learning pipeline for minute-level and subject-level sleep apnea detection using ECG signals (presented at Ursinus CoSA 2026 by Andrei Bogdan). We became involved in this research in 2013.

RF Antenna State Selection for Localization and Tracking

Research into intelligent antenna state selection for RFID-based sensing in collaboration with the Drexel Wireless Systems Lab, targeting improved read range and accuracy in multi-tag environments. Related student research includes RFID-based indoor localization, multi-tag tracking, and dynamic radar sensing techniques, as well as research and educational module development for software-defined radio (SDR) platforms in smart-grid communication scenarios, conducted across CS392 and CS394. We became involved in this research in 2016.

NVIZ: Neural Network Visualizer

An interactive, no-code neural network visualizer that lets users upload data, define a network architecture, train a model, and explore its behavior through Sankey diagram visualizations — all in the browser. Developed by Ursinus students Kevin Hoffman and Michael Cummins. Source on GitHub. Related work includes tools for making machine learning model decisions more interpretable and transparent (presented at Ursinus CoSA 2025 by Michael Cummins), and independent studies developing methods to visualize internal feature representations in trained neural networks. Conducted by multiple students across CS391 and CS392. Development began in 2022.

Pixel Pandemonium

An "unplugged" interactive activity for teaching computer science fundamentals through pixel-based visual demonstrations — no computer required. Participants fill in grids to recreate images and animations, building intuition for how digital graphics, encoding, and algorithms work. The activity has been presented at venues including CSTA, CS4Philly, CS4AllPA, the Philadelphia Science Festival, and Pixar, and can be explored at the Pixel Pandemonium drawing canvas. Developed in part through independent research projects by two students in CS394. This work began in 2022.
