[Two-Stage Final Exams: An Assessment Strategy for Enhanced Collaborative Learning and Reduced Student Stress](https://www.tandfonline.com/doi/full/10.1080/0047231X.2026.2620442). *Journal of College Science Teaching* (2026). - add\_circle do\_not\_disturb\_on Abstract Two-stage exams, which pair a traditional individual exam with a subsequent collaborative, group exam, have been shown to enhance learning, retention, and student attitudes in midterm settings. This study investigates whether these benefits extend to... [Views on AI Existential Risk Before and After a Public Event at Harvard University](https://arxiv.org/abs/2603.27785). *arXiv* (2026). [Views on AI Existential Risk Before and After a Public Event at Harvard University](https://arxiv.org/abs/2603.27785). *arXiv* (2026). - add\_circle do\_not\_disturb\_on Abstract We report the results of identical pre- and post-event surveys given to attendees of a talk, two-sided conversation, and Q&A centered around the book If Anyone Builds It, Everyone Dies at Harvard University in March 2026, covering perceived probability of...

[Visualizing Mathieu-Type Dynamics in a Tabletop Magnetic Trap: A Coil-Driven Parametric Oscillator](https://arxiv.org/abs/2601.03409). *arXiv* (2026). - add\_circle do\_not\_disturb\_on Abstract We present a tabletop demonstration of dynamic stabilization and ponderomotive-like trapping using a pair of sinusoidally-driven anti-Helmholtz coils and a suspended permanent magnet. The oscillating field produces a rapid micromotion superimposed on a... ### 2025 [Active learning through flexible collaborative exams: Improving assessments across disciplines](https://journals.sagepub.com/doi/abs/10.1177/14697874251344293). *Active Learning in Higher Education* (2025). [Active learning through flexible collaborative exams: Improving assessments across disciplines](https://journals.sagepub.com/doi/abs/10.1177/14697874251344293). *Active Learning in Higher Education* (2025). - add\_circle do\_not\_disturb\_on Abstract Two-stage exams, which pair a traditional individual exam with a subsequent collaborative exam, are widely popular with both students and faculty for fostering deep engagement, collaboration, and immediate feedback. Over the last decade, this assessment...

[Demonstrating Dynamic Stability in Paul Traps: Exploring Rotating Saddles with Liquid Nitrogen Droplets](https://arxiv.org/pdf/2505.04035). *arXiv* (2025). - add\_circle do\_not\_disturb\_on Abstract Rotating saddle potentials provide a compelling visual demonstration of dynamic stability, widely used in undergraduate physics as mechanical analogs to the RF Paul trap. Traditional demonstrations typically rely on rolling ball bearings, whose frictional... [ More arrow\_circle\_right ](/publications)
