research on visual perception and computational neuroscience, alongside technical projects.
current research
Using representational similarity analysis to compare classical vision models (HMAX, Gabor pyramids) against state of the art deep networks, benchmarked against human fMRI data from early visual cortex. The goal is to understand what structural properties of a model drive brain alignment, and whether simplicity can beat scale.
- found that HMAX exhibits stronger alignment with V1 than recent hyper-complex architectures
- accepted as extended abstract at UniReps, NeurIPS 2025 and contributed talk at VSS 2026
A synthetic image generation pipeline and model introspection framework studying how CNNs handle visual search in structured environments. This URCA grant funded project asks whether neural networks solve visual search the same way humans do, or whether they cheat by relying on statistical regularities in backgrounds rather than the target itself.
- trained multiple CNN architectures to >90% accuracy; found models rely on background context rather than target features
- presented as poster and oral talk at UCSB URCA Week 2025
Studying how humans and large language models evaluate fake expertise in image captions — whether AI systems can detect and be deceived by misleading descriptions. We curated 360 images with intentionally misleading descriptions across five knowledge domains, collected human deceptiveness ratings, and compared them to GPT-4 and Gemini-2.5 judgments.
- follow-up study underway on decision making and trust formation under deceptive information
selected projects
An AI-powered academic workspace integrating Canvas, Gradescope, and Piazza into a single interface.
