About

I’m a Graduate Student Researcher at the Cottrell Lab at UC San Diego, where I study perceptual expertise and human face recognition using deep learning and cognitive science. Having recently completed my first year as a Master’s student, I bring a solid foundation in programming, data structures, and machine learning, and am actively seeking opportunities in Artificial Intelligence and Machine Learning.
