William Berrios

I’m William, a bachelor in Mechatronics Engineering (Robotics 🤖) from UNI. Currently, I am working as a research intern at the The Center for Brains, Minds & Machines - MIT working with Arturo Deza examining the potential of Visual Transformers and adversarial training on the modeling of the ventral stream processing. Previously, I worked as a computer vision research intern developing a deep active learning framework to help curators efficiently label biomedical images at the Electronic Visualization Laboratory under the supervision of Professor Elisabeta Marai.

My research interests lie in building robust and generalizable computer vision systems with minimal or no supervision. Specific areas of interest are representation learning, generative modeling, few-shot learning, adversarial robustness and robotics.

Eager to contribute to science development in Peru, I am actively organizing meetings with graduate students in computer science at REPU for peruvian undergraduates. This year, I am looking forward to pursuing a PhD in Computer Science and becoming a first-generation graduate student in my family.
