Testimonial
In his words
From physics into applied AI, and a winter in Boston, Cambridge, where he met researchers who had made the same switch from non-CS backgrounds.
“Since we are transitioning from a non-CS background to something more computational, their insight for us was really crucial.”
“The project lead mentioned that the way we framed the problem was very holistic, and that we managed to cover most bases that we were never actually taught in class.”
“It turned out that most of them were also from non-CS backgrounds and also transitioned into the field.”
On-Campus Experience · February 2026
Winter in Boston, Cambridge
Two projects on campus, and a talk at the AI+X Meetup in Kendall Square in front of nearly 200 people.
