About
Hi! I’m Irena, a second-year CS Ph.D. at Stanford University, advised by Carlos Guestrin. My research interests center on trustworthy machine learning, especially in the context of large models.
Previously, I also did my undergraduate at Stanford, where I studied Computer Science (B.S. with honors), Statistics (M.S.), and a bit of art history. Here’s a randomly sampled favorite artwork.
Very kind researchers have had an outsized impact on my career. If I can be helpful in your journey (e.g. by suggesting classes or chatting about grad school), feel free to email me at my first name [at] cs.stanford.edu.
