Rex Fernando

I am a research scientist at Aptos Labs.

Previously, I was a postdoctoral fellow in the Carnegie Mellon School of Computer Science, hosted by Aayush Jain and Elaine Shi. I graduated in 2022 with a PhD from UCLA, where I was advised by Amit Sahai. Before coming to UCLA, I received a M.S. at UW - Madison. While there I did research with Eric Bach.

During my PhD, I spent the summer of 2019 working with Alon Rosen at the FACT Center in IDC Herzliya. From January to September 2020, I was an intern at NTT Research in the Bay Area, working with Ilan Komargodski. I also visited Elaine Shi at Carnegie Mellon University during 2021. Finally, during the summer of 2022 I worked as an intern on Meta's blockchain research group.
