Hey, I’m Leonardo!
I'm a CS Ph.D. student at USC, advised by Prof. Emilio Ferrara. I like the idea of applying engineering to social systems and I'm interested in studying social agents and artificial societies.

Korean food culture
In the fall, I studied abroad at Yonsei University while taking an online Food Culture class at SJSU. My research topic for the semester was the Korean food culture. I watched Korean movies, read papers on Korean history, went to Korean restaurants, and talked to Koreans. All while in Korea! I was completely submerged in my study abroad experience, and I loved every bit of it.
