Belén Saldías

PhD Candidate

I’m a third-year Ph.D. student; I joined LSM/CCC in 2018 and have been a research assistant here since then. I’ve worked in various research projects in multiple domains such as variational inference applications, human-computer interaction, online RCTs, and natural language processing. Within CCC, some of these projects include 1) INSPIRE, aimed at exposing middle-schoolers to role models to help enhance metacognitive traits, and 2) matching personal narratives. With external collaboration, I also developed 3) Tweet Moodifier, a tool aimed at increasing emotional awareness in social media. I’m currently working in child-aware machine learning, specifically thinking about content “annotation/moderation” and transparency. In my “spare” time, I serve in the executive council at MIT Sidney Pacific Grad Community. Besides that, I enjoy biking and walking around the Boston area, enjoying meals with friends, playing SBS soccer leagues, and learning about sports. Further, I’m a big supporter and fan of Shakira.
