Portrait of Filbert Aurelian Tjiaranata

Filbert Aurelian Tjiaranata

Final-year CS Undergraduate at Universitas Indonesia
Research Assistant at CHAI Lab

Halo! I am a rising final-year Computer Science undergraduate at Universitas Indonesia. I have been very fortunate to work with Prof. Chenhao Tan at the Chicago Human+AI (CHAI) Lab. My main interest is in agentic AI, especially building agents that accelerate scientific research — though I am excited to apply them to other domains too. Earlier, I worked on multilinguality and multiculturality in NLP and also explored a bit of AI safety.

Outside of research, I enjoy badminton, basketball, swimming, bouldering, hiking and once-a-year of surfing! There was a time when I enjoyed competitive programming, but not anymore :D
