I'm a first-year Master's student in Data Science at Sabancı University, advised by Dr. Onur Varol. My research interests lie at the intersection of computational social science, network analysis, and algorithmic fairness.

Currently, I'm investigating algorithmic fairness and systemic bias on Bluesky, specifically focusing on how curation mechanisms shape network structure and user exposure.

— Music

I'll listen to almost anything, but lately it's mostly K-pop, rap, Japanese folk, progressive rock, and K-indie. I also play guitar. Though I must say, I like my HSS Strat and how I look with it.

— Movies

I love whodunnits and murder mysteries and could genuinely talk about them for hours. Also into psychological thrillers and Korean cinema. Park Chan-wook especially.

— Other Media

Some YouTube channels I watch regularly and think are worth your time: Veritasium, The Rest Is Science, Howtown, neo, fern, WVFRM Podcast, and Mic The Snare.

— Other Interests

Linguistics, etymology, mathematics, sociology, urban studies. I game sometimes too.
