Senior🎓
Top SchoolPratik Sachdeva is a research scientist and postdoctoral scholar at UC Berkeley D-Lab with 10 years of experience applying data-driven methods to questions at the intersection of AI, society, and justice. He leads projects on AI evaluation and alignment, measuring hate speech with fine-tuned LLMs, and analyzing how training interventions like Constitutional AI shape model values. His background — a PhD in Physics and earlier work in theoretical neuroscience and ML — gives him a quantitative lens for complex computational social science problems. Pratik has advised over 60 interdisciplinary research projects and mentored more than 80 graduate fellows, building capacity for responsible AI across campuses. He also brings practical impact experience from a Data Science for Social Good fellowship where he developed tooling to detect vote dilution for litigation support. Known for bridging rigorous analysis with policy-relevant questions, he combines deep technical skill with a commitment to social justice.
