Additionally, his most notable achievement is his rise to an executive leadership role at Two Sigma, where he succeeded in a field traditionally dominated by formally trained quantitative researchers. Despite lacking a conventional academic background in mathematics or economics, he developed expertise through on-the-job training and mentorship from experienced professionals, ultimately becoming a quantitative researcher and leader.
