About

I’m an economics PhD working in causal inference problems. I have experience in academia and the tech industry. My expertise is in causal inference with observational and experimental data leveraging tools such as causal ML, propensity score matching, double machine learning, and causal forests, A/B testing, quasi-experiments, RCT's. I am skilled in Python, SQL, pySpark, and I enjoy working closely with stakeholders, data scientists, and engineering teams to bring ideas into production and automate and scale products. I love the challenge of discussing and solving ambiguous problems, continuously learning new skills and mentoring colleagues.
