I’m a fifth-year Ph.D. student in Computer Science at EPFL, advised by Robert West in the Data Science Lab. Drawing methods from causal inference, NLP, and data science, in my research, I aim to provide actionable insights about our behaviors, language, well-being, diets, and health. To this end, I develop observational and experimental study designs relying on large-scale digital data sources, such as purchase logs, Web, social media, and crowdsourcing. I also study biases of such digital traces.
