My journey in the US and in data science began as a PhD student at Northwestern University. My research focused on understanding complex network at work and understanding human behaviors and how they make decisions. This involved conducting both on-site and off-site research. Throughout this experience, I developed surveys, and used Python, statistics, machine learning, and network theories to analyze the results. I also applied models inspired by disease contagion and the adoption of innovations to quantify group behavior. Collaborating with a diverse team, I conducted experiments to observe peopl’s behaviors, incorporating user experience research methodologies to enhance app features and user interface.
