Yama Chang's profile picture

Hi, I'm Yama.

As a Data Scientist, I bring a unique blend of machine learning, analytics, behavioral science, and experimental design expertise. I focus on enhancing efficiency, driving decision-making through data and actionable insights, and developing practical solutions for real-world challenges. Known for being a quick learner and adept problem solver, I leverage my robust analytical capabilities and strong communication skills in every project.

I have honed my expertise at the intersection of data science and digital mental health. Harnessing computational techniques, I aim to leverage large-scale behavioral and language data to extract actionable insights to improve mental health. My goal is to develop accessible, scalable, evidence-based interventions to ameliorate disparities in mental health care. I am also interested in exploring the potential of large language models and artificial intelligence in delivering timely and personalized mental health support.

Currently, I'm building a machine learning pipeline to analyze time-series data on depression symptom changes at the Lab for Scalable Mental Health, contributing to groundbreaking work in the field.
