My research program is to develop a new generation of brain science (and training scientists) focused on explaining complex real-world behavioral patterns. We actively partner with clinics to leverage our new-found fundamental understanding of the human brain and behavior for developing modern digital health systems.
To discover the neural and behavioral processes underlying real-world behavior we focus on day-to-day smartphone interactions in conjunction with a range of data: from neural data stemming from brain implants to laboratory tasks. Our pursuit to unravel real-world behavior leverages the rapidly growing fields of data science and complexity science.
Our focus on the real world has a growing imprint – from capturing how we age to discovering fundamental patterns like multi-day behavioral rhythms. We also play a foundational role in launching spin-offs that focus on solving real-world problems using the science and technology developed in our laboratory.
