Profile

I am a psychologist and applied statistician with an extensive background in data science.

My research focuses on understanding and describing the changes in performance across the lifetime. I am interested in skill development and expertise, as well as, preserving effects of expertise on the age-related declines in performance. My work often explores novel usage of statistical methods on the existing or passively collected large data in psychology and medical sciences.
