I am a postdoctoral researcher and statistical consultant in the Department of Social Neuroscience at the Max Planck Institute for Human Cognitive and Brain Sciences. I conducted my graduate work at the University of North Carolina at Chapel Hill as part of the Positive Emotions and Psychophysiology Lab.

My research explores the intertwined relationships that link physiological processes and social behavior, as described by the socio-autonomic spiral model of social connection.

My statistical work is conducted primarily in R with a focus on visualizing and analysing hierarchical and complex datasets.
