Tim Althoff

My research develops computational methods that leverage large-scale behavioral data to extract actionable insights about our lives, health and happiness through combining techniques from data science, social network analysis, and natural language processing. I consider this Behavioral Data Science.

I lead the Behavioral Data Science Group which works on research related to mental health, misinformation online, scientific reproducibility, and informing the COVID-19 response.

We have a postdoc position available.

I am also looking for PhD students, especially in but not limited to deep learning, causal inference, data science and mobile health. If you're interested please apply to the UW Allen School. Go Dawgs!
