Tim Althoff

I develop computational methods to improve human well-being, combining techniques from data science, social network analysis, and natural language processing.

My research leverages detailed behavioral data from smartphones, smartwatches, and social interactions at the scale of billions of actions taken by millions of people, to realize new types of scientific approaches that generate actionable insights about our lives, health, and happiness.

I will be joining the Paul G. Allen School of Computer Science & Engineering at the University of Washington with an adjunct appointment in the UW iSchool as an assistant faculty member in January 2019. I will be looking for PhD students, so if you're interested please apply to UW and send me an e-mail. Go Huskies!
