Xiao Li, postdoctoral fellow at the Snyder Lab in the Department of Genetics at Stanford University, at the Quantified Self Symposium 2018.

Xiao Li is a lead author on the recent paper “Digital Health: Tracking Physiomes and Activity Using Wearable Biosensors Reveals Useful Health-Related Information.” In this talk, she describes how starting with data from a single individual person can expose previously unnoticed phenomena, showing evidence that outlier heart rate and skin temperatures can predict sickness onset, sometimes over 10 days in advance, and that heart rate differences can distinguish between insulin sensitive and insulin resistant states.
