Profile
My scientific specialty is chronobiology (circadian rhythms and photoperiodism), with additional interests in comparative physiology, animal behavior and evolution. I am not an MD so I cannot diagnose and treat your sleep problems. As well as writing this blog, I am also the Online Discussion Expert for PLoS. This is a personal blog and opinions within it in no way reflect the policies of PLoS. You can contact me at: Coturnix@gmail.com
