Studying the biology of the circadian clock: Dr Aarti Jagannath

TL;DR

Oxford researcher delves into the significance of circadian rhythms and sleep in regulating behavior and overall health.

Transcript

I grew up in India and I came to Oxford to do a defill after which I started research on circadian rhythms where my research interest was trying to understand how this 24-hour clock knows what the time is so how does it pick up light cues from the world and how does it use this information to then set itself to the right time now I have my own lab ...
