And nobody really knows what epidemiology is.

There's almost no epidemiology or studies on it.

You know, from physics to medicine, in particular, epidemiology and also mathematical modeling.

And I think that's the funniest epidemiology joke that you will ever hear.

Exactly a year ago a formal study led by Dr. Jacqueline Clavel a formal study led by Dr. Jacqueline Clavel head of the enrironmental epidemiology of cancers department at INSERM head of the enrironmental epidemiology of cancers department at INSERM head of the enrironmental epidemiology of cancers department at INSERM pinpointed an excess of childhood leukemia cases around 19 French nuclear sites. around 19 French nuclear sites.

Epidemiology is the science of how we know in the real world if something is good for you or bad for you.

And she was unusual because she was really interested in a new science, the emerging field of epidemiology, the study of patterns in disease.

But I'm going to use tools and ideas that are familiar to economists to think about a problem that's more traditionally part of public health and epidemiology.

It's similar to this idea of epidemiology like between people networks and how does it spread and whether you are more susceptible to get a virus than not.

Seva got started because we wanted to apply these lessons of surveillance and epidemiology to something which nobody else was looking at as a public health issue blindness, which heretofore had been thought of only as a clinical disease.
