Amazing. 10/10.

I’m a high schooler who hasn’t really had the chance to make any microbiology classes, but this makes me want to go into the field. Comprehensive enough that you don’t have to be a microbiologist or have some fancy degree to understand what they’re talking about, but they don’t dumb it down which is nice. Great podcast!

Journal club reimagined

I always think that if this had been what journal club was like, it would have been a lot more fun. Just talking through good papers and good science (without picking apart every figure) and having some laughs. Good times!

Great podcast very informative!

This is a 10/10 as well as all the podcasts made by the same host, highly recommend.
