I had the pleasure to work with a top geneticist whose domain of specialty was the microbiome, and he continually insisted there are tons of discoveries to be made in the arena (which he and those researchers we sequenced for did often, from dentistry to studies of the monitor lizard to chrons disease, just all over in subjects you might not expect).

Less on topic, I learned how to read scientific papers and filter bullshit ones (even in respectable journals) from good ones under his tutelage, and am forever grateful to the vast array of science and tech I was exposed to while supporting the tech side of a "every major sequencer" sequencing lab.
