A little harsh, perhaps, but Raghu Parthasarathy can probably relate. Parthasarathy is a physicist at the University of Oregon whose work crosses over into biology, chemistry and neuroscience.
His work includes researching the microbiome of the gut, which influences a person's overall health.
He is our guest in this month's edition of cUriOus: Where Research Meets Radio. You can read more about his research on his blog, The Eighteenth Elephant.
