Bringing Cohorts in Cahoots with Lab Science

Adverse Reactions

The fields of epidemiology and toxicology sometimes find themselves at odds, but Gradient’s Julie Goodman, an epidemiologist and toxicologist, shares how the two disciplines can complement each other to evaluate public health risks. Dr. Goodman also dives into the finer points of systemic reviews and meta-analyses in her conversation with co-hosts Anne Chappelle and David Faulkner.
