Justin has been covering science news as a host of This Week in Science (TWIS podcast) since 2004. The weekly program brings a slightly irreverent, yet fervently pro-science perspective to recent research across all scientific subjects. While he has previously worked in biotech research labs running fermentation experiments and in genomics labs running next-generation sequencers, Justin’s first love of science is in communicating the stories to a wider audience.
