This week you have learned about how the food you eat influences your metabolism and digestive processes. When considering these digestive processes, we tend to think about the organs of the gut, including the colon; however, it turns out there are other cells that are just as important to our digestive health – bacterial cells. This leads us to our next scientist in the “Get to Know a Scientist” series.

Dr. Lawrence David is a biologist currently working as a professor at Duke University. His work examines the intersections of diet, the digestive system, and gut bacteria. More specifically, his lab focuses on how the microbes in our guts behave over time and in response to dietary changes. In addition to work in his lab, he also helped start a website (Links to an external site.) to showcase illustrated, science-related poetry. 

  1. If you haven’t already, watch the following short video that highlights the inspiration behind Dr. David’s research.

  1. Nest, listen to Dr. Lawrence David’s story of an extreme self-study (Links to an external site.) (14:15). Alternatively, you can read the transcript (Links to an external site.) of this story.
  2. Lastly, read this interview from The Chronicle (Links to an external site.) that highlights Dr. David’s educational background and examines his research a bit further.
