Bioengineer Jessica Griffiths (Get to Know a Scientist!)

A Bioengineering PhD student discusses their research on the gut-brain axis, focusing on the gut microbiome's role in digestion, immune, and nervous system functions. They explore the link between autism and gastrointestinal issues, using various lab techniques to study these connections. The student shares their experiences as a PhD candidate, balancing lab work with personal interests, and their journey into science communication.

What is the primary focus of bioengineering as described in the video?

• Application of engineering principles to biological systems
