"What does Engineering Biology mean to you?"
We invited members of the #EngBio community to share their definition of this evolving field. This is what Dr Indra Roux (@indraroux.bsky.social), Postdoctoral Researcher at the MRC Toxicology Unit (@mrc-tu.bsky.social), had to say.

#FacesOfEngBio
My definition of #EngineeringBiology has expanded: from synthetic biology in model chassis to designing diverse synthetic microbial communities. Many complex and resilient functions emerge at the microbiome level, so synthetic ecology is a promising approach for robust biotech. #FacesOfEngBio 🧬⚒️🧫
