Mentoring is sharing. Sharing knowledge, resources, network, and space for our mentees to take control of their careers and shine their unique lights.

I hope the #structure in this paper will spur further #research into understanding not only how bacteria "see" changes, but how we can use this knowledge to come up with approaches that cripple #pathogens and provide new avenues for #antimicrobial development 💊

I'm so grateful for all the deeply satisfying interactions, relationships and discovery that have happened across MANY #gradstudent and #postdoc journeys!! 🙏

Happy to share this protocol that myself and my Ph.D student @SarahP4464 work on! This in vitro polymicrobial model is at the core of my postdoctoral work during my time in @GeiselBiofilm lab. biorxiv.org/content/10.1101/… See link 👇🏾 for details!

Most in vitro models lack the capacity to fully probe bacterial phenotypes emerging from the complex interactions observed in real-life environments. This is particularly true in the context of...
