Last week, I presented my research at ClostPath 2025 at the Pasteur Institute in Paris. It was wonderful to share my work on polymicrobial interactions in the gut microbiome and hear from others also studying Clostridial pathogens. Thank you to the conference organizers for this amazing opportunity!

I’m excited to share my recent study from the labs of @joeyzacks.bsky.social and @ritatamayo.bsky.social on the impact of E.faecalis on phase variable behaviors in C.difficile. This work was achieved through amazing co-leadership with PhD candidate Jilarie Santos-Santiago.
