1/ Why do muscles atrophy with aging and disuse? Is it because each tiny little myofibril gets smaller… or is it because we lose myofibrils? In our new study, we addressed this in humans and mice. biorxiv.org/cgi/content/sh… Full breakdown of the findings in this thread 👇

Excited to share that the first study of my dissertation is now available on bioRxiv! Huge thank you to @CWSundberg, collaborators @KevinMurachPhD @CoryDungan, and everyone else involved for their help with the project! biorxiv.org/content/10.648…

🎉 Please join us in welcoming @Zepeda_CS to the EEP Trainee Committee! 👏 Carlos is a PhD Candidate at @NWSMarquette and joins the committee after receiving the 2025–2026 Porter Physiology Development Fellowship 🏆 We’re excited to have you with us, Carlos! 😊

@LabNarkar @muexrsgradprog Thanks @LabNarkar!

@muexrsgradprog Congrats Carlos!

Congratulations to second year Ph.D. student Carlos Zepeda, along with his mentor Dr. Chris Sundberg, for their co-authored article titled 'Single muscle fibre contractile function with ageing', which was accepted into The Journal of Physiology. #marquetteuniversity #muscle
