Nathan J. Hellyer

Nathan J. Hellyer is an Assistant Professor of Physical Therapy and Senior Associate Consultant at Mayo Clinic's Department of Physical Medicine & Rehabilitation. He holds a PhD in Pharmacology from the University of Iowa, with a thesis on phosphotidylinositol 3-kinase interactions. His research focuses on cell physiology, regenerative medicine, and respiratory muscle biology, with notable work on diaphragm function and protein synthesis mechanisms.

His publications span respiratory physiology (e.g., diaphragm thickness measurements via ultrasound), muscle biology (neuregulin-dependent protein synthesis), and interprofessional education (medical-physical therapy collaboration). He has contributed to understanding denervation effects on muscle proteins and exercise impacts on adolescent growth. His work bridges clinical practice with laboratory research, emphasizing translational applications in physical therapy and regenerative medicine.
