Research Interests

My research interest includes use of musculoskeletal ultrasound to improve the management of tendon, cartilage, and meniscus/labrum injuries in active individuals. I explore research topics ranging from biomechanics, anatomy, diagnostic ultrasound, ultrasound-guided surgery to the use of orthobiological agents although my primary research domain is in the realm of tendon injury & healing.
