Research Interests

Serves as Director of the Pittsburgh Shoulder Institute, with Dr. Mark Rodosky.  My basic science research involves collaborative work with the University of Pittsburgh Orthopaedic Robotics Laboratory (ORL) and the Biodynamics Laboratory (BDL) focusing on cadaveric biomechanical assessment of shoulder instability with development of novel surgical techniques, and in vivo kinematic analysis of surgical treatments and reconstruction for rotator cuff pathology.  My clinical outcomes research focuses on sports related shoulder injuries in addition to complex shoulder pathology including reconstruction and shoulder arthroplasty.  We have presented our research both nationally and internationally. Our research team has received multiple recent awards including the American Shoulder and Elbow Surgeons Cofield Award (2019), Mighell-Frankle Award (2020, 2021), Hawkins Award (2022), the AANA O’Connor Research Award for Best Overall Paper and Diversity Research Award (2023), and the Shoulder 360 Best Overall Poster (2023).  In addition to my clinical and research practice, I serve as the head orthopaedic team physician for Duquesne University and team physician for Pittsburgh Central Catholic High School, Oakland Catholic High School, and Sierra Catholic High School.
