Luke Mattar, PhD

Post-Doctoral Researcher  

Luke Mattar is a Bioengineering post-doctoral researcher in the Orthopaedic Robotics Laboratory and his work was supported by a National Institutes of Health grant. Luke graduated from the University of Connecticut with a Bachelor's of Science in Biomedical Engineering with a concentration in Biomechanics. Luke's work is focused on predicting the outcome of exercise therapy for treatment of rotator cuff tears based upon in vivo kinematic analyses and various other parameters.

Jumpei Inoue, MD

Post-Doctoral Researcher

Jumpei Inoue is an orthopedic surgeon from Nagoya City University in Japan. His research interests are shoulder biomechanics using the robotic system and ultrasound. His current research focuses on individual capsule repair based on non-recoverable strain after glenohumeral joint dislocation.

Svenja Hoger, MD

Research Fellow  

Svenja Höger is currently a research fellow in the Orthopaedic Robotics Laboratory from Germany. She is a second year resident in the Orthopaedic Department to the Technical University in Munich. Her current work is focused on the bony morphology of the knee with regard to the morphology the quad tendon.

M. Enes Kayaalp, MD

Post-Doctoral Research Fellow, Associate Professor

Enes is an orthopedic surgeon from Istanbul, Turkey. He is also a member of the editorial team of KSSTA (Knee Surgery, Sports Traumatology, Arthroscopy). He is interested in arthroscopic surgery around the knee and sports medicine. His research interest focuses on the association of knee morphology and ligaments, biomechanics and meniscus.

Zach Herman, MD

Orthopaedic Surgery Resident

Zach Herman is a second year Orthopaedic Surgery resident at the University of Pittsburgh Medical Center training to become an Orthopaedic Surgeon. His current work includes looking at effect of shoulder dislocation and correlating glenohumeral surface area with non-recoverable strain. 

Gillian Ahrendt, MD

Orthopaedic Surgery Resident

Gillian is a second year Orthopaedic Surgery resident at the University of Pittsburgh Medical Center training to become an Orthopaedic Surgeon. She is currently working on shouldering dislocation project to correlate capsule surface area and non-recoverable strain.

Mark Morgan

Undergraduate Student Researcher

Mark Morgan is a second-year undergrad in the Bioengineering department at the University of Pittsburgh. He is a research assistant currently helping with studying shoulder dislocations by tracking non-recoverable strain on cadaveric models. Mark is most interested in prosthetic development and is researching biomechanics to expand his understanding of joint and tissue function.

Ryan Fry

Undergraduate Student Researcher

Ryan Fry is an undergraduate bioengineering student at the University of Pittsburgh. Ryan’s current work in the Orthopaedic Robotics Laboratory is focused on creating 3D models of the glenohumeral capsule to track surface area changes and resultantly improve repair procedures. In the future, he plans on working in the medical device industry.
