Orthopaedics & Physical Performance


I specialize in the treatment of hand, wrist, elbow, and shoulder problems. I treat all aspects of hand/wrist, shoulder/elbow, degenerative conditions such as arthritis, reconstruction, as well as peripheral nerve pathologies. My clinical interests includes joint arthroplasty, arthroscopic treatment of hand and upper extremity problems including the rotator cuff of the shoulder, minimally invasive endoscopic procedures as well as microsurgery.

I have served as an Officer in the Cypriot National Guard and in Special Forces Training with the Green Berets. I have also been a martial arts instructor and won awards at national competitions.


I continue to utilize my background in basic science and clinical research to advance the field of orthopedics. I have authored numerous publications and book chapters on topics related to hand surgery, prosthetics, infection and bone grafts, and I frequently present at the national and international levels. I am the recipient of several prestigious awards and honors, as well as research grants. I hold U.S. Patents on implant modification technologies, as well as novel 3D-printed devices that I designed to address hand conditions.

Remaining heavily involved in research, my newest endeavors include utilization of Artificial Intelligence and Machine Learning in the interpretation of medical imaging, automated ultrasound evaluation of scar formation on tendons and I am also investigating the mechanisms of infection establishment on biological tissues.
