    Dr. Andarawis-Puri is an Assistant Professor in the Leni and Peter W. May Department of Orthopaedics at the Icahn School of Medicine at Mount Sinai in New York City. She graduated from Columbia University with a B.S. in Biomedical Engineering, and then completed her Ph.D. from the University of Pennsylvania in Bioengineering, specializing in Biomechanics, with Dr. Louis Soslowsky as her graduate mentor. Following her graduate studies, Dr. Andarawis-Puri joined Dr. Evan Flatow for her post-doctoral training in the Department of Orthopaedics at Mount Sinai School of Medicine. Dr. Andarawis-Puri became independent faculty in the Orthopaedics department at Icahn School of Medicine in January 2012.


    Dr. Andarawis-Puri’s work in tendon research spans both basic science and translational applications. Much of her earlier work focused on healing of the tendon into the bone. Under the advisement of Dr. Louis Soslowsky at the University of Pennsylvania, her pre-doctoral work evaluated the mechanical environment in the rotator cuff associated with a single tendon tear. Human cadaveric shoulders were used to investigate whether mechanical compensation by a non-injured tendon exists to potentially shield an injured tendon from further injury. Using strain mapping and texture correlation algorithms, this work established that the injured supraspinatus tendon and the intact infraspinatus tendon mechanically interact such that conditions that increased strain in the supraspinatus tendon (pre-disposing it to further injury) also increased strain in the infraspinatus tendon. Subsequently, she joined Dr. Flatow at Mount Sinai for her postdoctoral training to gain experience in establishing in vivo animal models and investigate the molecular and histological component of tendon injury. Their in vivo rat patellar tendon model of fatigue damage accumulation allows rigorous investigation of mechanisms of tendon degeneration. During her postdoc, she identified mechanical parameters that can non-destructively serve as indices of the damage state of the tendon that are predictive of the molecular, mechanical and structural response of the fatigue damaged tendon, over time. Their data also showed that certain matrix remodeling proteins are upregulated 1 week post loading until a certain initial tendon elongation threshold was reached, after which they shutdown, potentially explaining the inability of tendon to effectively repair accumulated damage. Findings from her postdoctoral work in conjunction with data that suggests that tendon healing does not effectively restore native properties, motivated a shift in her research focus after her postdoctoral training to promoting regenerative healing (scar free and with restored native tissue properties) in adult lacerated tendons. The current focus of Dr. Andarawis-Puri’s work is to promote scarless repair in tendons that results in restoration of their native mechanical function. In addition, since compensation by other components of the joint can help protect the tendon from further injury, and allow for an environment that is more conducive to allow the injured tendon to heal, the effect of injury to one tendon on overall joint mechanics is also evaluated.
