Dr. Villarraga has expertise in evaluation of medical device performance during the premarketing and postmarketing stages. She has experience with orthopedic, spinal, plastic and reconstructive surgery, urology, urogynecology, general surgery, women's health, and diagnostic medical devices, with particular emphasis on biomechanics and biomaterial-tissue interactions with medical devices. 

Dr. Villarraga has provided technical support for due diligence, regulatory submissions, regulatory compliance, risk management, postmarketing surveillance, product development, product liability, and intellectual property matters. As a Regulatory Affairs Certified (RAC-US, Devices) professional, Dr. Villarraga uses her knowledge of the U.S. FDA regulations to develop regulatory strategies for novel products, contribute or prepare regulatory submissions, and to support identifying and justifying technical evaluations for pre-market assessments and postmarket compliance matters.

Dr. Villarraga has experience in identifying scientifically justifiable methodologies for assessment of medical device performance, evaluating quality control issues as applied to medical devices and pharmaceuticals, medical device quality systems compliance (gap analysis), contamination, manufacturing compliance, and finished device evaluations. Dr. Villarraga has conducted failure analyses, root cause analyses, and compliance evaluations related to medical device recalls. She has served as an expert witness in product liability and intellectual property cases involving medical devices.

Dr. Villarraga's research experience and interests include spine biomechanics, implant and tissue retrieval analysis, including the use of microscopic (SEM) and tissue analysis techniques (ICP, histology), use of animal models for evaluating orthopedic/spinal device performance, and the use of experimental and finite element stress analysis techniques to characterize the mechanical behavior of bone, other biological structures, and orthopedic/spinal implant devices.

Dr. Villarraga has been a reviewer for the Journal of Biomechanical Engineering, Clinical Orthopedics and Related Research, Clinical Biomechanics, Clinical Neurology and Neurosurgery, and the Journal of Biomedical Materials Research.
