Nicholas J. Gryfakis, MS, Manager/biomedical engineer
Nick joined the Motion Analysis Center staff in 2002 after working as a mechanical project engineer at General Motors Corporation. He earned his undergraduate degree from Northern Illinois University in mechanical engineering and then continued his education at the graduate school of Northwestern University, earning his MS in biomedical engineering in 2001 with a focus in biomechanics. Along with Nick's current research projects at the Motion Analysis Center, his research has been presented at national conferences such as the American Academy of Cerebral Palsy and Developmental Medicine (AACPDM) and the Gait & Clinical Movement Analysis Society. Additionally, he has co-taught instructional courses at the AACPDM in the area of orthopaedic management of spina bifida.

Claudia Kelp-Lenane, Physical therapist
Claudia Kelp-Lenane is a senior physical therapist who has worked in the Motion Analysis Center since 1991 and in the physical therapy department at Children's Memorial Hospital since 1977. Claudia graduated from the University of Iowa and gained experience in Ann Arbor, Michigan, as well as the Salisbury Health District and King's College Hospital in London, England. Additionally, she has maintained a private practice in physical therapy over the past several years. One of Claudia's specialty is the treatment of children with neuromuscular disorders. She has shared her extensive knowledge in the use of gait analysis for the treatment of children with myelomeningocele by teaching instructional courses at national conferences such as the American Academy of Cerebral Palsy and Developmental Medicine (AACPDM). Furthermore, Claudia has co-authored two chapters in the book, Caring for the Child with Spina Bifida (2001), and has participated in several research projects within the Motion Analysis Center adding several abstracts and papers to her name. Claudia is also the Sports Biomechanics Program physcial therapist in the Motion Analysis Center.

Melissa Colthrust, MS, Kinesiologist
Melissa joined the Motion Analysis Center in 2006 after earning a Master of Science degree in Biomechanics from Ball State University, Indiana. Prior to graduating, Melissa worked as a Research Assistant at the Ball State Biomechanics Laboratory. She completed research on the effect of hormone levels on knee stiffness in women. Currently, Melissa serves as the Kinesiologist at the Motion Analysis Center.

Laura M. Johnson, MS, Biomedical engineer
Laura joined the Motion Analysis Center staff in 2006 after working as a research assistant in the Falk Neurorehabiliation Lab at Marquette University. She earned both her undergraduate and graduate degrees from Marquette University in biomedical engineering with an emphasis on biomechanics and graduate work in neurorehabilitation. Her research interests there were focused on arm biomechanics and robotics in rehabilitation. Her research and publications have been presented at numerous national and international conferences.
