Dr. Jill Heathcock, MPT, PhD formed the infant lab in 2007. She graduated from the University of Dayton with her BS in Exercise Science and Pre-Physical Therapy in 1998. She then went to the University of Delaware where she earned her Master’s in Physical Therapy in 2001 and her PhD in Biomechanics and Movement Science in 2006. She completed her post-doctoral fellowship at the University of Michigan where she studied infant motor development. Dr. Heathcock joined the Ohio State Physical Therapy Division in 2007, when she started the Infant Lab. Dr. Heathcock is a member of the American Physical Therapy Association (APTA), the Society for Neuroscience, the North American Society for the Psychology of Sport and Physical Activity (NASPSPA), and the International Society for Infant Studies (ISIS).
Her scholarship focuses on how young infants learn to use their spontaneous movements to control and interact with their environment. She is specifically interested in developing evidence-based intervention programs for very young infants at risk for long-term movement impairment and disability.
When she was a baby…
Dr. Heathcock’s first few words included “boat.” She first announced this newly discovered word when picking up her father’s shoe and calling it a “boat.” Dr. Heathcock has four children ages 7 through 14 — all have participated in Infant Lab work. In her spare time, Dr. Heathcock enjoys yoga, playing with her four cute kids, reading, going out to dinner and vegetarian cooking. She is currently trying to learn some French (which is not going well). She also plays basketball with her children who constantly ask to play on the two hoops in their driveway.

“When I was a baby…”
I am the youngest of four and my mom had me when she was 36. She had to return to her teaching job in 6 weeks. She said she brought me home, put in my crib and told me that she really needed me to sleep through the night and apparently I did! But then she says she hardly ever got to hold me because my sisters thought I was the best kind of baby doll!

JULIA MAZZARELLA
DPT, PhD Dual Degree Student
Education Background
Julia graduated Summa cum Laude from Skidmore College in 2013, with a B.A. in Neuroscience and Psychology. Following graduation, she spent a year in Gießen, Germany on a Fulbright Grant, where she did research in visual perception at the Justus-Liebig Universität. Julia joined the Infant Lab in 2015 when she began her studies at The Ohio State University. Julia is working toward a Doctor of Physical Therapy degree (anticipated 2018), as well as a Ph.D. in Health and Rehabilitation Sciences.
Primary Lab Responsibilities
Julia is currently in charge of data processing and analysis for the TINS project, comparing upper extremity kinematics infants with neonatal stroke to typically developing infants. She is also assisting with behavioral coding for the SMA project, observing upper extremity movements in typically developing infants and infants with Spinal Muscular Atrophy in a reaching paradigm.
