Douglas Smith, MD

Douglas H. Smith serves as Director of the Center for Brain Injury and Repair (CBIR) and is the Robert A. Groff Endowed Professor and Vice Chairman for Research and Education in Neurosurgery at the University of Pennsylvania. Penn's multi disciplined CBIR includes over 25 principal investigators and their laboratory staff collectively studying mechanisms, diagnosis and potential treatments of traumatic brain injury.

Dr. Smith is also director of a multi-center U.S. National Institutes of Health (NIH) program grant on mild traumatic brain injury and oversees an NIH brain injury training grant. Over the last 20 years, Dr. Smith has devoted his full-time efforts to neurotrauma research following completion of fellowships in both molecular biology and neurotrauma at the University of Connecticut. His laboratory investigates the effects of mechanical stretch of axons that results in either damage or growth. He has found that rapid stretch during brain trauma selectively injures axons in the white matter. In turn, aberrant accumulation of proteins in the damaged axons can lead to pathologic changes similar to those found in Alzheimer's disease. In addition, Dr. Smith's laboratory has also recently discovered that slow continuous stretching of axon tracts in culture can stimulate enormous growth, creating transplantable living nervous tissue constructs. These tissue engineered constructs have shown promise for repairing large lesions in the nervous system. These collective efforts have resulted in over 150 published reports.

Kevin Caparino, BS

Kevin is a MSE candidate in Bioenegineering at Penn, having received his BS in Biomedical Engineering at Rutgers, New Brunswick.  His research background and interests are in scaffold design and biomaterials in regards to tissue engineering, and is currently helping Dr. Smith investigate a possible means of synaptogenesis.

Natalie Giovino, BS

In May 2017, Natalie received a BS in chemistry from Haverford College with a concentration in biochemistry.  Her undergraduate thesis involved working with peptide hydrogels.  In August 2017, Natalie started a master's program in bioengineering at the University of Pennsylvania.  She is currently working in the Smith Lab on her master's thesis, seeking to better understand traumatic brain injury using induced pluripotent stem cells.

Nimish K. Acharya, MD

Dr. Acharya obtained his PhD in Cell and Molecular Biology from Rutgers University (formerly UMDNJ). His dissertation studies were aimed at understanding the pathophysiology of Alzheimer's disease (AD) and developing blood-based biomarkers for AD diagnosis. He holds a Master's degree in Medical Biochemistry and a Bachelor's degree in Medical Laboratory Technology. Dr. Acharya joined the Smith lab in 2016 and is spearheading a project investigating the formation of intricate neuronal pathways in the developing brain. He is also part of the team investigating the pathophysiology of Traumatic Brain Injury using the Smith Lab's rotational acceleration injury model.

Randel Swanson, DO, PhD

Dr. Swanson is a Physiatrist (Rehab Doctor) specializing in Neurorehabilitation, with a clinical focus on Traumatic Brain Injury. Broadly speaking, Dr. Swanson's research interests surround the mechanisms of secondary neurodegeneration following TBI, and the development of accurate diagnostic and prognostic biomarkers for post-TBI neurodegeneration. Dr. Swanson joined the lab in 2016 after receiving funding (K-award) through the Rehabilitation Medical Scientist Training Program (RMSTP). His RMSTP research aims to investigate the role of IgG-autoantibodies in secondary neuronal injury following TBI. Further, Dr. Swanson will be examining the utility of IgG-autoantibodies to serve as novel biomarkers for advanced TBI diagnostic and prognostic testing.
