After postdoctoral studies (2006-2008) at the Lawrence Livermore National Laboratory (Department of Energy) in micro/ nanotechnology as an Ernest Lawrence Fellow, Dr. Chahine developed a new bioengineering and biomechanics research program at the Feinstein Institute for Medical Research in New York.
Her team’s research applies the tools of biomedical engineering to study and develop treatments for degenerate cartilaginous tissues in the musculoskeletal system. Specifically, their research is focused on the intervertebral disc in the spine, articular cartilage in the joints, and the Achilles tendon. These tissues play a pivotal role in load transmission during locomotion, and their ability to bear load changes with aging and degeneration.
The aim of Dr. Chahine’s research is two-fold: (1) Understand the role of inflammation in the etiology of injury and degeneration. (2) Design biological replacements of diseased cartilaginous tissues that can withstand the biomechanical and inflammatory environment after implantation. Her lab’s approach to this research utilizes hierarchical studies at the joint, tissue, cellular, and molecular level. The ultimate goal of studying the healthy function of tissues and cells is to develop treatments, and potentially cures, for degenerative diseases, such as disc disease and osteoarthritis.
Dr. Chahine’s lab hosts residents from the Departments of Neurosurgery and Orthopedic Surgery for research rotations. Dr. Chahine is an active member of the Bioengineering Division (BED) of the American Society for Mechanical Engineers (ASME) and Orthopaedic Research Society (ORS). She has successfully administered externally funded projects and collaborated with other internal and external researchers to produce several peer-reviewed publications. Dr. Chahine has a demonstrated record of early success and productive research projects in an area of high relevance to our aging population.
Quynhhoa (Hoa) T. Nguyen, PhD
Post Doctoral Fellow
Phone: (516) 562-2545
Hoa received her B.S. from the University of Utah in Biomedical Engineering in 2005. She then attended the University of California San Diego and received a MS and PhD in Bioengineering in 2007 and 2012, respectively (from the lab of Professor Robert Sah). She has previously worked in projects involving mechanobiology and biomechanics of articular cartilage repair. Her current project investigates the effect of inflammation on cell biomechanics and cell deformation in the intervertebral disc. Hoa is also researching the effects of MMP inhibition on tendon healing and tendon biomechanics.
Paula A. Hernandez, PhD
Post Doctoral Fellow
Phone: (516) 562-2534
Paula received her PhD in Molecular, Cell Biology and Neuroscience from the University of Chile in 2007. She has previously worked in projects involving Osteoclast differentiation (UConn) and Cartilage biology and repair (University of Cambridge). She is a cytoskeleton fan and her current project investigates the effect of inflammation, by TLR4 activation, on the architecture of the cytoskeleton in nucleus pulposus. The main goal is to study the relation between cytoskeleton changes and alterations in the biomechanical properties of these cells within the intervertebral discs, focusing in degenerative disc disease.
Kathryn (K.T.) Weber, MD
Clinical Research Fellow
Phone: (516) 562-2541
Originally from Colorado, K.T. received her BA from Colby College, and her MD from Drexel University College of Medicine. She is currently a clinical fellow at the Feinstein Institute for Medical Research, investigating biomarkers and inflammatory responses in intervertebral disc disease. K.T.’s research encompasses IRB approved clinical studies, in collaboration with the Spine Division, Department of Neurosurgery, at Hofstra North Shore-LIJ School of Medicine.
Timothy Jacobsen, MEng
Phone: (516) 562-2534
Timothy, a Long Island native, received his BS and MEng degrees in biomedical engineering from Rensselaer Polytechnic Institute in upstate New York. He is currently a research assistant at the Feinstein Institute for Medical Research where he previously worked as a summer intern. His current research involves investigating the response of the IVD to inflammation on a cellular level, and its role in the etiology of disc degeneration. In his spare time Timothy also volunteers for his local fire department and B.S.A. troop.
Shina Satoh, BS
Shina Satoh is a second year Medical Student at Hofstra North Shore – LIJ School of Medicine. She is currently interested in Physical Medicine and Rehabilitation and had the opportunity to explore this field through a summer research project. She investigated changes in pain and inflammatory cytokines due to epidural injections. She would like to continue exploring the field by integrating basis science and clinical research. Shina received her B.A. in Biological Sciences from Cornell University in 2012.
