Lab Personnel

Ranjan Gupta, M.D.
Principal Investigator

Dr. Ranjan Gupta has been elected as an ABC Traveling Fellow, one of the most prestigious orthopaedic awards and honors.

Dr. Gupta received his undergraduate degree from Rensselaer Polytechnic Institute, and his medical doctorate degree from Albany Medical College through the Accelerated Six Year Biomedical Program. He completed a general surgery internship, residency in Orthopaedic Surgery, and an NIH Post Doctoral Research Fellowship at the University of Pennsylvania. Subsequently, Dr. Gupta completed fellowship training in hand surgery/microsurgery at the University of California, Los Angeles, followed by an AO Fellowship in hand surgery/traumatology/shoulder at the University of Berne in Switzerland.

Dr. Gupta is Professor of Orthopaedic Surgery, Anatomy & Neurobiology, and Biomedical Engineering. He assumed the role of Department Chairman on January 1, 2007.

Dr. Gupta's research interest includes both clinical and basic science. He has published studies on topics ranging from rotator cuff injuries to distal radius fractures. He is the director of the Peripheral Nerve Research Laboratory at UC Irvine. This lab is focused on understanding nerve regeneration and Schwann cell control of neural injury. He has recently developed an animal model for rotator cuff injury along with Dr. Thay Lee at the Orthopaedic Biomechanics Lab. He remains also actively involved in kinematic research focused on shoulder arthroplasty and DRUJ stability.

Dr. Gupta's practice is limited to care of the shoulder, elbow, and hand. He has a particular interest in arthritis and minimally invasive shoulder surgery. Other areas of focus include treatment of fractures, degenerative conditions, compressive neuropathies, distal radius malunions, and brachial plexus injuries.


Dr. Tahseen Mozaffar is an Associate Professor of Neurology and Director of the UC Irvine Neuromuscular Program. He is a practicing clinician-scientist, a neurologist, and directs the UC Irvine-MDA ALS and Neuromuscular Center. He is part of a national group of scientists who have identified the active genes in sporadic amyotrophic lateral sclerosis (ALS), a discovery that provides expanded opportunities for developing therapies to treat this chronic, incurable disease.

As a nationally recognized expert in his field, Dr. Mozaffar serves as a principal investigator and co-investigator in clinical trials of novel therapeutic drugs for ALS, as well as other neuromuscular conditions. His research interests focus on the pathophysiology of neuromuscular disorders, encompassing nerve dysfunction and the molecular and cellular aspects of muscle atrophy.

Among Dr. Mozaffar's publications are dozens of original peer-reviewed research articles, book chapters and invited reviews. In recognition of his academic achievements he was recently elected a member of the American Neurological Association; the same year he was also elected a fellow of the American Academy of Neurology. He is currently president of the Orange County Neurological Society; he sits on numerous committees of professional associations and medical research foundations.

Responding to the strong interest in neuromuscular research within the medical community, Dr. Mozaffar is a frequent lecturer, guest speaker and presenter at medical grand rounds, professional meetings and research conferences. He also supports public awareness of advances in neuromuscular research by speaking at gatherings of patients and caregivers.

Dr. Mozaffar is a highly regarded teacher as well as director of the neurology residency program at UCI, and has received many awards for his contributions to the education of neurologists, both at UC Irvine and other institutions. He also acts as an advisor to medical organizations developing novel diagnostic technologies and promising treatments for neuromuscular diseases.


Dr. Steward holds the Reeve-Irvine Chair in Spinal Cord Injury Research at the UC Irvine, and is a Professor in the Departments of Anatomy & Neurobiology, Neurobiology & Behavior, and Neurosurgery. Prior to July, 1999, Dr. Steward held the position of Harrison Foundation Professor of Neuroscience and Neurosurgery at the University of Virginia, and was the Founding Chair of the Department of Neuroscience in the University of Virginia School of Medicine. Dr. Steward's current research focuses on how nerve cells create and maintain their connections with each other, how these "synapses" are modified by experience and after injury, and what genes play a role in nerve cell regeneration, growth and function.


Weiping Wang MD, PhD
M.D. from Tianjin Medical University, China
Ph.D from Kobe University, Japan
Lab Manager

Dr. Wang is a gastroenterologist by training who completed his PhD and postdoctoral research in Japan. As the lab manager, Dr. Wang provides invaluable expertise on molecular biology and cell culture techniques.


Minal is in her third year of orthopedic surgery residency training at UC Irvine. She received undergraduate degrees in political science and molecular biology from UC Berkeley, a masters degree from Boston University, a law degree from UC Hastings, and her medical degree from University of Toledo College of Medicine. At PNRL, Minal is working on projects involving compression neuropathies and nerve transections. She recently was awarded the Orthopedic Research Educational Foundation 2014 Resident Clinician Scientist Training Grant. She also presented the lab's work at the 2013 International Society for Neural Regeneration, where the lab was awarded a Poster Finalist Award.


Dr. Kurimoto hails from Nagoya, Japan where he practices hand surgery at Nagoya University Hospital. He is visiting PNRL for the year where he is researching methods by which to preserve the neuromuscular junction after traumatic nerve injury.


James is a medical student at UC Irvine School of Medicine. He received his undergraduate degree from UC San Diego in Biochemistry and Cell Biology. He is currently working on various projects in the PNRL.


Jared is a second-year Biological sciences major at UC Irvine.

 

Michele is a second-year Biological sciences major at UC Irvine.
