About Dr. Chaudhry

Hans Chaudhry Ph.D., research professor of biomedical engineering has been at NJIT since 1991 after his retirement as Chair of the department of Applied Science in Punjab Engineering College, Chandigarh (India). He has been responsible for bringing together the research faculty at NJIT in the departments of mathematical sciences, biomedical engineering, mechanical engineering, physics, chemistry, UMDNJ, Kessler Institute of Rehabilitation, West Orange, and VA Medical Center, East Orange. This collaborative research resulted in many publications in the fields of postural stability, stress and strain analysis in the cardiovascular system, optimal patterns of wound suturing, low back dysfunction, human fascia, cerebral aneurysm, and  in-exsufflation for respiratory disabilities, in peer reviewed journals of international repute.A U.S. patent (number 6.324,419) for the apparatus titled Apparatus and Method for Non-Invasive Measurement of Stretch was awarded in Nov.27, 2001 to the research team comprising H.Chaudhry; J.Federici; N.Guzelsu, T.Findley & A.Ritter. Dr. Chaudhryhas developed an automation for the U.S. Patented device ‘Anatomical Torsional Monitor’ (ATM) for evaluating the low back dysfunction and further improving this device for low back pain treatment.

Dr.Chaudhry was awarded the 2009 George W. Northup, DO, Medical Writing Award as a lead author of his entire writing team for their article "Three-Dimensional Mathematical Model for Deformation of Human Fasciae in Manual Therapy" which appeared in The Journal of the American Osteopathic Association (JAOA) August 2008 issue. This article was recognized as the best article published in the JAOA in 2008.
