Office of the Director, NICHD


Lipsett Auditorium, Clinical Center (Building 10), NIH Main Campus, Bethesda, Maryland


The NICHD Director’s Lecture Series features cutting-edge science central to the Institute’s mission. The forum also allows for interaction between staff and other attendees with nationally recognized scientists.

The second lecture in the 2012 Series features Richard M. Greenwald, Ph.D., co-founder and president of Simbex, Inc., in Lebanon, New Hampshire. Dr. Greenwald is also an associate professor of engineering at the Thayer School of Engineering at Dartmouth College as well as a research affiliate in the department of aeronautics and astronautics at the Massachusetts Institute of Technology.

In his lecture, Dr. Greenwald will focus on the science surrounding sports- and blast-related concussions. His lecture will describe concussion research that measures the frequency, magnitude, and direction of head impacts that athletes face during routine play. These measures are important for identifying and understanding the range of injuries that produce reportable signs and symptoms of concussion and measurable brain tissue injury associated with the clinical diagnosis of concussion. He will also discuss the factors that help diagnose concussions in the sports setting and as a function of sport: gender, age, player demographics, playing position, and practice versus game conditions. These factors include head impact exposure, self-reported signs and symptoms, neuropsychological test scores, balance measures, and neuroimaging.

Dr. Greenwald will also detail ongoing research efforts—both independent and collaborative—by other institutions to help identify and quantify the biomechanical basis of mild traumatic brain injury. Dr. Greenwald’s company, Simbex, Inc., developed Head Impact Telemetry (HIT) System technology, with funding through a Small Business Innovative Research award from the NICHD’s National Center for Medical Rehabilitation Research.

The NICHD Director’s Lecture Series is open to the public, and registration is not required. Non-NIH employees should visit for details about getting to the NIH campus and security procedures.

This lecture will not be videocast or archived.
