Steven R. Hursh, Ph.D.
IBR President and Chief Scientist

Steven R. Hursh, Ph.D.Dr. Steve Hursh is President and Chief Scientist of the Institutes for Behavior Resources, where he directs research and application efforts on human performance and fatigue, behavioral economics, drug abuse, and cooperative team performance. He is also Adjunct Professor of Behavioral Biology in the Department of Psychiatry and Behavioral Sciences at the Johns Hopkins University School of Medicine. Dr. Hursh's leadership of IBR builds on a distinguished career both as a behavioral researcher and research manager, including 23 years of experience as a scientist in the US Army, serving as the consultant to the Army Surgeon General for Research Psychology, Director of the Division of Neuropsychiatry at the Walter Reed Army Institute of Research, and as a medical staff officer in the Pentagon, Office of the Assistant Secretary of the Army (Research, Development, and Acquisition).

Dr. Hursh is a technical leader of an effort to model the relationship between sleep deprivation and performance. His patented biomathematical model -the Sleep, Activity, Fatigue, and Task Effectiveness or SAFTE™ model- has been accepted by the US Department of Defense as the standard warfighter fatigue model, has been validated and calibrated by the Department of Transportation as a fatigue risk management tool, and is currently used by the Federal Railroad Administration (FRA), the Federal Aviation Administration (FAA), and the Federal Motor Carrier Safety Administration to assess fatigue in transportation operations. He is also the co-inventor of the FAST™ (Fatigue Avoidance Scheduling Tool) and FAST Aviation computer programs used by government agencies and various industries to assess and manage fatigue in operational settings. Dr. Hursh currently serves on the FAA FRMS Review Committee and held a similar position with the FRA.

Dr. Hursh earned his B.A. in Psychology from Wake Forest University and Ph.D. in Experimental Psychology from the University of California, San Diego. He is also a world leader in theory and modeling in the Behavioral Economics subfield of Psychology as defined by the application of economic concepts and metrics to individual and group behavior. Over his 35 years in research, Dr. Hursh has authored or co-authored over 65 published articles, book chapters, and technical reports, and served as associate editor of the Journal of the Experimental Analysis of Behavior.

Robert J. Gerbracht, Ph.D.
Aviation Scheduling Software Expert

Robert J. Gerbracht, Ph.D.Dr. "Bob" Gerbracht has forty-nine years of experience developing applications and performing analyses in the airline, aerospace, defense and civil government industries. He is an expert in the fields of algorithm development, analysis and performance, algorithm optimization for parallel and vector processing, large-scale system architecture and design, analytical and discrete event simulation, operations research, and system performance and tuning. Dr. Bob has a demonstrated ability to apply a broad experience level in solving a wide spectrum of problems and to derive innovative original solutions to new problems for which past experience is inadequate to the task. He has been an active leader in the development of airline crew pairing optimizers since 1970 and is the author of four generations of commercially successful pairing and bidline optimization systems.

Dr. Gerbracht supported the FAA with optimization studies, analyses and technical reports for the development of the science-based flight and duty time regulations published as the FAR Part 117 regulations promulgated in 2011 and put into effect on January 4, 2014. In conjunction with IBR, Inc. he conducted a study for the National Airline Counsels of Canada (NACC) in response to proposed Transport Canada (TC) flight and duty time limits, developing and validating a set of possible waivers to the proposed rules that would maintain or even slightly improve the safety risk due to pilot fatigue while simultaneously providing economic benefits to the airlines. With IBR, Dr. Bob developed the SAFTE-FAST Center (SFC), a universal portal that integrates aircrew scheduling data for processing by the SAFTE-FAST fatigue modeling system. At present supporting three dozen different input file formats, the SFC is used by a number of commercial airlines to bring in data to SAFTE-FAST from nine different legacy systems.

Dr. Timothy F. Elsmore
Author of FAST

Timothy ElsmoreThe author of the original FAST software was the behavioral psychologist and pioneer of laboratory computer science Dr. Timothy Elsmore.

Dr. Elsmore's efforts in software development started with implementation of a laboratory control system on the Digital Equipment Corporation PDP8 computer and touch-screen interfaces for studying primate behavior.

Tim's most lasting and influential achievement was authorship of the Fatigue Avoidance Scheduling Tool - FAST. His flair for data presentation and interpretation was skillfully applied to design the graphical portrayal of performance changes in FAST. The original program was written for the US Air Force under a Small Business Innovative Research grant to NTI. He was assisted in that process by Drs. Steven Hursh and Douglas Eddy, but the fundamental design decisions and architecture originated with Tim and they have endured to this day in the version integrated with SAFTE-FAST used by airlines and corporations around the world.

His impact on the science of sleep and performance extend beyond FAST. Dr. Elsmore also wrote the software sold by Ambulatory Monitoring Incorporated to analyze and portray actigraph data, ActionW. Again, his data management and graphic skill set the standard for presentation of activity data.

Tim also pioneered the development of mobile performance assessment with the Palm Pilot-based performance assessment battery, ARES. That system was successfully applied in patients to forecast the onset of migraine headaches and was combined with mobile neural assessment to field assess potential concussive brain injury in football players a decade before it became commonplace.

Tim also developed a laboratory simulation of work and multi-tasking with his programs SynWork & SynWin. This system is sensitive to drugs and sleep deprivation, and permits the investigation of executive function and divided attention.

We thank Tim for his innovations and hard work - his impact on operational fatigue and performance research is broad and enduring. Many thousands of workers enjoy a safer work environment because of the visionary work of Dr. Elsmore.
