She has published a number of scientific papers, including a book chapter on the effect of workplace interventions to prevent and treat low back pain, and has presented her work extensively. She is a member of the Norwegian Association of Researchers and serves as a board member with the Norwegian Society of Behavioural Medicine.
 
Upon completion of her tenure in 2010, she returned to Norway to resume a post-doctoral assignment with the Department for Health Promotion and Development at the University of Bergen.
Timothy J. Wright, Ph.D.
Affiliation: University of Massachusetts-Amherst

Dr. Wright collaborated with the Center for Behavioral Sciences in the area of transportation research. During his tenure, he investigated age-related factors that influence the use of driverless vehicles (also known as self-driving or autonomous vehicles) and how these factors influence the drivers’ ability to take control when the automated system requires manual operation.
 
Previously, Dr. Wright worked as a pre-doctoral researcher at Florida State University. His research interests span basic and applied aspects of attention including how aging influences attention and other cognitive abilities. He studied the factors that capture attention in visual scenes and also the factors that determine what goes unnoticed in these scenes. He also investigated the extent to which driving distractions can impair both older and younger drivers, how training can mitigate age-related attentional and cognitive declines and the effectiveness of interventions designed to combat these declines.
 
While at University of Massachusetts-Amherst, Dr. Wright served as a post-doctoral research associate. He earned his M.S. and Ph.D. in cognitive psychology at Florida State University in 2013 and 2015, respectively. A member of the Vision Sciences Society, he also served as a reviewer for Journal of Experimental Psychology: Human Perception and Performance, Attention, Perception, and Psychophysics and the Journal of Gernontechnology. Since 2011, his work was acknowledged through numerous awards and fellowships from the American Psychological Association, Florida State University and Florida State University’s affiliated University Transportation Center. He has published 11 peer-reviewed journal articles and book chapters, and his work has resulted in nearly two dozen professional conference presentations.

Upon completion of his tenure, Dr. Wright took a postion with Dunlap and Associates, Inc. in Stamford, CT.
Xu Xu, Ph.D.
Affiliation: Harvard School of Public Health
 
Dr. Xu collaborated with research scientists from the Institute’s Center for Physical Ergonomics to investigate 2D and 3D lifting models used in the development of video-based lifting exposure assessment methods. The study proposed a new method to estimate joint loading on a worker’s body during manual materials handling tasks. The new method, based on a model previously developed at the Research Institute, can assess the risk of overexertion for more complex lifting tasks using videotape recordings from the field.
 
Dr. Xu's research interests include occupational biomechanics, upper extremity modeling, gait analysis and multivariate statistical analysis. Previously, he served as a teaching assistant at North Carolina University. He earned his Ph.D. and M.S. degrees from the North Carolina State University, Raleigh and his B.S. from Tsinghua University, Beijing, China. A member of the Human Factors and Ergonomics Society, he has served as a guest reviewer with Accident Analysis and Prevention, IEEE Transactions on Systems, Man and Cybernetics, Ergonomics, and Human Factors.
 
Dr. Xu completed his tenure in 2010, and accepted a position as a research scientist with the Institute's Center for Physical Ergonomics.
Yusuke Yamani, Ph.D.
Affiliation: University of Massachusetts-Amherst
 
Dr. Yamani worked with the Institute’s Center for Behavioral Sciences in the area of transportation safety. His research aimed to explore older drivers’ safety at intersections. During his tenure, he examined relationships between normal aging, visual scanning patterns and motor control of the vehicle. His research interests include attention mechanisms and how they constrain human performance in basic and applied environments.
 
Prior to his tenure as a post-doctoral fellow, Dr. Yamani was a graduate student researcher, instructor and teaching assistant at the University of Illinois at Urbana-Champaign. He is a member of the Human Factors and Ergonomics Society and the American Psychological Society, and serves as an ad hoc reviewer for Human Factors, Computer Human Interaction and IEEE Transaction on Human-Machine Systems. With seven published articles, he has also presented his work at a number of professional conferences.
 
In 2013, Dr. Yamani received his Ph.D. in psychology from the University of Illinois at Urbana-Champaign. His dissertation focused on people’s ability to divide attention across the visual field and how it changes across lifespan. At the University, he also received his M.S. in human factors in 2010. He graduated with a B.A. in psychology and philosophy from the State University of New York at Geneseo.
 
After completing his fellowship in 2014, Dr. Yamani accepted a faculty position at Old Dominion University.
