Princeton Engineering Anomalies Research Program




The Princeton Engineering Anomalies Research (PEAR) program was established at Princeton University in 1979 by Robert G. Jahn, then Dean of the School of Engineering and Applied Science, to pursue rigorous scientific study of the interaction of human consciousness with sensitive physical devices, systems, and processes common to contemporary engineering practice. Since that time, an interdisciplinary staff of engineers, physicists, psychologists, and humanists has been conducting a comprehensive agenda of experiments and developing complementary theoretical models to enable better understanding of the role of consciousness in the establishment of physical reality.


  • Robert G. Jahn, Program Director
          Emeritus Professor of Aerospace Sciences and Dean of the School of Engineering and Applied Science who has taught and published extensively in advanced space propulsion systems, plasma dynamics, fluid mechanics, quantum mechanics, and engineering anomalies.

  • Brenda J. Dunne, Laboratory Manager
          Formally trained as a developmental psychologist but regards herself as a generalist whose principal task is the integration of the multiple scholarly vectors that bear on PEAR's various activities.

  • York H. Dobyns, Analytical Coordinator
          A theoretical physicist who designs and implements PEAR's data processing and analytical strategies, and contributes to the development of its theoretical models.

  • Lisa Langelier-Marks, Administrative Assistant
          Maintains the general office and financial framework that permits PEAR's many program operations to function in a systematic fashion. In addition, she assists with the design, implementation, and maintenance of a database management program.

  • Elissa Hoeger, General Factotum
          Provides a broad range of logistical support for all other staff members, including copyediting all of PEAR's publications.

  • G. Johnston Bradish, Technical Coordinator
          An electrical engineer who designed, constructed, and maintained many of the PEAR experimental facilities, and continues to service them on an as-needed basis.

  • Arnold L. Lettieri Jr., Communications Director
          Formally trained in counseling and education. From 1997 to 2003, his principal responsibilities involved overseeing PEAR's contacts with the media, as well as interacting with individuals and organizations who expressed professional or personal interest in our work.

  • Roger D. Nelson, Operations Coordinator
          An experimental psychologist whose long PEAR experience in experimental design, statistical modeling, and data interpretation continues to supplement our ongoing efforts.
