Rensselaer Polytechnic Institute’s Gwo-Ching Wang, Ph.D., Travelstead Institute Chair, is the 2025 recipient of the Davisson-Germer Prize in Atomic or Surface Physics from the American Physical Society (APS). Wang is being honored for “pioneering contributions to the development and use of electron diffraction techniques to study surfaces, growth-front ordering, and two-dimensional materials.”

As Rensselaer Polytechnic Institute celebrates its Bicentennial, we reflect on the many great minds, pioneers, entrepreneurs, and game-changers who are Rensselaer alumni. In 1995, the Rensselaer Alumni Association, with the full endorsement of the Institute Board of Trustees, created the Rensselaer Alumni Hall of Fame to preserve and celebrate the exceptional heritage of alumni accomplishments throughout the years. Honorees are chosen by a selection committee based on reputation, professional achievements, service and career contributions, and uniqueness. Etched glass windows located centrally on the Rensselaer campus honor their accomplishments.

Rensselaer Polytechnic Institute has long been at the forefront of space exploration and discovery. On September 30, that storied legacy met the future at RPI’s Space Science and Technology Day.As part of RPI’s yearlong Bicentennial celebration honoring RPI’s rich history and the promising years to come, this event invited the Capital Region community to hear from alumni, students, and researchers propelling humanity’s space endeavors.

Our nation’s security depends on the effective detection of nuclear materials at our borders and beyond. To address this challenge, Rensselaer Polytechnic Institute (RPI) physicist Moussa N’Gom, Ph.D., is leading research aimed at developing a quantum sensing probe to detect and characterize special nuclear materials precisely and without contact. Special nuclear materials are only mildly radioactive but can be used in nuclear explosives.

Rensselaer Polytechnic Institute’s Heidi Jo Newberg, Ph.D., professor of astronomy; Tom Donlon, Ph.D., a visiting researcher at Rensselaer and a postdoctoral researcher at the University of Alabama; and their team have recently published research that reveals a shocking discovery about the history of our universe: the Milky Way Galaxy’s last major collision occurred billions of years later than previously thought.
