Geraldine S. Cheok

Geraldine S. Cheok is a research structural engineer in the Sensing & Perception Systems Group of the Intelligent Systems Division (ISD) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). Ms. Cheok graduated cum laude from the University of Maryland with a Bachelor of Science in Civil Engineering in 1983. She received her Master in Science in Civil Engineering from the University of Maryland in 1986. While working on her graduate degree, Ms. Cheok joined the National Institute of Standards and Technology (NIST) Structures Division in 1984, and has been with NIST since.

Upon joining NIST, she worked for 14 years in the earthquake engineering area, and was mainly involved in the experimental testing and data analysis of model and prototype bridge columns, steel braced frame connections, and moment resisting precast beam-column connections for seismic regions. She also worked on projects involving the seismic response of lightly-reinforced masonry walls and strengthening of lightly reinforced concrete building frames.

Between 1998 and 2012, Ms. Cheok was with the Construction Metrology and Automation Group (CMAG) of the Materials Construction Research Division (MCRD). Her work involved the use of 3D imaging systems (e.g., laser scanners, LADAR, laser radars, range cameras) for construction applications. Her efforts were focused on research, analytical and experimental, that will be used to support the development of standard test methods for 3D imaging systems.

Ms. Cheok was awarded the Building and Fire Research Laboratory's Communicator Award in 1988 and 1997. In 1996, she was named Maryland’s Outstanding Young Engineer. In 1997, she received the American Concrete Institute Structural Research Award. That same year, Ms. Cheok accepted the Department of Commerce Bronze Medal. In 2001, she earned the Department of Commerce Silver Medal. She again received the Bronze Medal in 2004.
