Education and Professional Experience

  • Ph.D., Civil Engineering, Technical University, Delft, The Netherlands
  • M.S., Civil Engineering, Stanford University, Stanford, CA
  • M.S., Industrial Engineering and Engineering Management, Stanford University, Stanford, CA
  • B.S., Civil Engineering, University of California, Berkeley, CA
Dr. Chinn is the Division Leader of the Materials Engineering Division in the Engineering Directorate.  Sections in the division that Dr. Chinn currently leads span a wide range of materials, process technologies and manufacturing research, including materials testing and characterization, joining technologies, failure analysis, nondestructive evaluation, micro- and nanofabrication, and precision engineering. Technical activities span fundamental research, through development and prototyping, to low-volume specialized production.

Dr. Chinn began her career as a structural engineer, working on the design and analysis of high-rise steel structures, nuclear power piping analysis, and seismic retrofitting. After completing her Ph.D. degree in Applied Mechanics specializing in ultrasonic wave propagation, she worked in nondestructive evaluation at Lawrence Livermore National Laboratory. She has performed experimental and theoretical work in ultrasound, x-ray, and thermal nondestructive evaluation. She holds two patents, one in guided wave testing and one in photothermal microscopy.

Research Interests

Acoustics, x-ray imaging, thermal imaging, signal and image processing, and structural design and analysis
