Herminso Villarraga-Gómez

Herminso is a Physicist and Optical Engineer who specializes in methodologies for industrial applications of X-ray computed tomography (CT) in the areas of dimensional metrology, 3D imaging, and nondestructive testing (NDT). He holds a bachelor’s degree in Physics from the Universidad Nacional de Colombia (National University of Colombia) and a master's degree in Physics from the University of Puerto Rico. Given his particular interests in applied physics, Herminso additionally earned a second master’s degree in Optics from the University of Central Florida. In 2012, he began his doctoral studies with a scholarship from the Center for Precision and Metrology (CPM) at the University of North Carolina, Charlotte (UNCC). Since his experience at the CPM-UNCC, Herminso has been involved in establishing the accuracy and precision of X-ray CT metrology technologies and comparing their performance with other existing measuring techniques, in particular coordinate measurement machines (CMMs). He has worked in collaboration with the National Institute of Standards and Technology (NIST), the National Metrology Institute of Germany (PTB), and Carl Zeiss Industrial Metrology. In 2015, Herminso joined Nikon Metrology, Inc. (USA) to work as an X-ray CT Metrology Specialist. He is a current member of the American Society for Precision Engineering (ASPE), the International societies for Optics and Photonics SPIE and OSA, the American Society of Nondestructive Testing (ASNT), the Society of Manufacturing Engineers (SME), the IEEE Instrumentation and Measurement Society, and other professional associations for engineering and applied physics. In his spare time, Herminso enjoys biking, swimming, and swing dancing, and he also has a passion for farming, particularly cultivating coffee on his parents’ land in the verdant mountains of Colombia.
