ROGERS, MN — North Star Imaging hired Valentina Aloisi as the new metrology product innovation manager.

Aloisi completed her PhD program in mechanical engineering from the University of Padova, Italy. Her PhD focused on industrial computed tomography for coordinate metrology, establishing traceability and enhancing the accuracy of X-ray CT dimensional measurements, and determining the sources of errors in CT metrology.

Her research covered several aspects of metrology such as coordinate metrology, surface metrology, measurement uncertainty and measurement traceability. Specifically, her research addressed the study of task specific CT measurement uncertainty; the effects of surface roughness on CT dimensional measurements; metrological performance verification of CT systems using conventional and helical scanning trajectories; and the effects of CT system geometrical errors.

Aloisi’s background is on production engineering and industrial metrology. She obtained her master’s and bachelor’s degree in mechanical engineering from the University of Padova.

During her studies, she gained experience in dimensional and surface metrology, including the use of coordinate measuring machines (tactile and non-contact CMMs), as well as optical and contact profilers.

She holds a CMTrain – Level 2: CMM – Operator certification and has actively been working in the field of CT and metrology since her master thesis.
She is the author of several peer-reviewed journal papers and conference papers on computed tomography and metrology. She has also co-authored a book chapter on computed tomography, along with presenting her research contributions at major conferences and symposiums in Europe and the United States.
