Dr. Miguel Viliesid (NACMA, officer)

Dr. Miguel Viliesid has a Bachelors degree in Mechanical Engineering from the Universidad Autónoma Metrolpolitana Azcapotzalco (UAM-A) in Mexico City. He then obtained a Diplôme d'Études Apporfindies (DEA) in Vibrations and Oscillators followed by a PhD in Experimental Modal Analysis from the Faculté de Science et des Techniques de Franche-Comté in France.

Miguel worked for several years at the Insituto de Investigaciones eléctricas (IIE), a research center for the utility industry in Mexico, on projects related to steam generators, piping flexibility and flow induced vibrations in piping.

Miguel joined the Centro Nacional de Metología (CENAM), the National Metrology Institute (NMI) of Mexico since its foundation in 1993, where he has been the head of the Dimensional Metrology Section for already 20 years. He was responsible of the setup of the Dimensional Metrology laboratories, hiring personnel, implementation of the quality system, establishment of measurement capabilities and their related uncertainties being able to prove them through several international comparisons.

Miguel has published papers related to metrology, uncertainty estimation and laboratory comparisons in different international journals. He has also been representing his institute at the Comité Internationale de Logueurs (CCL) from the International Committee of Weighs and Measures (CIPM) since 1997 and has piloted several international comparisons. He joined NACMA since 2007 as the Mexican Vice-chairman for the Mexican Section. He has organized two international conferences of the organization in Mexico (2009 and 2012), and was nominated president of NACMA for the period 2011-2012.
