Created in 2009, the LNE Research Prize aims to reward researchers contributing to the success and scientific reputation of the French metrology network it leads and its own research activity. This seventh edition will feature a researcher whose work is complex and international in scope on Tuesday, December 8.
Laurent Pitre, Ph.D. in Physics, is distinguished for his research in the construction of the new international system of units.
He began his career in 1995 at the CNAM where he completed his thesis on the design, realization and characterization of a new type of thermometer below 1 K (-272oC): the second sound thermometer. In 2003 and for a period of two years, he joined theNational Institute of Standards and Technology (NIST) as a visiting researcher. During this period, he designed a new type of spherical resonator for which he received an award in 2005. On his return, he adapted this type of spherical resonator to thermometry (from -269 to 30 degrees Celsius) and for experiments related to the determination of Boltzmann's constant in order to make the measurements traceable over more than 50 years; this is part of a new redefinition of the kelvin. The three major publications on the determination of Boltzmann's constant place the work of the LNE-LCM at the level of 50% in the calculation of uncertainty for the codata on this constant.
His involvement in seven European projects (ULT, ULT2, Boltzmann, INK, NOTED, MeteoMet and MeteoMet2), as well as his various and numerous publications, attest to the recognition of his work on the international scene.
