Pibida, Leticia

Dr. Pibida has been part of the NIST staff for more than 12 years.In the beginning of her carrer at NIST she was the principal investigator for the NIST resonance ionization mass spectrometry (RIMS) system, She is currently the lead scientist for gamma- and x-ray spectrometry measurements using high purity germanium detectors at NIST, that provides activity calibrations and impurity measurements. She is also the project leader for the development of a broad range of American national standards for homeland security applications involving radiation detection. In recognition for her leadership in support of homeland security, Dr. Pibida was awarded the U.S. Department of Commerce Silver Medal in 2004. Dr. Pibida was among the first radiation experts nationwide who helped lead the development of the first four ANSI/IEEE standards for radiation detection adopted by the U.S. Department of Homeland Security (DHS). Following this, she conducted testing of radiation detection instruments at national laboratories throughout the U.S.and at NIST. She designed the first Test and Evaluation Protocols against the newly developed ANSI/IEEE standards that were used by the four national laboratories (PNNL, ORNL, LANL, LLNL) that were chosen by DHS to conduct the testing of a new generation of radiation detection equipment for homeland security applications. This effort led her to work with the Domestic Nuclear Detection Office (DNDO) and the National Voluntary Laboratory Accreditation Program (NVLAP) in the development of the Graduated Radiological /Nuclear Detector Evaluation and Reporting GRaDERSM Program that required the development of a new accreditation program for testing laboratories.

Due to her outstanding initial contribution in support of DHS she was asked by the DNDO to contribute to the testing of the advance spectroscopy portal monitors and various radiation detection systems.As a result of this most recent contribution she has traveled to testing facilities throughout the country to perform measurements, advice and supervise testing methods. She is currently leading the development of technical capability standards for DHS/DNDO.

Dr. Pibida is recognized at the international level for her expertise in metrology and radiation detection measurements. She is the convener of the International Electro Technical Commission (IEC) Technical Committee 45 Working Group B15 for development of standards for detection of illicit traffic of radiological and nuclear materials. She has published more than 40 scientific publications in peer reviewed journals and wrote more than 20 reports and plans for testing the of radiation detection systems for homeland security. She has been invited to give presentations at the different agencies including the IAEA. She has significantly contributed to the development of more than 10 ANSI/IEEE standards documents.
