Pedro Vaz, Ph.D. in Physics, is Coordinator Researcher at IST (Instituto Superior Técnico, the leading Portuguese University of Engineering, Science and Technology, at the University of Lisbon). He is currently member of the Group of Experts (GoE) under Article 31 of the EURATOM Treaty and nominated Portuguese expert at the EURATOM Programme Committee - Fission (CCE-FISSION) of the European Union. He was President of the Center for Nuclear Sciences and Technologies (C2TN) of IST during the period 2017-2020 and Coordinator of the Radiological Protection and Safety Group at IST. He was a member of the Portuguese Group of Experts created to define (in 2018-2019) the national priorities and strategies for the "Horizon Europe" - the European Union research and innovation framework programme 2021-2027. Served as the National Liaison Officer (NLO) of Portugal for the International Atomic Energy Agency (IAEA), between July 2017 and August 2018. Pedro Vaz is/has been Portuguese Representative in several high-level Committees of the European Union (namely the Group of Experts in Radiological Protection of the EURATOM Treaty and the Consultative Committee on Energy Fission of the European Union) and of the OECD Nuclear Energy Agency (Steering Committee for Nuclear Energy, Nuclear Science Committee, Committee on Radiological Protection and Public Health). Pedro Vaz is a member of the Editorial Board of the journal European Journal of Radiology (EJR, Elsevier), section “Radiation Protection and Physics” and Associate Editor (Radiation Physics) of the journal Radiation Physics and Chemistry (RPC, Elsevier). He regularly acts as reviewer of manuscripts of different international journals with peer reviewing. He is the Portuguese or institutional representative in the Boards of different European Union Technology Platforms such as MELODI (Multidisciplinary European Low Dose Initiative) and EURADOS (European Radiation Dosimetry Group). He participates in international scientific consortia Collaborations at CERN, Geneva, Switzerland, undertaking nuclear data experiments and performing Radiation Protection, Radiation Safety, Dosimetry and Shielding assessment of Nuclear Technology facilities. He has participated in several European projects in the fields of transmutation of nuclear waste, radiological and nuclear emergencies, Radiation Protection and Dosimetry, medical applications of ionizing radiation and Education and Training in Radiological Protection. Has been Administrator at the Nuclear Energy Agency (NEA) of the OECD, at the Computer programs Service of the Data Bank. During that time has acquired extensive experience in Monte Carlo, deterministic and hybrid computational methods and nuclear data, in support of peaceful applications of nuclear energy and nuclear technology and served as Scientific Secretary of international Expert Groups such as SATIF (Shielding of Accelerators, Targets and Irradiation Facilities). Is a member of the American Nuclear Society (ANS) and has served as member of the Executive Committee of the Radiation Protection and Shielding Division (RPSD/ANS) and as vice-Chair of the Computational Medical Physics Working Group (CMPWG). He is author/co-author of approximately 480 articles published in international journals with peer reviewing and in Conference Proceedings. Pedro Vaz teaches Radiation Protection and Dosimetry topics in different Portuguese Universities. Was/is supervisor of a dozen PhD thesis (3 ongoing) and a few tens of MsC thesis. Main components of work: Radiological Protection and Radiation Safety, Radiation Dosimetry and Radiation Shielding. Dosimetry of the medical applications of ionizing radiation. Monte Carlo simulations using voxel phantoms. Emerging and innovative Nuclear Technology concepts.
