Professor Sara A. Pozzi


Professor, Nuclear Engineering and Radiological Sciences, University of Michigan

Consortium Director, Consortium for Verification Technology

M.S. Nuclear Engineering at the Polytechnic of Milan, Italy, 1997

Ph.D. Nuclear Engineering at the Polytechnic of Milan, Italy, 2001

Professor Sara Pozzi earned her M.S. and Ph.D. in nuclear engineering at the Polytechnic of Milan, Italy in 1997 and 2001, respectively.  She is a Professor and Graduate Program Chair in the Department of Nuclear and Radiological Sciences at the University of Michigan where she established and is the leader of the Detection for Nuclear Nonproliferation Group (DNNG). Her research interests include the development of new methods for nuclear materials detection, identification, and characterization for nuclear nonproliferation, safeguards, and national security programs.

Professor Pozzi is the founding Director of the Consortium for Verification Technology (CVT), a large consortium of 12 universities and 9 national laboratories working together to develop new technologies needed for nuclear treaty verification. In this capacity, she directs the work of 25 faculty members and over 240 students engaged in research projects within the CVT.

Professor Pozzi is the co-author of the Monte Carlo code MCNPX-PoliMi, which is being used at over 50 institutions world-wide. Her publication record includes over 350 papers in journals and international conference proceedings. She was invited to give over 80 seminars, both nationally and internationally. She has graduated 17 Ph. D. students.

She is the recipient of many awards, including the 2006 Oak Ridge National Laboratory Early Career Award, 2006 Department of Energy, Office of Science, Outstanding Mentor Award, 2012 INMM Edway R. Johnson Meritorious Service Award, 2012 UM Nuclear Engineering and Radiological Sciences Department, Outstanding Achievement Award, 2017 IEEE Distinguished Lecturer, and 2017 Fellow, American Nuclear Society.

Dr. Shaun D. Clarke


Associate Research Scientist

M.S. Nuclear Engineering at Purdue University, USA, 2005

Ph.D. Nuclear Engineering at Purdue University, USA, 2007

Dr. Clarke received his Ph.D. in Nuclear Engineering from Purdue University in 2007. Afterwards, he joined the Department of Nuclear and Radiological Sciences at the University of Michigan, where he is currently an Assistant Research Scientist and the Assistant Director of the Consortium for Verification Technology. Dr. Clarke has more than 10 years of experience performing radiation detection measurements and Monte Carlo modeling. He has organized and performed numerous experimental campaigns involving measurements of special nuclear material with organic scintillation detectors and state-of-art digital electronics. His current interests are active interrogation systems for nuclear nonproliferation, safeguards, and treaty verification applications. Dr. Clarke is author or coauthor of more than 120 papers in conference proceedings and peer-reviewed journals.

Dr. Angela Di Fulvio 

OLYMPUS DIGITAL CAMERAAssistant Research Scientist

M.S. Biomedical Engineering at University of Pisa, Italy, 2007

Ph.D. Nuclear Engineering at University of Pisa, Italy, 2011

Dr. Di Fulvio is currently a Postdoctoral Fellow of the Consortium for Verification Technology at the University of Michigan, where her research revolves around the study and development of novel multiplicity counting systems for Nuclear Safeguards.
During three years of Postdoctoral research at Yale University, she developed and experimentally validated superheated emulsion based detectors for homeland security and nonproliferation applications. During her Ph.D research, Dr. Di Fulvio worked at the University of Pisa (Italy) and at the Italian Institute of Nuclear Physics, where she experimentally characterized neutron beams for Boron Neutron Capture Therapy (BNCT) and photoneutron beams. Her research interests also include unfolding algorithms and basic physics of radiation interaction in superheated emulsions. Since 2012, Dr. Di Fulvio is a full member of the European Radiation Dosimetry Group.

Dr. Patricia Schuster

schuster_photoPresident’s Postdoctoral Fellow

M.S. Nuclear Engineering at UC Berkeley, 2013

Ph.D. Nuclear Engineering at UC Berkeley, 2016

Dr. Schuster is currently a President’s Postdoctoral Fellow at the University of Michigan within the NERS department. She completed her PhD at the University of California, Berkeley, where she studied radiation detection materials and instrumentation for a broad range of nuclear security applications. Dr. Schuster’s dissertation research was performed at Sandia National Laboratories in Livermore, CA through the Nuclear Science and Security Consortium.

Dr. Schuster’s dissertation research studied the dependence of the light output and pulse shape in organic crystal scintillators on the direction of the radiation interaction. Her work involved experimental characterization of the effect and the development of a hypothesis for why the directional dependence exists. Dr. Schuster has also studied nuclear security policy, including work on cross domain deterrence as implemented historically by US policy makers.
