View full CV here

Christophe Bonnal started his career in 1984 in Aerospatiale, now Ariane Group, dealing with technical topics of the Ariane 4 launcher, then in charge of several future projects (reusable launchers, ATV), before joining the Ariane 5 development team. Christophe moved to the Launcher Directorate of CNES, the French Space Agency, in 1993, still on Ariane 5. After the qualification of the heavy European launcher in 1998, Christophe was named head of the Future Projects Department. In 2005 he became the Senior Expert of the Technical sub-Directorate, and in 2018 the Senior Expert of the Launcher Directorate, directly attached to the Director. In parallel, Christophe Bonnal has been in charge of the Space Debris topic since 1987 and is currently French delegate to ISO and IADC.
Member of IAA, Christophe is the co-chair (with J-C. Liou) of the IAA Space Debris Committee. Member of AIAA, Emeritus of French 3AF, Member of AAE (Air & Space Academy). Co-Editor of Acta Astronautica, CEAS Space Journal and AIAA Journal of Spacecraft and Rockets.


Dr. Carolin Frueh

Associate Professor at the School of Aeronautics and Astronautics, Purdue University

Dr. Frueh is Associate Professor at the School of Aeronautics and Astronautics, Purdue University. Dr. Frueh holds a PhD in Physics with a Specialization in Astronomy, from the University of Bern, Switzerland and was a National Research Council Postdoc with the Air Force Research Laboratory, Kirtland Air Force Base and a Research Scientist with the Aerospace Department at Texas A&M University. August 2014, Dr. Frueh started at an Assistant Professor at Purdue University, Aeronautics and Astronautics Department, since 2020 Dr. Frueh holds the rank of Associate Professor there. Dr. Frueh is the chair of the COSPAR Panel on Potentially Environmentally Detrimental Activities in Space (PEDAS). Research interests are Space Situational Awareness, Space Traffic Management, object characterization and astrodynamics, sensor fusion and information retrieval in data deprived regions in the near-Earth and cislunar space. Dr. Frueh has published more than  100 research papers.


Dr. Darren McKnight

Senior Technical Fellow, LeoLabs

Dr. Darren McKnight is currently Senior Technical Fellow for LeoLabs.  Darren leads efforts to realize the value proposition for the growing global network of ground-based radars for space situational awareness, space safety, and space sustainability. He creates new data depictions, develops risk algorithms, and leads space incident investigations. He is focusing on creating new statistical collision risk assessment approaches to provide valuable context to the operational collision avoidance support provided by LeoLabs worldwide.

As a member of the International Academy of Astronautics’ Space Debris Committee, he has been active in position paper development, selection of symposia papers, and execution of the annual International Astronautical Congress. His current focus is on developing technical solutions and encouraging global behavior that leads to sustained space operations assurance through limiting the risk of debris collision hazard to space systems in Earth orbit. Recent efforts have shown that the greatest debris-generating potential in low Earth orbit comes from the thousands of massive derelict objects deposited over the last 50 years and not from the recent proliferation of smallsat constellations.

He has coauthored five books ranging from space debris and spacecraft operations to soccer coaching and innovation. Darren has authored over 100 technical papers and presented them in 16 countries including guest lectures at nine universities globally.

Darren received his bachelor’s degree from the United States Air Force Academy in Engineering Sciences, his master’s degree from the University of New Mexico in Mechanical Engineering, and his doctorate from the University of Colorado in Aerospace Engineering Sciences.


Professor Arun K. Misra

Thomas Workman Professor, Department of Mechanical Engineering, McGill University

Arun K. Misra is the Thomas Workman Professor in the Department of Mechanical Engineering at McGill University in Montreal, Canada. His research interests are in the areas of satellite dynamics and control, space debris, space robotics, and fluid-structure interaction. He is a Fellow of the American Institute of Aeronautics and Astronautics (AIAA) as well as of the American Astronautical Society (AAS). He has been elected to the Canadian Academy of Engineering and to the International Academy of Astronautics. He is a Co-Editor of the international journal Acta Astronautica. He has received a number of awards and honors including the Dirk Brouwer Award from the American Astronautical Society.






Cristina Perez Hernandez

Technical Officer for the SST Programme, CDTI 

Cristina Perez holds an Engineering Degree (MSc 5-year degree) in Aerospace by Politechnical University of Madrid, including a Master Thesis “Optimization of impulsive Maneuvers using Genetic Algorithm" by Universitá dello Studio della Sapienza, Rome. She has been working in the space domain since near 15 years, at the beginning in close cooperation with the Spanish Ministry of Defense, working on the programmatic and industrial aspects of Spanish space Programs and finally,  she joined CDTI in 2016 as Technical Officer for the SST programme. She is the Spanish delegate in the EU SST Technical Committee and regarding her experience in conjunction analysis she is currently  the Head of Operations and Services of the Spanish Space Surveillance and Tracking Operation Center (S3TOC). The S3TOC is in charge of the CA service provision, together with the FR OC, in the EUSST Service Provision Model.
