Placido Fernandez Declara is a computing engineer focused on high-performance computing, frameworks and software engineering. During his PhD at the LHCb experiment he developed and improved tracking algorithms for many- and multi-core architectures; he worked on developing the Allen framework with focus on GPU and vectorized algorithms. He received his PhD from University Carlos III of Madrid. Before his Doctoral studies at CERN, he worked on aerospace and high-speed rail industry as a software engineer.

I am an Energy Engineer specialized in Heat Transfer and Fluid Mechanics. During my PhD I have been working on cryogenic cooling systems for superconducting magnets including neon, nitrogen and argon as working fluids. My current position focuses on the design of high-density feedthroughs for liquid argon calorimeters.

I am highly interested in all the technologies related to cryogenics and I am always looking for something new to learn and new devices to develop and test.

I am an experimental physicist with a strong interest in computing and detector development. As a doctoral student, I was already working on the Future Circular Collider Design Study, writing my thesis on track reconstruction with timing information in FCC-hh. Besides allowing me to work on a broad range of interesting topics, my work on the FCC also gave me a sense of the importance  of collaborations in High Energy Physics. So I am glad to continue working on the future of our field, now on the collaborative project Key4HEP with colleagues from CLIC, FCC and CEPC.

Roger Forty studied physics at Oxford and Cambridge universities before gaining his PhD at Imperial College London working on the NA14 experiment at CERN, studying charm production with one of the first silicon microstrip detectors. He then came to CERN as a research fellow working on ALEPH, and has stayed at CERN as a staff member ever since, moving to the LHCb experiment when it formed.  There he helped design the RICH detectors, and proposed a novel detector for low-momentum particle ID known as TORCH that is under study for a future upgrade.
