About us
Fernando Posada
Group Leader of the Systems Acceptance and User Environment group at the National Center for Computational Sciences in the Oak Ridge National Laboratory (ORNL). He earned his Ph.D. in Chemistry from the Universidad Nacional de Colombia. During his doctoral studies, Fernando developed an interest in High-Performance Computing and completed a Master’s degree in the same field from the International School for Advanced Studies (SISSA) in collaboration with the International Center for Theoretical Physics (ICTP).
Since then, he has been involved in various HPC projects, working on designing, deploying, managing, and providing support to users in different HPC resources. Before joining ORNL, Fernando worked for six years at Temple University, where he supported and promoted research on on-premises HPC resources and national supercomputing centers through XSEDE/ACCESS.
Richard Berger
Scientist 3 at Los Alamos National Laboratory. His background is in software engineering and optimizing high-performance computing codes, in addition to his degrees in Mechatronics. He is one of the core developers of the open source molecular dynamics code LAMMPS and has contributed to other open source projects such as LIGGGHTS and OpenKIM.
He played an essential role in the procurement, building, and installation of multiple HPC resources on Temple. This includes the Owl’s Nest HPC cluster, which now provides about 6500 CPU cores to the Temple research community.
Moreno Baricevic
Moreno Baricevic is a High-Performance Computing (HPC) specialist based in Trieste, Italy, with over two decades of experience in system administration, software development, and distributed services. Since 2002, he has been a key technical staff member at the National Research Council’s Institute for Materials (CNR-IOM), collaborating closely with institutions such as the International Centre for Theoretical Physics (ICTP) and the International School for Advanced Studies (SISSA). He has participated in ICTP/UNESCO and UNDP initiatives, deploying HPC and ICT solutions in developing countries and providing technical training to researchers in various global settings.
In 2018, he served as “ElectroScience” for the 14th winterover at Concordia Station on the Antarctic Plateau, where he was responsible for maintaining and operating geophysical experiments under harsh conditions, including temperatures as low as -80°C and an altitude of approximately 4,000 meters. In 2021-2022, returned to Antarctica as a “Research Cyberinfrastructure Specialist” for the IceCube Neutrino Observatory at the Amundsen-Scott South Pole Station. During this 13-month assignment, he ensured the continuous operation of the observatory’s systems in isolation with a multinational crew, enduring temperatures down to -70°C and an altitude of about 3,300 meters.
