Dr. Jayson G. Cosme is a theoretical physicist currently working as a professor of physics at the University of the Philippines Diliman. His interested in exploring physics at the interface between quantum optics, cold atomic gases, and solid-state physics. Outside of physics, He enjoy spending time with his wife, watching (e)sports, playing video games, and board games.

Employment: 
• Professor, 2025-Present, National Institute of Physics, University of the Philippines – Diliman
• Associate Professor, 2020-2025, National Institute of Physics, University of the Philippines – Diliman
• Post-doctoral Scientist, 2017-2020, Institute of Laser Physics, University of Hamburg (Group of Prof. Ludwig Mathey)
• Teaching Assistant, 2014-2017, Institute of Natural and Mathematical Sciences, Massey University
• Instructor, 2012-2013, National Institute of Physics, University of the Philippines – Diliman

Dr. Jayson Cosme is an Associate Professor of the National Institute of Physics (NIP) at the University of the Philippines (UP). He is currently the Program Coordinator of the Theoretical Physics Group and the principal investigator of the Theory of Quantum Fluids subgroup.

Dr. Cosme obtained his BSc and MSc in Physics (2007-2013) at the University of the Philippines – Diliman. He obtained a PhD in Physics (2014-2017) under the supervision of Prof Joachim Brand at Massey University, New Zealand. He then moved to the University of Hamburg, Germany (2017-2020) as a postdoctoral scientist in the group of Prof Ludwig Mathey. His expertise is in theory of condensed matter with a special focus on out-of-equilibrium phenomena, such as the dynamical control and emergence of dynamical phases.

Dr. Cosme retuned to NIP as an Associate Professor and a UP Balik-PhD awardee in 2020. There, he established the Theory of Quantum Fluids research group, and their research focuses on discovering and understanding novel dynamical behavious in various condensed matter systems, such as cold atoms and superconductors. In 2023, he was awarded the first prize in the National Academy of Science and Technology, Philippines Talent Search for Young Scientists for his work on time crystals publsihed in the journal “Science”.
