Marcelo Byrro Ribeiro is Associate Professor of the Physics Institute, Universidade Federal do Rio de Janeiro - UFRJ. He obtained a BSc in physics (1984) from the UFRJ, an MSc in astrophysics (1987) from the National Observatory, Rio de Janeiro, and a PhD in relativistic cosmology (1992) from the University of London.

From 1992 to 1997 he carried out research and taught graduate courses at National Observatory, but by 1997 he moved to the Federal University of Rio de Janeiro, first as Visiting Professor (1997-1998), then as faculty, Lecturer (1998-2009) and Associate Professor (since 2009), where he has been ever since doing research and teaching graduate and undergraduate courses, except in 2001-2002 when he spent one year at the Vatican Observatory Research Group, Steward Observatory, University of Arizona.

During his PhD he worked under the supervision of Malcolm A. H. MacCallum (picture), developing research in relativistic cosmology. Upon returning to Brazil he continued his research in theoretical cosmology, but after his year in Tucson, Arizona, where he worked with William R. Stoeger (1943-2014), of the Vatican Observatory Group, his research developed a growing emphasis in observational cosmology. Lately he has expanded his research interests to include econophysics and complex systems dynamics. He is also interested in philosophical aspects of modern science, particularly in topics related to cosmology, economics and econophysics.

He has published several research papers, reviews and book chapters on cosmology, econophysics and history and epistemology of science. He has also supervised several students.

He is a member of the following learned societies:

  1. International Society on General Relativity and Gravitation
  2. International Astronomical Union
  3. Brazilian Physical Society
  4. Brazilian Astronomical Society
  5. World Economics Association
  6. Complex Systems Society
