Tenenblat obtained her MSc (1969) at the Univ. of Michigan and PhD (1972) at the Instituto de Matemática Pura e Aplicada, Rio de Janeiro. She has served in various capacities at the Univ. de Brasilia, Brazilian Mathematical Society, Ministry of Education, Ministry of Science and Technology (Brazil) and other organizations and committees. She is professor emeritus of mathematics at the Univ. de Brasilia. An expert in differential geometry, she has advanced understanding of the interaction between differential geometry and partial differential equations. With S.S. Chern and other collaborators, she helped develop the classification of systems of differential equations that describe pseudo-spherical surfaces. Her membership includes: Brazilian Mathematical Society; American Mathematical Society; Brazilian Academy of Science; and Brazilian Society for the Advancement of Science. She received the Comendador de Ordem Nacional do Merito Cientifico from the President of Brazil in 1996.

Durmus Demir is a faculty at Faculty of Engineering and Natural Sciences, Sabanci University, Istanbul, Turkey. He obtained his Ph. D. in 1995 in Physics from Middle East Technical University, Turkey. Afterwards, he has held post-doctoral positions at the University of Pennsylvania (1996-97), at the ICTP (1998-2000) and at the TPI, University of Minnesota (2000–03). He joined Physics Department of Izmir Institute of Technology in 2003 and worked there until 2019. Demir has been working in particle physics (naturalness, dark matter, CMS experiment at CERN), gravitation (black holes and inflation in emergent gravity), and quantum physics (quantum tunneling time). His research is theoretical and phenomenological. He was Turkey’s representative at CERN’s Strategy Council Meeting in 2006. He was awarded by a number of national institutions. He is the first Turkish-citizen researcher to win the Alexander von Humboldt Foundation Friedrich Wilhelm Bessel Research Award (2007). He is an OIC-COMSTECH Distinguished Scholar (2021). He is in the editorial board of Letters in High Energy Physics journal. He is a member of the CERN-CMS Exp., Science Academy- Istanbul, and TWAS MAC (Physics).
