Dr. Sergio Ulloa, Professor of Physics and Astronomy, and Dr. Nancy Sandler, Associate Professor of Physics and Astronomy, traveled to Brazil during the 2013-14 academic year to participate in several conferences.:

They will give several lectures at conferences in Brazil in September 2013. They co-organized several of the events, including a special workshop in honor of the 70th birthday of their collaborator Professor Enrique Anda. The title of that workshop is “Musings on Correlated Electron Systems and Life.” Anda is a member of the NSF-CIAM Collaboration, and he is one of Sandler’s and Ulloa’s longstanding collaborators from several previous NSF awards.

Ulloa and Sandler will participate and give lecture during the CIAM Workshop 2013 at the Universidade Federal Fluminense (UFF) in Niteroi, Brazil, Sept. 18-20. His talk is on “Spin-orbit Effects in Real and Artificial Graphene.”

Sandler will present a couple of talks at the CIAM workshop on “Pumping in Low-Dimensional Systems: Graphene as a Case Study” and “Gate Dependent Kondo States in Bilayer Graphene.” The first talk will include an overview of various results from work carried out by Ohio University student Tejinder Kaur, who earned a Ph.D. last July, and a visiting student from Brazil, Daiara Farias, who Sandler co-supervises together with colleague Professor Andrea Latge from the UFF-Niteroi, Brazil.

“This workshop is an approximately biennial meeting we organize among the collaborators of a grant funded by the National Science Foundation to exchange progress reports, visit ongoing collaborative efforts, and brainstorm about future projects,” noted Ulloa. “The collaborators in the United States include Kevin Ingersent at the University of Florida, George Martins at the Oakland University, and Dr. Sandler and I at Ohio University. Abroad, our collaboration includes different researchers in Brazil (Universidade Federal Fluminense, Pontifical Catholic University of Rio de Janeiro, Universidade Federal de Uberlandia, Universidade de Sao Paulo), Argentina (Universidad del Rosario, Universidad de Buenos Aires), and Chile (Universidad de Antofagasta).” In the United States, Sandler is the Project Director.

Ulloa also participated and gave a lecture at Graphene Brazil 2013 in Buzios, Sept. 22-25. His submission on “Spin-dependent Scattering in Graphene: Impurity Characterization and Birefringent Electron Optics” was chosen for an oral presentation at this prominent international event with a number of invited speakers. Graduate student Mahmoud Asmar is the first and main author of the paper, as this is part of his Ph.D. dissertation.

Sandler presented a poster at Graphene Brazil 2013 on “Gate Dependent Kondo States in Bilayer Graphene,” results obtained with post-doc Dr. Diego Mastrogiuseppe.

Sandler also visit the physics department at Universidade Federal do Paraná (UFPR) in Curitiba, on Sept. 26 and give a colloquium on “Magnetoelectric Spin Control in Nanostructures.”



  1. A suggested correction to this article: “Graduate student Mahmoud Asmar collaborated in this work”, is an understatement of the participation of M. Asmar in the project.

  2. David,
    You are correct–and thanks for the note. We have updated the article to reflect that Mr. Asmar is the first and main author of the paper, as this is part of his PhD dissertation. Thank you for bringing this correction to our attention.
