  • Biography

    Joaquín Rodríguez-López is an assistant professor of chemistry at the University of Illinois at Urbana-Champaign. Originally from Mexico, he performed undergraduate studies with Prof. Marcelo Videa at Tecnológico de Monterrey, obtained a Ph.D. at the University of Texas at Austin with Allen J. Bard and did a postdoc with H.D. Abruña in Cornell University. Joaquin’s group combines interests in electroanalytical chemistry and energy materials by developing chemically-sensitive methods for studying ionic and electronic reactivity in nano-structures, highly-localized surface features, and ultra-thin electrodes. An emerging investigator, Joaquín aspires to build a dynamic group that creates original concepts for high-performance energy technologies.
