Wallace Casaca

Professor of Computer Science and Applied Mathematics

He received his Bachelor's degree in Pure and Applied Mathematics and Master of Mathematics degree from UNESP - São Paulo State University in 2008 and 2010. During 2010-2014, he pursued his Ph.D. in Computer Science and Applied Mathematics at ICMC USP - University of São Paulo (advisiors: Luis Gustavo Nonato and Gabriel Taubin). As part of his doctoral studies, he worked as visiting researcher at Brown University and MIT - Massachusetts Institute of Technology. From 2015 to 2016, he conducted researches as a postdoctoral scholar at the Visual and Geometry Processing Group (USP/ICMC, Brazil). His Ph.D. work has been awarded and recognized by several scientific organizations such as CLEI (Latin American Informatics and Computer Science Society), SBC (Brazilian Computer Society), SBMAC (Brazilian Society of Computational and Applied Mathematics) and CAPES (Federal Agency for Support Graduate Education). He participated in more than 80 scientific conferences and he has served as an invited reviewer and a technical member of various international conferences and high-profile journals including IEEE TPAMI, IEEE TIP, IEEE TCSVT, Elsevier CAMWA, etc. He was also invited to join interdisciplinary scientific committees as the Annual Academic Reputation Survey (The Times Higher Education - World University Ranking, organized by Thomson Reuters), Brazilian Applied Mathematics committee, IEEE Societies, among others. He is presently working as a full professor of Computer Science at UNESP - São Paulo State University and UNIVESP - Universidade Virtual do Estado de São Paulo. He is also a member of the Mathematics and Computer Science Graduate Program (Master and Doctoral Advisor) at FCT UNESP - Faculdade de Ciências e Tecnologia, and a research associate at the CEPID/FAPESP ICMC/USP CeMEAI - Center for Research in Mathematical Sciences Applied to Industry. His research interests include data clustering, computer vision applications, computational intelligence, computational geometry, graphics, visualization, optimization, pattern recognition, partial differential equations and numerial methods.
