Biography

André Costa Drummond obtained the degree of Computing Engineer from the Pontifical Catholic University of Campinas (PUC-Campinas) in 2002, and in the same year, he started his graduate studies at the Computing Institute of the University of Campinas (IC-UNICAMP), where he obtained the degrees of Master's (2005) and Doctor's ( 2010) in Computer Science. He developed his master's thesis and doctoral thesis in the area of ​​computer networks with an emphasis on traffic engineering for multi-service networks and optical networks.

In his dissertation, he developed mechanisms for self-tuning of bandwidth provisioning in multi-service networks, applicable to the Internet based on the MPLS protocol. These mechanisms promote the re-routing of flows in order to provide the Quality of Service requirements to the applications in multi-service networks. The mechanisms were based on fuzzy optimization. An extensive comparison between effective bandwidth estimators based on measurements was also conducted. The proposed mechanisms were original contributions in the then incipient line of autonomic systems.

André joined his Ph.D. program in August 2004 and directed his thesis to traffic engineering in optical networks, given his participation in the PRONEX project, Nucleus of Excellence in Optical Connectivity. The theme of the thesis is inserted in the efforts of integration between the Internet and optical WDM networks, which serve as the substrate for the same. It is fundamental, in this integration, that the management is achieved through efficient algorithms so that the provisioning of bandwidth can be realized in real-time. His doctoral thesis discussed the construction of such algorithms for RWA (routing and wavelength assignment), dynamic traffic aggregation, and multipath and multi-domain routing problems. He used, first of all, the Parameterized Complexity Theory to solve the problem of coloring in graphs in RWA problems, inaugurating the use of this theory in optical networks to obtain exact and efficient solutions. It has developed efficient algorithms for the aggregation of dynamic traffic, in line with the current reality of Internet traffic. In particular, the concern with the feasibility of using the Internet to compute grids of applications in e-Science has led to the design of routing algorithms for demands that exceed the available capacity of a wavelength, typical of e-Science applications. The proposed algorithms allow the co-existence of these applications with other applications with low bandwidth demand. His thesis work was funded by the CISCO URP Dynamic Traffic Grooming project with support for QoS in IP over WDM Networks.

He has also participated in several research projects, such as INCT Photonics for Optical Communications, and Robust Networks Systems: Models and Tools (Big Computing Challenges call). Optical Internet Laboratory (FAPESP TIDIA Kyatera program), Nucleus of Excellence in Optical Connectivity (PRONEX), Taquara - Technology, Applications, and Quality of Service in Advanced Networks (CNPq). His participation in the Inter-Domain Peering and Provisioning Project for the Next Generation Optical Networks with the Technical University Carolo-Wilhelmina (TUBS) included a Ph.D. internship at that university.

André joined the Computer Science department at the University of Brasília (UnB) in 2011 as an assistant professor. He returned to TUBS as a visiting professor on a sabbatical between 2018 and 2019, funded by a scholarship from CNPq. In 2022, André took a three-year leave from UnB to work as a researcher on the 6G Research and Innovation Cluster (6G-RIC) German project.

André Drummond is currently an associate professor at the University of Brasília. His area of ​​activity is Computer Networks, and his research interests include optical networks, 6G, and traffic engineering.
