I have a strong academic foundation in Electronics and Computer Engineering. I obtained my bachelor's degree in Electronics Engineering in 1992, followed by a Master of Science in Computer Systems in 1998, both from the Military Institute of Engineering (IME - Brazilian Army). Later in 2004, I obtained a Ph.D. in Computer Engineering from Imperial College London, UK. In 2008, I played a pivotal role as a founding staff member in establishing the Graduate Program in Defense Engineering at IME - Brazilian Army. Since 2004, I have been actively engaged as a permanent faculty member in both the Graduate Programs in Computer Systems and Defense Engineering, where I teach and supervise MSc and DSc students. In October 2023, I joined the School of Technology and Management at the Polytechnic Institute of Porto, assuming a permanent faculty position within the Department of Informatics (INF). My research interests encompass modeling, simulation, and performance analysis of computational systems, with a particular emphasis on computer networks and information systems. I am primarily dedicated to cybersecurity within computer networks, and my ongoing research endeavors also involve the application of machine learning algorithms in this field. Throughout my academic and scientific journey, I have consistently pursued an interdisciplinary approach, bridging various research domains. From delving into the intricate mechanisms of computer networks to applying high-level information systems, my aim has been to devise enhanced solutions for real-world challenges. Illustrating this approach are two distinct projects in which I served as the lead researcher (project coordinator). Firstly, the endeavor titled "Automation of Diagnosis and Fault Recovery" for the Brazilian Network for Education and Research (RNP). This project aimed to develop a system capable of monitoring all network equipment across the RNP network in Brazil, utilizing collected data to diagnose network health and automatically prevent and rectify faults. Secondly, the project "System for Acquisition and Dissemination of Epidemiological Information," supported by the Research Foundation of Rio de Janeiro State (FAPERJ). Here, the objective was to establish an information system to gather epidemiological data from various sources and disseminate processed information regarding dengue epidemics in Rio de Janeiro. The ultimate goal was to centralize efforts and facilitate efficient combat against dengue outbreaks in the state. For nearly a decade, I served as the Course Director for the Master's Program in Computer Systems at the Military Institute of Engineering in Brazil. During this time, I played a pivotal role in fostering the professional growth of numerous individuals. Some of these individuals pursued careers in academia, while others assumed prominent positions in various companies and government administrations. Throughout my tenure, I actively participated in numerous forums aimed at shaping the structure, curriculum, and organization of computer science and engineering courses within the Ministry of Education in Brazil. Additionally, as a research supervisor, I had a direct impact on the career trajectories of many researchers. To date, I have supervised the completion of 7 PhDs and have 6 ongoing, along with overseeing the completion of 37 Master's theses and currently guiding 3 ongoing ones. Furthermore, my involvement extended to serving on external examination boards for 10 PhDs and 25 Master's theses, as well as participating in admission processes for lecturers at several universities. I have significantly contributed to the scientific community through diverse means. In my capacity as a researcher affiliated with CNPq (the Ministry of Science and Technology of Brazil), I have evaluated numerous project proposals across various government funding programs. Additionally, I have served as a member of the scientific boards of several international journals.
