Guilherme Rosas Borges finished his Master's Degree in Computer Science and Engineering in 2018, at FCT NOVA in Caparica, Portugal. His thesis, entitled "Practical Isolated Searchable Encryption in a Trusted Computing Environment", was advised by professors Bernardo Ferreira and Henrique Domingos, having received a classification of 19 out of 20. He started his research activities in 2016 as a BSc student at the NOVA LINCS Research Centre, for which he was selected for a scholarship. As a Master's student, he participated in the LightKone European project (particularly Work Package 5), as well as the COSMOS Portuguese project, having received research scholarships from both projects. He was a teaching assistant at FCT NOVA in 2017 and 2019, teaching the "Software Development Methods" and "Informatics for Science and Engineering" courses for third- and first-year undergraduate students, respectively. He published a paper at INForum'18, entitled "Pesquisa Booleana Cifrada usando Hardware Confiável". He is also a co-author of a paper at the 38th IEEE Symposium on Reliable Distributed Systems (2019), entitled "BISEN: Efficient Boolean Searchable Symmetric Encryption with Verifiability and Minimal Leakage", as well as a journal article at the IEEE Transactions on Dependable and Secure Computing (2022), entitled "Boolean Searchable Symmetric Encryption with Filters on Trusted Hardware". He was responsible for the implementation and evaluation of all the protocols devised in those papers. He has presented the results of his research work at the M12 and M24 LightKone meetings, in 2018 and 2019, respectively. As a researcher at NOVA LINCS, Guilherme participated in several activities both in the research centre and the computer science department, having been on the team that developed FCT NOVA CodingFest, a platform to teach programming to primary and secondary school students. He was a volunteer at several department activities, both as a co-organiser and as a student volunteer. His poster, titled "Practical Isolated Searchable Encryption in a Trusted Computing Environment", detailing his research activity, was exhibited during the centre's evaluation process by Fundação para a Ciência e Tecnologia in 2019. Outside of academia, he worked as a freelance software developer, having developed projects such as "clica.ai", a URL shortener for the Portuguese-speaking market, and "Destaques do Passado", a tool to visualise historical news from "Arquivo.pt", the Portuguese web archive. He participated in the Google Summer of Code project in 2019, developing a high-interaction honeypot ("Cowrie") for the Honeynet project using software virtualisation. He is currently (2023/2024) a secondary school teacher in Porto, Portugal. Teaching different subjects related to computer science, he also conducted a series of workshops on Internet security and good practices for juvenile inmates in Porto. His research interests are centred on network and distributed systems security, particularly Trusted Hardware in Cloud settings and anonymisation networks.
