I am interested in exploring socio-technological systems, and presently I predominantly work on topics at the intersection of computer science, social science, public policies and regulations investigating the wider societal and (cyber)security impact of technology. This includes the topics of social media & network analysis, privacy, cyber-risk analysis & management, the governance of disruptive technologies, as well as the impact and use of disruptive technologies in digital societies and in governments’ technology stacks.

This stems from my research experience spanning the topics of large-scale resilient distributed systems, information security and applications of data analytics and machine learning. Some of my distinctive and pioneering past research contributions, which have influenced new lines of research in respective research communities include: (i) decentralized online social networks for privacy and censorship resistance, (ii) novel erasure codes and associated algorithms tailor-made for distributed storage systems, e.g., self-repairing (locally repairable) erasure codes, erasure codes with elastic redundancy, codes exploiting cross-version sparsity to efficiently store multiple versions of data, quorum systems for concurrency control and consistency over coded data, and (iii) the application of machine learning and stereotyping to computational trust. I have also contributed to several well established research topics spanning security and privacy, distributed data stores, collaborative systems, complex networks, decision support applications and cryptocurrency forensics.
