Diogo Rodrigues

Master's student in Distributed Systems and IT Management at Instituto Superior Técnico (IST), Lisbon.

My work focuses on building reliable distributed systems through consensus algorithms, cloud-native technologies, and secure system design.

I enjoy designing systems that remain reliable under failures, scale across distributed environments, and balance correctness with performance.

My current research explores security-aware path computation for cross-chain bridge aggregators, combining graph optimization, distributed systems, and adversarial security models to improve interoperability across blockchain networks.

Research

Security-Aware Multi-Criteria Routing for Cross-Chain Bridge Aggregation (MSc Thesis, Instituto Superior Técnico)

Modern blockchain ecosystems increasingly rely on bridge aggregators to move assets across heterogeneous networks. My research investigates how routing decisions can jointly optimize cost, latency, liquidity, and security under adversarial conditions.

The project models interoperability as a graph optimization problem and develops secure routing algorithms capable of adapting to dynamic network conditions while satisfying predefined security constraints.

Areas touched: distributed systems · graph optimization · secure routing · blockchain interoperability · adversarial security models
