  • PhD Candidate

PhD Candidate in the Department of Computer Science and Technology, at the University of Cambridge.

My current research is focused on developing reliable, standardised and secure smart environments and lies at the intersection of Internet-of-Things (IoT) systems, Artificial Intelligence (AI), Cyber Security and Network Architectures in general. Over the recent years I have collaborated on the following projects:

  • Innovate UK funded Centre for Digital Built Britain (CDBB) (West Cambridge) and Adaptive City Platform: development of Digital Twin Model for two departmental buildings, deployment of LoRaWAN network across West Cambridge site (~185 sensors), development of complex event recognition and real-time data processing platforms;
  • EPSRC DADA: exploration of smart home security threats, infrastructure development for machine learning and traffic filtering techniques towards improving smarthome security; deployment of a crowdsourcing platform for secure and anonymised user traces collection for ML model trainng;
  • EPSRC Databoxlibraries/API development for system components of privacy-aware infrastructure for managing personal user application data;
  • SmartCity: Data negotiability in multi-mode communication networks (subawarded by Human Data Interaction: Legibility, Agency, Negotiability, funded by EPSRC Network Plus): exploring MUD standard for improving IoT accountability and trust as well as ML IoT models' security.
