How can networks make trust explicit while keeping users in control of their data?
I design network architectures for systematic trust, user-controlled applications, and scalable data delivery, building and evaluating these ideas in Named Data Networking (NDN).
My dissertation, Developing a Trust Plane for Interconnected Networks, makes trust relationships an explicit part of system design through a trust plane for authentication, authorization, and auditing.

Research directions
Systematic trust
Executable trust schemas (Envelope), verifiable revocation (CertRevoke), and certificate ledgers (CLedger).
User-controlled applications
Secure collaboration and storage under user control: NDN Workspace, Repo, and Sovereign.
Scalable named-data routing
SRAN maps application prefixes at the edge, keeping core forwarding state tied to topology while supporting unicast and multicast.
