Short Bio: Dr Thomas Hardjono is the CTO of Connection Science & Engineering at MIT in Cambridge, MA. USA. He is an early pioneer in the field of digital identities and trusted hardware, and instrumental in the development and broad adoption of the MIT Kerberos authentication protocol. His activities include leading innovative startups and bridging these through standardization efforts in across several industry forums, including the IETF, the IEEE, Trusted Computing Group, Confidential Computing Alliance and others. Thomas has published over 80 technical conference/journal papers, several books and over 30 patents. Current areas of interest include L1 Interoperability, Tokenized Assets, Web3 Decentralized Infrastructures, and Cyber-Resilient Protocols.
