Brief Bio

I am an assistant Professor in the computer science department at Purdue university. Before joining Purdue in 2015, I was a junior faculty member and an independent research group leader at Saarland University , Germany. I completed my postdoctoral fellowship at Max Planck Institute for Software Systems (MPI-SWS), Germany in 2012, and received my PhD from the University of Waterloo, Canada in 2010.

Research Interests

I design, implement, and analyze privacy and transparency enhancing technologies. My research integrates cryptography, distributed computing, and data-driven analysis to solve security/privacy problems in decentralized environments.

Prominent Research Thrusts

  • Cryptocurrencies and Blockchains [WWW '18] [NDSS '18 '17 '15] [CCS '17 '15] [PETS '17 '16] [ESORICS '14]
    • analyzing and improving privacy and security of cryptocurrencies (e.g., Bitcoin), IOU credit networks (e.g., Ripple), and consortium/permissioned blockchain solutions (e.g., Hyperledger)
    • developing innovative cryptography-aided (smart) contracts for non-traditional real-world applications
    • designing novel distributed ledger (or blockchain) architectures for (physical/digital) supply-chains and IoT

  • Anonymous (Meta-data Hiding) Communication [Oakland '18] [NDSS '17] [ACNS '17 '15 '14] [ESORICS '16] [CCS '14] [CSF '13 '12] [WPES '12] [TISSec '10] [FC '10] [PETS '07]
    • understanding the fundamental communication lower bounds for anonymous communications
    • developing cryptographic primitives to enhance privacy, scalability, efficiency, and accountability of anonymous communication and anonymous storage protocols
    • building a framework (AnoA) for defining, analyzing, and quantifying anonymity properties for ACNs
    • developing a light-weight monitor (MATor) to assess the anonymity of Tor and other ACNs in real time

  • Longitudinal Privacy and Right to Delete/Conceal/Forget [IC '17] [SOUPS' 16]
    • analyzing users' deletion habits on the online platform, right to be forgotten, and the associated Streisand effect
    • proposing effective counter-measures to protect those deletions from the Cyberstalkers

Other Projects

  • Privacy-Preserving Web Analytics [ACSAC '14] [Oakland '12]
  • Accountability and Transparency [TDSC '16] [COSN '15]
  • Multi-party Computation and Threshold Cryptography [PODC '14 '12] [CT-RSA '13] [ASIACRYPT '11 '10] [SCN '10] [ICDCS '09]
  • P2P/DHT Systems Privacy and Security [ToN '13] [ASIACCS '12] [ICDCS '10]
