About me

I am Zehao Chen, a Ph.D. student at the School of Cyber Science and Technology, Shandong University. My supervisor is Professor Lei Ju.

Research Interests:

  • Private Information Retrieval (PIR), Fully Homomorphic Encryption (FHE)
  • Computational / In-Storage / Near-Data Computing
  • Key-Value Stores (e.g., LSM-tree, blockchain storage)
  • Computational Storage Devices (CSDs), ReRAM-based Processing-in-Memory (PIM)
