Research Area: Autonomous Data Management


My research focuses on Data Management on Modern Storage Technologies.
I investigate how disaggregated memory can be efficiently utilized for in main-memory databases
so that memory demands of databases can be served by a composable data center with disaggregated memory while query performance remains efficient.


Areas of interest:

  • In-Memory Data Management
  • Modern Storage Technologies (Focus: Disaggregated Memory)
  • Memory Management
  • Index Structures
