 My research interests focus on Computer Architecture and Operating Systems, especially on [Virtual Memory](https://en.wikipedia.org/wiki/Virtual_memory). Virtual memory is a nice [middle layer](https://en.wikipedia.org/wiki/Indirection) providing good programmability and performance, but now needs to catch up with new Heterogenous Memory Systems.

I design efficient [hardware](https://normal.zone/publications/2017-06-24-ISCA-2017) and [software](https://lwn.net/Articles/728154/) to enable the full potential of new heterogeneous memory systems by accelerating data migration between different memory nodes in a system.
