My Research
I have been studying
storage systems
focusing on next generation storage devices such as Flash based SSDs.
I am mainly interested in understanding and improving OS storage software stack to make better use of solid-state storage.
Thesedays, I am focusing on
Android storage sub-system
for Smart-phones.
I am also interested in
mobile virtualization.
