Research
I am a final year PhD student working under the guidance of Andy Tanenbaum on
all things storage related. In collaboration
with David van Moolenbroek I
designed and implemented Loris, a file-based
storage stack that solves various flexibility, reliability, and heterogeneity
problems that plague even state-of-the-art file systems by design.
In the summer of 2012, i interned at Microsoft Research, Cambridge under the
supervision of Ant
Rowstron. There, i worked on debunking traditional myths and
rule of thumbs regarding scaling up data analytics workloads.
