Research
My current research focuses on NoSQL and Big Data optimizations on the IBM POWER platform. I am specifically optimizing Apache Cassandra by exploiting IBM Data Engine for NoSQL (also know as the IBM CAPI Flash technology). I am also working on video analytics using Deep Learning and Apache Spark optimizations.
My background is compiler and runtime optimizations for single-threaded and multi-threaded systems. My previous work includes enhancing the performance of IBM System servers through hardware transactional memory, a new register allocation algorithm for IBM mainframe, and Java virtual machine optimizations for network processors.
I am a committer of Ruby and mainly maintains CRuby (a.k.a. MRI) on the IBM POWER platform. I am also the maintainer of lz4-java.
