Research

Old research: string matching and data compression.

My first chosen path of research in my current position has been to exploit the knowledge I gained during my years in the software development, as a starting point for academic research. This research belongs in the intersection between database systems, algorithms & data structures, and logic. In particular, I have worked on a light-weight scheme for cuncurrency control in cache management, designed to work well with typical access pattern in internet sercices, be simple to use via a minimal API, and easy to integrate with other components. Another area to explore is a second-order logic view of database systems, and in particular how this view can help efficient implementation of database platforms with complex non-standard organization.

Currently, my research interests have moved back towards data compression. I am exploring the topic of compressing sets of items, as opposed to the sequences that compression algorithms conventionally assume as input.
