I am currently a Project Scientist in the
Center for Research on Open Source Software
at UC Santa Cruz, leading the Skyhook elastic database for the cloud project.
I also collaborate with the UC Santa Cruz Systems Research Lab
on storage systems research.
My primary research interests are in cloud databases and storage systems.
I received my PhD in June 2014 from
UC Santa Cruz Database group
and subsequently joined Hewlett Packard Enterprise Advanced R&D Lab,
Big Data Platform (Vertica database) from August 2014 to September 2016
where I worked on integrating Vertica with external analtyics engines such as
Distributed-R and Apache Spark.
At UC Santa Cruz my PhD advisor was
Neoklis Polyzotis
and my PhD thesis title is "Physical design tuning methods for emerging system architectures".
My thesis focuses on cloud and hybrid (RDBMS + Hadoop) system architectures in the new
context of database-as-a-service;
and introduces new physical design methods for data management systems in the cloud.
Abstract,
Thesis.
Previously, I received my MS from the
University of California, San
Diego in the Systems and Networking
Group.
My MS advisor was
Walt Burkhard
and my MS thesis title is "Improving disk array performance and reliability".
I received a BS in Computer Science & Engineering from the
University of South Florida.
During graduate school I spent several summers at NEC Labs working on CloudDB in the Data Management group,
at Google in the Platforms Storage group, and at
Teradata in the Virtual Storage Architecture group.
