Working on the Google Cloud Compute Engine.

- Computer Science Research and Development to improve LogicBlox's Smart Database.- Research & development into query compilation techniques. - Research & development into using GPUs to accelerate relational queries. - Theoretical research into distributed Datalog evaluation. Work resulted in Best Paper at PODS.

Research into innovative programming models and parallel execution strategies for distributed applications.• Research is motivated by Bioinformatics use-cases from the UCD Genome Center as well as business planning applications.• Theoretical research investigating the coordination-complexity of recursive Datalog with negation. Work resulted in ICDT’2012 publication Win-Move is Coordination-Free (Sometimes); and PODS'2014 publication "Weaker Forms of Monotonicity for Declarative Networking: a More Fine-grained Answer to the CALM-conjecture."

Designed, implemented, and benchmarked grouping strategies for MapReduce’s shuffling for performance gains.• Prototyped a proof-of-concept implementation of a fuse-based solution to mounting the Google-filesystem GFS.• Worked closely with the MapReduce team at Google.

• Modified Linux Kernel to gather kernel- and user-space stack traces during context switches to analyze performance of applications; integrated stack tracing using Google’s trace gathering mechanism as well as the Linux Tool Tracekit (LTT).• Proposed visualization for system-level process performance; co-designed and implemented prototype for processing trace data to generate the proposed graphical output images.• Wrote converter for Google’s trace format to LTT format.

Designed and wrote an Oracle database application that automatically configures all of the approximately 2,000 student computers via DHCP, manages switch port configuration, security options, and VLAN configuration for the computers.• Acted as system administrator for my dormitory. Work included projection and installation of optical fiber backbone.• Maintained several Linux servers and services, including SSH, DHCP, NTP, and SAMBA.

• Extended the tool MLDesigner by proposing and developing a new domain that links it to the open source network simulatorNS2 to co-simulate network applications and protocols. Efforts led to a new revision of the MLDesigner software.• Built abstract model of the IEEE 802.11 standard for performance simulation of multiple 802.11b and 802.11g nodes.• Built a Linux-Live CD Release for the company’s main tool MLDesigner. Automated this build process for future releases.
