PhD, Fall 2009
Research Interests
Intelligence Storage Systems, Database Systems, Database
Performance Tuning
Projects Involved:
- New Caching Mechanism for Solid State Disk (SSD): The goal of this
project is improve the lifetime and performance of SSD using a new caching
mechanism in flash translation layer characteristics.
- Object based Storage (OSD) for DBMS: The goal of this project is to
leverage OSD for efficient database storage management.
- Database Storage Manager for SSD: The goal of this project is to design
a storage manager for database to take advantage of SSD's fast read and slow
write properties.
- Selection of Tuning Parameters of a Database Management System: The goal
of this project is to identify database performance bottleneck parameters
using design of experiments-based Plackett & Burman methodology.

Saraswat
Advisor(s):Andrew Odlyzko
(odlyzko@math.umn.edu)
Degree Plan & Expected Graduation
Date
PhD, May 2009
Research Interests
I am interested in cryptography and information security, algorithm design
and analysis, and computational complexity. I am also interested on
network security, storage security (especially long term) and protocol
security (finding weakness of an existing protocol and enhancing the
protocol).
I am currently working on long term key management for for a huge quantity
of sensitive data and large number of dynamic users.

Degree Plan & Expected Graduation
Date
PhD
Research Interests
I am interested in the design of Meta data server. For many applications we
need a distributed metadata management in the context of petabyte-scale. My
research interest is focused on designing a scalable architecture for Meta
data servers so that location tracking, access control, migration,
replication etc … can be performed efficiently in large volumes.
