High Speed Computer Networks: My current interests lie in Design
and Architecture of Computer Networks. Specifically, how IP, TCP and applications
behave in the face of very high capacity (giga/terrabit) networks. As the
speed and capacity of the network increases at a very fast pace, various
internet protocols may not behave optimally.
This can lead to poor performance of applications such as the web, despite
advances in the underlying physical network.
I am interested in exploring
the design changes required at the network, transmission and application
layers to ensure
they can keep up with the rapid growth in the capacity of the
network.
Network SLA Management: Another area that I am interested in
is the measurement of network performance on the internet (IP), data-link
(ATM, Frame Relay) and physical (SONET) layers. Specifically, it is a difficult
problem not only to measure performance at each of these layers, but how
to use the measurements to evaluate if a certain customer (or application)
is getting a certain level of service or not. This area is known as SLA
management. SLA stands for Service Level Agreements, which are agreements
of service level guarantees that a service provider signs with its customers.
Previously, I have also worked in the following areas.
Algebraic Algorithms: Several bottleneck Engineering and Computer
Science problemsrequire
efficient solutions to classical algebraic problems. My research work was
to design, analyze, implement and apply efficient algebraic algorithms
required for these applications.In
my doctoral thesis, we developed an efficient method to eliminate variables
from polynomial equations. This method was based on (and an improvement
of) a classical resultant method by Dixon.
Computer Vision: I worked on computer vision while at GE. Specifically
on the applications of algebraic and mathematical algorithms to photogrammetry
and object recognition.
For more details, see some projects
I have previously undertaken.
In 1996, I completed my doctorate at the
Computer
Science Department,
SUNY Albany.
My thesis developed new and efficient computer methods for solving non-linear
equations, and their applications in many areas of computer science and
engineering.
