Research Interests/Projects
- Wireless Sensor Networks
A key challenge in Wireless Sensor Networks (WSNs) is that of extending
the lifetime of these networks while maintaining certain coverage
goals. Existing work has studied scheduling sensors into a sleep-sense
cycle based on simple greedy criteria or using centralized optimization
techniques. We look beyond these greedy heuristics to study the problem
structure that exists between different cover sets. We propose a model
for capturing the dependencies between different cover sets, examine
ways of dealing with the exponential nature of the solution space and
discuss other improvements that can be made in picking a schedule that
maximizes the lifetime of the network. This work takes a fundamental
look into the problem structure and gives new ways to explore the
problem.
- Neuronbank
The NeuronBank project is an online reference source and informatics
tool for exploring our vast knowledge of neurons and the circuits that
they form. Broadly speaking the project comprises of NB-Central as a central interface and BranchKB's
as the individual branches that host species specific data. My
contribution has been in working on the team for the design and
development of NB-Central. NB-Central is a central entity whose
design is based on a service oriented architecture. NB-Central manages
users, collates searches and provides and uses services with the
BranchKB's. Please see the project homepage for more details.
