Current Work
The general area for my PhD will be resource allocation in a wide area network. Namely, how can we coordinate PHY and MAC parameters, across nodes and air-interfaces, to optimize throughput in a WAN while limiting power consumption and spectrum use? The solution will involve point-to-point, cooperative, and multi-hop links, requiring distributed and efficient algorithms to configure and maintain network state.
I am currently working under the direction of Professor Behnaam Aazhang.
More generally, my interests lie in the following areas:
- Communications Theory
- Information Theory
- Network Topology and Usage
- Spectrum Allocation / Multi-user Cooperation
- Mixed Integer Optimization
- Non-convex Programming
- Complexity Theory
Previous Work
The main focus for my MS thesis was quantization. Specifically, how do the effects of an imperfect automatic-gain control impact the performance of a wireless communications link? I cast this problem as a quantization-error minimization.
I completed this thesis under the direction of Professor Behnaam Aazhang and Professor Ashu Sabharwal.
