Ph.D.

I completed my Ph.D. from Department of Electrical Communication Engineering (ECE), Indian Institute of Science (IISc) Bangalore in 2015, under the supervision of Prof. K.V.S. Hari. My Ph.D. was in the area of Compressed Sensing and Sparse Signal Reconstruction and I worked towards developing efficient methods for improving the estimates of the sparse signal from a highly under-determined measurement system. 


The following works came out as part of my Ph.D.
In the spirit of Reproducible Research, I also provide the codes for reproducing the results shown in my works.
