Describe your research in a popular science way

To get good performances with feesible complexity in many systems especially those dealing with communication, two or more components have to exchange information iteratively. The choice of the components is a critical decision for such iterative systems since having the best components on each part does not guarantee good performance. Good performance comes when the components are matched. This matching comes with compromises on some aspects of the performance.

My research investigates the application of spatial coupling, a novel concepts in modern error control coding, to iterative systems ranging from communication channels with intersymbol interference to group testing (a scheme aimed at reducing the number of tests to identify objects of interest in a large population). With spatial coupling blocks of information are not processed in isolation but are linked to form a chain resulting into better and robust performance without the trade-offs involved in classical systems.  We also propose new and better approaches in the design and processing of iterative algorithms.


What made you want to pursue a PhD?

  I pursued a PhD because of the desire to dig deeper into the things. I saw this as an opportunity to push my limits and gain skills for my future pursuits.


What is the most fascinating or interesting with your thesis subject?

It is interesting to see how one concept of spatial coupling could be applied to different fields which on the surface are unrelated with interesting results.


What are your plans?

My plans are to use the skills I have gained to explore more areas of interest by continuing research in academia or solving more hands on problems in industry.
