About
I am currently working as a Postdoctoral fellow in Chair of Connected Mobility, Technical University of Munich, Germany with Prof. Dr. Jörg Ott.
I finished my Ph.D. in Collaborative Networking (CoNe) research group at Department of Computer Science, University of Helsinki, Finland in 2019. My Ph.D. was supervised by Prof. Dr. Jussi Kangasharju and focused on providing enabling protocols for edge computing.
I thoroughly enjoyed my Ph.D. experience! My journey can be summarized with this CoNe group photograph taken in the first year of my Ph.D. (dated Nov, 2016) and this photograph of my after-defense Karonkka with my opponent Prof. Dr. Abhishek Chandra (dated 8th Nov, 2019).

Research
I consider myself as a "distributed systems" guy as I have always been involved in various domains (read "avatars") of this field. "Divided we stand, united we fall" is my motto in the context of computer networking research.
Edge Computing
A broad theme of my research explores the physical deployment, specifications and effective utilization of compute resources at the network "edge".
The problem is complex primarily due to different requirements imposed by emerging applications. For example,
Internet-of-Things need data aggregation, autonomous vehicles require graphical processing,
automated industry necessitates task interoperability and AR/VR demands ultra-low network latency.
Incorporating such varying application demands to model an always available, semi-managed network of edge servers
is something I quite enjoy.

Next Generation Network Protocols
Emerging applications have significantly changed the way we interact with the underlying network.
Our old-yet-faithful protocol, TCP has started to show cracks in performance, especially in cellular and wireless environments.
I enjoy exploring and designing next-generation internet protocols which can plug-in several existing performance holes.
For this measure, I am interested in working on protocols such as Multipath TCP (MPTCP), 5G and Information Centric Network (ICN).

Blockchains and Distributed Ledgers
While edge computing has gathered quite a traction in research community, the management and operation of such large
semi to fully decentralized compute facilities in real world remains an open question. Blockchains and Distributed Ledgers
emerge as a probable technology which can allow edge providers to gain revenue, auction resources and sign service level agreements
with application providers. I am currently exploring how this technology can alleviate other open operability issues plaguing real-world
deployment of edge clouds.

Application & Service Deployment
There is a rapid shift in the make-up of cloud computing as cloud providers try to incorporate edge resources and edge accelerators
widely distributed in the region. The brunt of the complexity will be borne by existing cloud-based application as they need to depart
from traditional monolithic client-server model. Another aim of my research is to devise intelligent softwarized applications and services
which can adapt, adjust and adopt to changes in underlying compute infrastructure without sacrificing performance or quality-of-service.
