I am an Assistant Professor in the Networked Systems Group of the Faculty of Electrical Engineering, Mathematics, and Computer Science (EEMCS) at the Delft University of Technology (TU Delft), Netherlands. I lead the Systems and Protocols for Edge-Enabled Internet (SPEAR) lab which focuses on research in the areas of edge computing, next-generation network protocols, Internet-wide measurements, and critical application managment/deployment. Read more about my research here.
Prior to joining Delft, I was a senior researcher in the Technical University of Munich (TUM), Germany. I received my Ph.D. from the University of Helsinki, Finland in 2019. My Ph.D. thesis has been awarded Outstanding Ph.D. Dissertation Award by the IEEE Technical Committee on Scalable Computing (TCSC). I received my Master's from IIIT Delhi, India in 2015.
I am also co-founder of Oakestra, a lightweight and efficient framework for orchestrating and managing edge computing infrastructures.

Research Overview
Curious about SPEAR lab research? Check out this interview.
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 personal 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 Networks
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 emerging cellular and wireless environments (e.g. 5G/6G, LEO satellites).
I enjoy exploring and designing next-generation networking solutions which can plug-in
several existing performance holes.
For this measure, I am interested in working on protocols such as multipath flavors of
TCP (MPTCP) and QUIC (MP-QUIC), and more.

Internet-wide Measurements
I am interested in analyzing and challenging several widespread preconceptions within
networking research community via real-world measurements. The problems I particularly
tackle in this domain range from performance analysis of transport protocols (TCP, QUIC,
etc.) in varying environments and workloads, Internet-wide scans to analyze support for
emerging protocols and widescale measurments to analyze cloud/CDN reachability.

EdgeAI & ML Model Management
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.
