Siddhartha Kumar • Postdoctoral Fellow
Simula UiB • Norway

Biography

I received my Bachelor diploma (B.Tech) in Electronics and Communication engineering in the year 2013 from Amrita Vishwavidyapeetham, India. My bachelors thesis under the supervision of Dr. Shikha Tripathi was funded by the Government of Karnataka, India (KSCST program).

While pursuing my Master of Science from Chalmers University of Technology, Sweden, I was a research intern at the department of signals and systems' communication systems group between December 2013 to February 2014. In 2015, I received my Masters of Science in Communication engineering. My masters thesis was supervised by Dr. Alexandre Graell i Amat, Dr. Iryna Andriyanova and Dr. Fredrik Brännström.

From August, 2015 to August, 2018 I was a doctoral student at the University of Bergen, and Simula UiB AS, Norway, under the supervision of Dr. Eirik Rosnes, Dr. Alexandre Graell i Amat and Dr. Øyvind Ytrehus. Currently, I am a Postdoctoral Fellow at Simula UiB AS. My research area is coding for distributed storage systems. In particular, my work includes designing repair efficient erasure correcting codes for distributed storage systems with emphasis on security, and privacy. My research interests are digital communication and channel coding theory.
