About me

I am currently working as post-doctoral researcher in The Systems Virology
Lab at Department of Laboratory Medicine. I hold Ph.D. degree in Medical
Science (specialization in systems biology applications in infectious disease
research) received from Karolinska Institutet under the supervision of Dr.
Ujjwal Neogi. My areas of interest are, systems biology, network analysis,
contextualization of networks and multi-omics analysis.
Feb 2018 - April 2023
Ph.D. in Medical Science, Karolinska Institutet, Sweden
June 2010 - July 2012
MSc in Bioinformatics, Amrita School of Biotechnology, India

Research

My work is focused on various applications of network based systems biology
methodologies to solve problems in infectious disease research. I develop
networks representing association/co-expression among various molecular
features to identify communities of coordinated response. Contextualization
of metabolic and signalling networks specific cell/tissue is another major
area of attention. I also perform other omics data analysis such as,
TMT-lablled LC-MS/MS proteomics, quantitative metabolomics and metageomics
data.
