Present Research Interest
Our group primarily focuses on the host-pathogen interactions in human viral infections with particular focus on flaviviruses (Ex: Dengue virus) and respiratory viruses (Ex: Respiratory Syncytial Virus). Our primary objective is to generate basic knowledge in virus-host interactions that can be harnessed for vaccine and drug development. Focus areas include:

Recent outbreaks of several pathogenic viruses like Ebola, Dengue , Zika , and now SARS-CoV-2 make virology research exciting. There is conceivability of new viruses emerging that can infect humans, and demanding regular research about these viruses to develop treatment methodologies. I am contributing to establishing platform technologies to support prophylactic and therapeutic strategies for Dengue-Discovery to proof-of-concept.
I have always been a very creative person and find it relaxing to indulge in craft activities.
Shivam SinghPh.D. Student (April 2021 – present)
M.Sc. Biotechnology (2019) from Central University of Rajasthan
Email: shivamsingh@thsti.res.in
I was always fascinated with viral diseases and to think about the ways we could tackle them. The SARS-CoV-2 pandemic has highlighted the multipronged approach one needs to take to do so. With the urge to learn more in this field, I joined CCV lab in April 2021. Prior to this, I worked at the All India Institute of Medical Sciences (AIIMS), New Delhi as a Junior research fellow. Currently, I am working on Respiratory Syncytial virus.
My hobbies are playing badminton, volleyball, and travelling.

M.Sc. in Molecular Medical Microbiology (2020) from Indian Institute of Technology, Kharagpur
Email: rohitsingh@thsti.res.in
I began my journey in the field of biological sciences with an internship in a Forensic biology laboratory wherein I saw science in action and its far-reaching effects on society. During my undergraduate and postgraduate coursework, I developed a keen interest in infectious diseases, immunology, and epidemiology, which encouraged me to join the CCV lab. When I am not in the lab, I like to read novels, cook, dance, travel, and watch movies.
Ph.D. Student – 2020 - Present
M.Sc. in Biotechnology from Visva-Bharati, West Bengal (India)
B.Sc. in Life Science from University of Delhi, Delhi (India)
Viruses are the simplest non-living creatures in the world which are able to infect diverse groups of living organisms. My passion is to explore the simplicity of virus as an organism and its complex interactions with the host. Currently, I am trying to understand the role of immune evasion strategies of dengue virus.
Apart from academia, I love to play cricket and listening music.
