Dr. Mamta Chawla-Sarkar joined ICMR-NICED, Kolkata in January 2006 as Scientist C. She gained her Master's in Zoology in 1992 from Calcutta University and acquired the degree of Ph.D from Bose Institute-Jadavpur University, Kolkata in 1999. She did her Post-doctoral research work as Research Associate for six years in the Center for drug discovery & development, Taussig Cancer Center, Cleveland Clinic Foundation, Cleveland. Her research focus was analysis of the genes involved in anti-canter effects of Interferons and the mechanisms underlying IFN resistance in tumors of different histopathologies. Dr Chawla-Sarkar was promoted as Scientist F in 2019.
After joining ICMR-NICED, Dr. Chawla-Sarkar initiated studies both basic and Public health aspects of RNA viruses which cause significant morbidity and mortality worldwide. As part of a National Diarrhoeal disease research institute, her focus is on enteric viruses. An estimated 200,000 deaths are attributable to rotavirus each year, over 20% of which are estimated to occur in India. Inspite of their great medical importance, information about the molecular mechanism by which these subvert their hosts' cellular immune response or the involvement of host proteins during infection was not well defined. Her studies using OMICS platforms (microarray and proteomics) have led for first time to the identification of a number of cellular genes which positively aid virus replication. The host proteins are either upregulated, downregulated or modified post translationally by the viral proteins. Modulation of a subset of cellular genes by using agonists or antogonists have shown potent anti-viral effects with minimum cytotoxic effects on the cells suggesting that Host-targeted antivirals can be exploited as potential antiviral therapeutics. She has extended her experience on Rotavirus to SARS-CoV2 in 2021 and is currently focusing on role of lncRNA's in SARS-CoV2 infection and pathogenesis.
Besides this, she has made vital contributions towards viral disease surveillance. Her lab was the nodal lab for Influenza virus testing in the eastern India. During the Influenza A/H1N1/2009 pandemic and H1N1outbreaks since 2009, her lab provided the full laboratory diagnostic service to the WB State health department. In addition, her lab also served as east-zone referral lab for the National Rotavirus Surveillance Network. During the COVID -19 pandemic, Dr Chawla Sarkar was part of the team which led to providing lab diagnosis, kit validation, full genome sequencing and phylogenetic analysis of SARS Cov2 strains.
Human Resource development and capacity building has also been
given importance- As of 2022, 15 students have been awarded
Ph.D.; six students are working for their Ph.D. She has provided
hand on training to the MSc students, technicians and
microbiologists for handling of clinical samples, ELISA/ PCR
based diagnosis of viruses.
Dr. Chawla- Sarkar has published > 95 research papers in peer
reviewed journals. She received NASI fellowship (FNASc) in 2013,
DBT's Women Scientist (Young) award (2013), ICMR's Kanishka
Oration award (2017), Fellowship of WB Academy of Science and
Technology (2018), Fellowship of INSA (FNA) in 2020 for her
scientific contributions in field of viral diseases.

Dr. Mamta Chawla-Sarkar has more than 20 years of research experience in the field of biomedical research. During her post-doctoral training (1999-2005) at Cleveland Clinic Foundation, USA, she worked on understanding the role of IFN as anti-cancer therapeutics and mechanisms which underlie IFN resistance in subset of patients. In 2006, she joined as Scientist C in ICMR-NICED and started studying both basic and public health aspects of Rotavirus (Enteric) and Influenza A virus (Respiratory), both of which cause significant morbidity worldwide. Her research group focus involved strain surveillance, host-virus interaction and identifying cellular proteins/miRNAs involved in viral pathogenesis for developing potential antiviral targets. She coordinated ICMRs National Rotavirus Surveillance Network and Influenza Surveillance Network in the Eastern zone. Dr. Chawla-Sarkars lab was responsible for providing laboratory support in West Bengal during A/H1N1 pandemic in 2009 and during the SARS-CoV2 pandemic in 2020-21. In addition, her team performed sequence analysis and phylogenetic analysis of the SARS-CoV2 strainsand performed molecular kit validations. She has been actively involved in institutional activities related to Biosafety, promotion of Rajbhasha and preparing technical specifications for equipment purchase.
Research Interests of Dr. Chawla Sarkar and her team involve studies on both basic and public health aspects of infectious pathogens. Following broad areas of research are:
