As RNA biologists, we work on understanding the factory of RNA replication within the cytosol built within the first few hours of SARS-CoV-2 infection: the double membrane vesicle (DMV). Standing on the shoulders of five decades of coronavirologists, we seek to understand its regulation and biogenesis.

The Majumdar Lab combines B cell immunology with a RNA biology in new and potentially interesting ways. Read about our projects below:
mrna vaccines & Therapeutics
The past three years have opened up new frontiers in vaccine biology and delivery of mRNA/lipid nanoparticle therapeutics.
1. We seek to understand the immunological basis of the antibody immune response to current generation mRNA vaccines.
2. We develop new vaccines in mouse models in hopes of building a next generation mRNA vaccine. Here, we utilize traditional serological approaches, yeast display and deep mutational scanning, and live animal imaging.
3. We use microfluidic tools, and develop new microfluidic tools, to encapsulate RNA into lipid nanoparticles. We study these mRNA/LNPs with biophysical tools for nanocharacterization.
SARS-CoV-2 & RNA BIOLOGY
B Cell RNA Biology
RNA plays a role in how B cells maintain identity, proceed through development, and function as the cells making exquisite antibodies for the immune system. How these processes work still remails a huge open question -- we look at these questions as RNA biologists, B cell biologists, vaccinologists and biotechnologists.
We are always looking for talented students!
