About me

I am a structural biologist who utilizes cryo-electron microscopy (cryo-EM) and X-ray crystallography to explore the complexities of life at the molecular level. My research is focused on addressing global health challenges by providing detailed mechanistic insights into critical biological processes. Beyond my research, I am dedicated to supporting the development of the next generation of scientists. Through teaching and mentorship, I aim to inspire creativity, curiosity, and a passion for discovery in future researchers, encouraging them to explore the many possibilities within structural biology.

Biography

Dr. Shanti Swaroop Srivastava is a structural biologist who specializes in cryo-electron microscopy (cryo-EM) and X-ray crystallography. He earned his Ph.D. in structural biology and biophysics from the Centre for Cellular and Molecular Biology (CCMB), Hyderabad. During his Ph.D., Dr. Srivastava elucidated the structures of diverse calcium-binding proteins using X-ray crystallography. Following that, he joined the National Cancer Institute (NCI), NIH, USA and later the University of British Columbia (UBC), Canada for his post-doctoral studies in high-resolution cryo-EM. Dr. Srivastava is enthusiastic about the potential and convenience of single-particle cryo-EM for the investigation of complex and dynamic macromolecular assemblies. His current work is focused on elucidating the dynamic structures of macromolecular complexes to address significant biological questions and improve our understanding of human health and disease. As a faculty member at IISER Berhampur, he is dedicated to both innovative research and fostering the growth of future scientists through thoughtful mentorship and teaching.


Research Projects

Molecular interactions control every aspect of cellular function. Therefore, decoding protein-protein, protein-nucleic acid, and protein-ligand interactions is critical for comprehending any cellular event. Knowing how these interactions are perturbed in various disease conditions is crucial for developing effective therapeutics and drugs. To gain such molecular insights, multiple high-resolution structures of various macromolecular complexes are required. Therefore, along with conventional molecular biology, biochemistry, and biophysical techniques, we employ cryo-electron microscopy (cryo-EM) and X-ray crystallography to determine atomic or near-atomic structures. With this, we aim to advance the structural knowledge crucial to comprehending the biophysical and biochemical aspects of protein structure and function. Current projects in the lab as as follows:

1: Elucidating the molecular design principles underlying variable substrate recruitment by PP2A holoenzymes.

2:Understanding the role of protein-protein interactions in the bacterial innate immune system using single-particle cryo-electron microscopy.

3:Structural biology of signal transmission and epigenetic gene regulation.
