Biology section in IISER-Tirupati offers Interdisciplinary education in biology leading to a BS-MS degree where the student learns how Biological designs are organised, sustained and evolved in order to exhibit intricate functions at various length and time scales. Class-room teaching goes hand-in-hand with laboratory experiments that reinforce the foundational principles in Biology such that the student develops a deep appreciation towards the mechanistic basis of biological functions. We also train students in experimental research leading up to Int.PhD, PhD or post-PhD programmes. Our research programmes span diverse areas such as Cancer Biology, Genome Biology, Infectious & Parasite Biology, Plant & Animal Developmental biology, Neurobiology, Biochemistry, Ecology & Evolution.

Research Groups

B J Rao

My programme relocated to IISER-Tirupati from TIFR-Mumbai very recently. I continue my research efforts at IISER-Tirupati that are mechanism-centric and are mainly directed towards two questions of cellular-molecular biology.

  1. How do chromosomes maintain quasi-stability against a variety of cellular stresses? We probe signaling mechanisms that lead to such genome-homeostasis in mammalian cells.
  2. Chlamydomonas reinhardtii, single celled plant organism exhibits tight coordination between chloroplast and mitochondrial compartments of a cell. How is this tuned under changing cellular states? We hope to glean the dynamic signaling cross-talk between these organelles which is unique to plant world and hope to extract new Biology from it.

Molecular Microbiology Laboratory (Raju Mukherjee)

The focus of our research is circumscribed around understanding the biology of Mycobacterium species with an ultimate objective of developing strategies for successful interventions to stop the diseases (e.g. Tuberculosis) caused by these microorganism.

Plant Development & Applied Genetics Group (Eswar Rami Reddy)

Our group focuses on deciphering the molecular mechanisms and the regulatory systems that enable plants to orchestrate complex root system architecture. Further, improvement of tolerance in crop plants to abiotic stresses (drought, salt and heavy metal) by improving root traits.

Molecular Oncology and Cell Signalling (Pakala Suresh Babu)

Our group works on understanding the molecular mechanisms of coregulators in signal transduction, Gene regulation, inflammation, Cancer progression and Cancer metastasis. Our research interests also include developing transgenic and knock out mouse models for studying the role of coregulator signalling in cancer and inflammatory disorders.

Cellular and Molecular Parasitology (Suchi Goel)

Our research focuses on pathogenesis of severe malaria parasite where adhesion of parasites in the microvasculature leads to activation of stress signalling pathways in human host.

Neuroscience Lab (Vasudharani Devanathan)

Our group is focused on the following areas of research:
Cell adhesion molecules (CAMs) in regulating neurogenesis, neurite outgrowth and degeneration; specific interactions among CAMs and their downstream signalling mechanisms.
Molecular mechanisms of neuronal dysfunction in diabetic retinopathy.
G-protein signalling in platelets and neutrophils.

Cellular and Vascular Biology Lab (Sanjay Kumar)

Our lab research focuses on signaling mechanisms that define the complex responses to TGF-β in the mammalian system.  We also study the role of mitochondrial proteins in normal cellular functions and human diseases. 

 

Ash Lab (Ashwani Sharma)

Ash Lab works in the area of nucleic acid aptamers, which are single stranded DNA or RNA oligonucleotides having high affinity and specificity to their target. Aptamer binding to its target is utilized in designing new biosensing platforms for disease detection and diagnostics. In addition, the lab also focuses on construction of DNA/RNA based nanoparticles decorated with aptamers and oligotherapeutics such as siRNA for the targeted drug delivery to different cancers.
