Dr. Shubhada Hegde obtained her post-graduate degree in Biochemistry from Central College, Bangalore University. Subsequently, she did her PhD at the Centre for DNA Fingerprinting and Diagnostics (CDFD), Hyderabad, in Computational Systems Biology. Her thesis work largely focused on constructing and analysing genome-wide protein interaction networks. Thereafter, she worked in the Department of Microbiology and Cell Biology, Indian Institute of Science (IISc) Bangalore as a Dr. D S Kothari Postdoctoral fellow. Shubhada joined IBAB as a DST-Inspire faculty scientist, and her research areas include systems biology, network analysis and genome analysis.

Research Interest Profile
My group uses computational and systems biological approaches to understand disease mechanisms. We employ large scale genomics, transcriptomics and other high-throughput datasets and analyse them in the context of molecular interaction networks. Broadly, our research projects fall into these categories: a) Understanding long term persistence of Mycobacterium tuberculosis in the host b) Building protein and gene-regulatory networks of pathogenic organisms and c) Mining expression data in oral cancer to discover potential biomarkers for clinical diagnosis.
