- Professor Shoba Ranganathan has studied and worked in the field of bioinformatics since 1983, when the field was known as theoretical biochemistry and subsequently as biocomputing. She collaborated with pioneers in this discipline at the Institut de Biologie Physico-Chimique in Paris, funded by the Rothschild Foundation and associated to CNRS and has continued to be a leading player in bioinformatics throughout her career.
- Shoba Ranganathan was the first Chair in Bioinformatics in Australia at Macquarie University and is Adjunct Professor at the National University of Singapore (since 2004). Her research interests include genome annotation, transcriptome analysis, structural bioinformatics, immunoinformatics, genome-phenome analysis, biological networks, biodiversity informatics and cheminformatics. Shoba’s achievements include the development of graph-theoretical methods for alternative splicing analysis, a rapid and accurate docking protocol for vaccine design, pipelines for assembly and annotation of transcriptomic data, especially from helminth parasites and network approaches for large scale data mining.
- Shoba served as the first Australian Director of the International Society for Computational Biology (2003-5) and is currently the President of the Asia-Pacific Bioinformatics Network. Shoba serves on the editorial boards of several bioinformatics journals including PLoS One and BMC Bioinformatics, and contributes to the organisation and scientific program of several international bioinformatics conferences. She is a steering committee member of the International Immunomics Society and of Bioinformatics Australia. She is also a Bioinformatics and Biostatistics expert advisory panel member to the National Health & Medical Research Council, Australia since 2012.
- The Macquarie node of the ARC Centre of Excellence in Bioinformatics is headed by Shoba.
- Shoba hosted InCoB2014 in Sydney, Australia.
Curriculum vitae with publications
Shoba’s research interests are in the area of computational biology and bioinformatics. Specific examples of her recent research are outlined below.
- Alternative pre-mRNA splicing is an important mechanism for controlling gene expression in higher eukaryotes. A single gene produces several functionally diverse proteins by alternative usage of exons or introns within pre-mRNA transcripts. These gene products can be specific to tissue, developmental stage, and disease state. We have pioneered the use of graph theory for genome-wide analysis of alternative splicing in the fruitfly, chicken compared to mouse and human and more recently, the cow, contributing to the annotation of the bovine genome as well as where the cow can be used as a model for human diseases.
- Major histocompatibility complexes (MHC) play a vital role for antigen presentation and recognition by binding immunogenic peptide epitopes (p) and forming peptide-MHC (pMHC) complexes, for recognition by T cell receptors (TR), culminating in T cell activation. For efficient vaccine design and to minimize experimental T cell binding assays, advanced computational strategies for predicting strong MHC-binding epitopes with high propensity to activate T cells are required. By developing a fast accurate method for pMHC binding and analysing the physicochemical basis of TR binding to pMHC, we can accurately predicted T cell epitopes amongst high-binders for disease-implicated human MHC alleles.
Protein interaction networks:
- Biological processes are governed by generic rules embedded in the complex connectivity or networks. Systematic studies over the past few years have unveiled how these rules maintain cellular complexity by coordinating a large number of biological processes and their molecular components. Integrating data from protein-protein and metabolite-linked protein interaction networks, we have compared, contrasted and analysed the statistical properties across different subcellular compartments. Our results indicate that the metabolic network adds value to the information in the protein interaction network for the localisation process of proteins in human subcellular compartments.
- Parasitic nematodes infect humans, other animals and plants, and impose a significant public health and economic burden worldwide due to the diseases that they cause. A better understanding of parasite genomes, host-parasite relationships and the molecular biology of parasites themselves will enable the rational development of diagnostic tests and/or safe anti-parasitic compounds, following the functional annotation of parasite genomic sequences. With only a few completely sequenced nematode genomes, expressed sequence tag (EST) data-sets provide a low-cost alternative (“poor man’s genome”) to whole genome sequences and a glimpse of the transcriptome of an organism. EST data require a number of computational methods for their pre-processing, clustering, assembly and annotation to yield biologically relevant information. We have developed semi-automated bioinformatic pipelines, ESTExplorer and EST2Secretome to identify molecules involved in key biological processes or pathways that might serve as targets for new drugs or vaccines.
Biodiversity and Chem Informatics:
- Biodiversity informatics is emerging as a discipline focusing on the collection, digitisation, collation, dissemination and analysis of species-level data. We have applied biodiversity informatics tools and resources to conserve and protect customary Aboriginal medicinal plants (CMP) and their associated indigenous knowledge. In collaboration with Aboriginal communities, a web-based multidisciplinary customary medicinal knowledgebase (CMKb) was developed as a unique Australian resource. GIS and ecological niche modeling techniques were used to identify CMP species-rich areas and evaluate the cultural worth of the habitats. Further, to understand the likely impacts of climate change on the areas of highest cultural worth, predictive models were developed for current and future climate scenarios, based on spatial distributions of select CMP species.
- Bioactive compounds from natural sources are lead compounds for many therapeutic agents. Starting from the bioactive compounds in CMKb, we have carried out cheminformatics analysis of large public datasets as well as used machine learning methdos to predict novel lead molecules.
