Post-doctoral research

 

I am currently a BBSRC research fellow funded by the Roslin Institutional Strategic Programme. A primary interest of my research lies around salmonid fish with focus on comparative and functional genomics of multiple species, while also performing applied research looking into population level variation (structural variation and SNPs) to exploit traits relevant to production and disease resistance in aquaculture. I also have a great interest in understanding the role of whole genome duplication in genome evolution and collaborate with multiple groups on this task. In addition, I am also involved in projects working on the genomics of European flat oyster (Ostrea edulis) making extensive use of the high-quality reference genome assembly we have generated for this species.

Postgraduate research

My PhD was funded by an Elphinstone Scholarship from the University of Aberdeen, with additional support from the Government of Karnataka, India. I sequenced, assembled and annotated a high-quality draft genome of the Danube salmon (Hucho hucho), a purely freshwater salmonid species, which is a sister lineage to a major clade of anadromous salmonids. The goal was to better understand the role played by whole genome duplication in the evolution of salmonid genomes and physiological systems. I used phylogenomic approaches to further our understanding of lineage-specific ohnologue resolution, revealing duplicated regions in the genome that began to diverge specifically in the common ancestor of anadromous salmonids (Gundappa et al. 2022, MBE).

Biography and previous work

I was previously awarded a 1st class MFSc degree in Fish Genetics and Breeding by the Central Institute of Fisheries Education, Mumbai, India. My master’s research focused on using in silico approaches to identify putative essential genes and therapeutic candidates in the bacterium Aeromonas hydrophila. Before this, I was awarded a 1st class BFSc degree by the College of Fisheries, Mangalore, India wherein I was exposed to various fields of Fisheries Science. I have broad interests spanning of evolutionary genetics, fish genetics, aquaculture and fish breeding.
