Qualifications

Current research interests
My work focuses on various genetics and genomics related aspects of potato research in the Cell and Molecular Sciences group at the James Hutton Institute. I was actively involved in the international potato genome sequencing initiative, notably construction of the reference chromosome-scale pseudomolecules. Following this, as part of the TSB Genomes UK grant, I was actively engaged in the application of genome-wide association studies and genotyping-by-sequencing to mine diverse potato collections for identifying novel alleles affecting important agronomic and processing traits. These efforts have generated a genetically characterized potato association panel, a vast number of well-annotated SNPs and marker-trait associations.
We are exploiting these results for performing genomics-assisted breeding and generating diagnostic markers for target traits in potato. I was also actively involved in the design and development of potato whole-exome capture which we are utilizing for marker-trait analysis (e.g. using bulk-segregant analysis) on important traits including various other applications within the potato group and with external collaborating partners. Currently, I am part of the BBSRC HAPI project team studying molecular-genetic components underlying potato tuber dormancy and sprouting where my efforts also include development of transgenic tester lines for genes underlying QTLs of interest. I also have expertise in constructing Next-Generation Sequencing libraries and their bioinformatics analysis involving SNP discovery and further downstream processing. On the whole my broader focus of work is to exploit genomic technologies for furthering potato research and accelerate breeding efficiencies in potato.
Past research
I originally came to the United Kingdom on a prestigious Commonwealth Scholarship award to pursue my PhD on the development and molecular characterization of somatic embryogenesis in potato. A novel outcome of the project was the development of a prototype for rapid and efficient multiplication of potato germplasm. Prior to this in India, I was involved in the research and development aspects related to nuclear and pre-basic seed production in potato, selection and micropropagation of elite Eucalyptus trees for pulp and paper industry including the experience of running a commercial tissue culture/micropropagation facility with an annual capacity of producing over five million plants.
