Scientific summary

I have worked for seven years in the area of breeding in India and have 13 years for research experience in Denmark. These gave me a good expose to know the animal breeding practices both in developed and developing world. I was involved in several EU projects and significantly contributed in successful research applications, planning and managing projects both as project leader and co-investigator. I have also research experience in gene mapping in pigs and sheep. My research has focused on developing and applying statistical genetic models to estimate population parameters, effects of single genes. Contributions include developing statistical methods to identify major genes, fine-map genomic regions affecting complex traits. I have significantly contributions are developing methods for gene mapping. My significant research success is to identify several recessive lethals in dairy cattle and significant contribution of identifying QTLs for fertility and mastitis. My research interests are as below.
• Genetic architecture for quantitative traits, understanding biology of complex traits
• Method development for genome-wide association studies (GWAS) for complex traits
• Identification of QTL for disease resistance, fertility and production traits in cattle and pigs
• Whole genome sequence variant analysis

Invited presentation at international conference

Use of full genome sequence information in fine mapping of QTL at 65th Annual Meeting of the European Federation of Animal Science (EAAP), Copenhagen, Denmark, 25-29 August 2014

Research Funding

Current projects
1. Identification and control of recessive mutations, funded by the Milk Levy Fund Denmark
2. Reduction of methane emission from dairy cows and concurrent improvement of feed efficiency obtained through host genetics and next generation sequencing of rumen microbiome, funded by Strategic Research Council, Denmark.
3. Feed utilization in Nordic cattle, funded by the Milk Levy Fund, Denmark
4. Genomics in herds, funded by VikingGenetics, Nordic Cattle Genetic Evaluation and Aarhus University.
