Research competences

Since I finished my Ph.D., I have been involved in developing tools for optimisation and evaluation of breeding programs in commercial populations. The development have led to a very general simulation software, ADAM, which have been used for evaluating alternative breeding plans for dairy cattle, pigs, dogs, and rainbow trouts. I have done a lot of the programming and supervised students that also contribute to the program development. I also contribute to the design of simulation and interpretation of results.

Research area

My research have been focusing on modeling of breeding programs in order to evaluate the short- and long-term consequences of different breeding programs. I have worked primarily with breeding programs in commercial populations, but conservation of genetic diversity also has my interest. The overall focus in terms of consequences is the balance between the rate of genetic gain and the rate of inbreeding. I have been addressing issues like mating systems, female reproductive technologies, selections criteria, breeding goal, exchange of genetic material between populations, genotyping strategies, genomic breeding values, and possibility for selection in small breeds.

Research management

I had a brief stint in 2009 and 2010 as head of the research group Population Genetics and Embryology, which included approximately 20 scientific staff and 10 technical staff. During this time I had the responsibility for budgeting and personnel. I have taken courses in project management and research management.

Supervision and Teaching

Completed: 2 MSc, 2 PhD
Currently supervising: 3 PhD

I am currently teaching one half of the 10 ECTS MSc course “Animal Breeding and Genetics”. I am responsible for the part of the course on design and evaluation of breeding programs in livestock. In addition I have been teaching design of genomic breeding plans at a PhD course in Sweden in March 2010.
