My main areas of scientific interest are on genetics of aquatic organisms of relevance to aquaculture, including: sex determination and its control; genetic management and selective breeding; chromosome set manipulations and clonal lines; genomics; cytogenetics; applications of molecular markers; transgenic fish.
I have worked in a variety of countries over the last two decades, with a focus on SE and S Asia, mostly through projects, PhD students and consultancy on the genetics of carps.
I am a member of the editorial board of Aquaculture, an adviser to the International Foundation for Science, and have served as an adviser to the Commonwealth Scholarship Commission and as a board member of the International Association for Genetics in Aquaculture.
I teach on modules relating to aquaculture and aquatic genetics as part of the MSc programmes in Sustainable Aquaculture, Aquatic Veterinary Studies/Aquatic Pathobiology and Aquatic Resource Development, and to BSc students in 3rd and 4th years, doing Honours in Aquaculture or Marine Biology. This involves both face-to-face teaching and distance learning.
Current research is on genetics and genomics of tilapias, seabass, African catfish, Atlantic salmon, common carp and tilapias. This focuses on sex determination, development of isogenic lines, and genetic management and selective breeding.
