研究领域

Research in my laboratory is focussed on the study of homologous genetic recombination in mammalian cells. Procedures that we use to obtain answers to questions in these areas include techniques in recombinant DNA/molecular genetics, immunological and immunochemical techniques and techniques in somatic cell genetics.
