After the birth of Dolly, Campbell continued to successfully replicate pigs and sheep. In 1999, he joined the University of Nottingham. Here he continued to study the cloning process. He is particularly interested in supporting the reproduction of both animals and humans. Campell has researched and developed farm animal breeding technology to develop the livestock industry and maintain food security.

Campbell also soon realized that a special ability could develop into all kinds of cells including blood, muscle and nerve cells from embryonic stem cells. Campbell lives with his two daughters, Claire and Lauren.
