Tracy was an Associated Professor in Microbiology at Nankai University, China before she came to Cambridge.  She did her PhD jointly in Nankai University and Bayer Crop Science, Belgium on investigating the diversity of Bacillus thuringiensis in China and identification of novel cry genes.  In 2003, she was awarded a Wellcome Trust International Fellowship and joined Professor David Ellar’s group at Department of Biochemistry, University of Cambridge worked on the project of “Virulence mechanisms in the pathogenesis of the Bacillus cereus group”. Tracy moved to Professor Duncan Maskell's group at the Department of Veterinary Medicine in 2006 as research associate and involved in various projects including developing Salmonella vaccines expressing Campylobacter antigens for control of C. jejuni in poultry, genome-wide analysis of Salmonella infecting livestock hosts, she was one of the leading scientists of a BBSRC LOLA project on developing vaccine and diagnostic platform of respiratory pathogens in pigs, mainly focus on Streptococcus suis. Tracy was also an external coordinator of Master Program at the Institute of Biotechnology, University of Granada, Spain since 2010. In November 2015, Tracy joined Dr. Elizabeth Murchison’s group as the lab manager/project coordinator. At her spare time, Tracy enjoys walking in the countryside and exploring the nature.
