Staff Group(s)


Tristan Seecharran is a Laboratory Demonstrator within the Biosciences department at Nottingham Trent University.

His role is to assist academic staff in running the class by providing demonstrations of practical techniques and offering advice and support to students, as well as liaising with technical staff as required, to ensure that all equipment are in place and that there is sufficient availability of consumables for students to carry out practicals.

Research areas

Tristan Seecharran is a member of the Dickins Lab within the Pathogen Research Group of NTU.

He is a third year, Vice Chancellor’s Scholarship-funded, PhD student studying population genomics of important human pathogens. His research involves defining the population structure of extra-intestinal pathogenic Escherichia coli (ExPEC; the most common worldwide cause of hospital-associated and drug-resistant infections).

He is interested in studying how some sequence types (e.g., ST131, ST73 and ST95) have become principal causes of human disease.

He has also worked on Yersinia pseudotuberculosis, by combining genomic data with ecology to investigate the evolutionary events that underpin pathogenesis in this model bacterial species. For more information on Tristan’s research you can reach him on Twitter or LinkedIn.
