Dr Nikki Jordan-Mahy BSc, PhD

BSc/MSci Biochemistry Course Leader and Senior Lecturer


Summary

Nikki Jordan-Mahy is the BSc/MSci Biochemistry Course Leader and Senior Lecturer at Sheffield Hallam University. She is a graduate of Royal Holloway and Bedford New College at the University of London where she received a BSc Hons degree in Physiology and Zoology. On completion of her degree she undertook her PhD at Cambridge University at the MRC Dunn Nutrition Unit. She has taught in many areas including physiology, anatomy, embryology, pathology, forensic pathology and nutrition. She is a member of the Cancer Research Group and the Musculoskeletal and Regenerative Medicine Research Group in the Biomolecular Research Centre (BMRC). Nikki supervises a number of PhD students within these two research areas.

About

Nikki has been nominated for the College and University Inspirational Teaching Award in 2013, 2014, 2015 and 2016 and won the University Award in 2014, 2015 and 2016. She was awarded the VC Inspirational Teaching Award in 2016.

She has worked in the Department of Biosciences and Chemistry for 20 years, and during this time, she has developed modules and course programs of study for undergraduates and postgraduates. She has planned key roles in the seven BSc/MSci course validation processes, in several successful accreditation from the IBMS, and more recently an Advanced Accreditation by the Society of Biology. Nikki has been a Course Leader for five degree programs, and is the current Course Leader for the BSc/MSci in biochemistry degree.

She is the Chair of the College of Health, Wellbeing and Life Sciences Biosciences Research Ethics Committee and has been a member of the University Research Ethics Committee for over 15 years. She works with both University and College members to implement and update ethical procedures and policies in the University.

She also works as an external examiner for Leeds Beckett University.

Nikki is a member of the Biomolecular Sciences Research Centre (BMRC) and part of the Cancer and Musculoskeletal and Regenerative Medicine Research groups.

Cancer Research

Her cancer research focuses on the use of polyphenols in the treatment of cancer, and their impact on standard chemotherapy treatments. This work is in collaboration with Dr. Gordon McDougall from the James Hutton Institute and other members of the BMRC and has led to the production of a number of important publications.

Other cancer research projects involve the study of metastasis formation research with Dr Nick Peak and Dr Neil Cross, and the modulation of the immune system in the treatment of cancer with Dr Rebecca Leyland.

Regenerative Medicine Research

Her regenerative medicine research focuses on the development of Novel 3D Cell culture systems for the study of gastrointestinal disease. This research is in collaboration with Prof Christine Le Maitre from the BMRC and Prof Chris Sammon from MERI. This collaboration has enabled a more materialistic approach to gastrointestinal research.

Further work into epithelial regenerative is also being undertaken in collaboration with Prof Christine Le Maitre from the BMRC and Prof Andrew Alderson from MERI and Prof Prasad Godbole at the Sheffield Children's Hospital.
