Donald’s main area of research is focused on investigating the cellular and molecular interactions involved in T cell development and in particularly understanding the processes that are involved in age-associated thymic involution and immunosenescence.

He has used antibody phage display technology to identify cell surface structures expressed on thymic epithelium that are involved in stromal cell-thymocyte interaction; which is still an ongoing project. Furthermore, in a collaborative project he has used this technology to identify cell surface structures on tumours. Cross-talk between the immune, endocrine and nervous systems involve common neuroendocrine circuits and Dr Palmer’s work has demonstrated the expression of several neuropeptides and their receptors in the thymus of different species and showed that these peptides can directly modulate thymocyte differentiation.

These studies led Dr Palmer to pursue an interest in understanding how ageing affected the immune system, in particular the mechanisms involved in age-related thymic atrophy. He’s group have been investigating the architectural changes in the ageing thymus, and made the novel finding of the presence of senescent cells in the thymus of older animals (in collaboration with Professor Thomas von Zglinicki, Institute of  Ageing and Health, University of Newcastle). In addition to these observations, examination of thymocytes also revealed age-related alterations in phenotype and function. Dr Palmer has extended his interest on the affect of ageing on other components of the immune system and is examining Natural Killer cell function in the elderly (in collaboration with Prof Arne Akbar and Dr Sian Henson, UCL).

He also has an interest in comparative immunology and is currently examining the thymic architecture and function in different species.

Donald teaches on the BSc in Bioveterinary Sciences, BVetMed  and Gateway to BVetMed programmes.

He is currently First Year Leader for BSc/MSci Biological Sciences and Bioveterinary Sciences Programmes, Deputy Senior Tutor (Camden Campus) and Deputy Strand Leader for Lymphoreticular & Haemopoietic’ Strand (2nd Yr BVetMed).

Primarily, he teaches Immunology and Cellular Biology on these programmes.

Additionally, Donald teaches on the MSc in Immunology at Imperial College, BSc in Biological Sciences at UEL, Pathology Module in the Natural Science Tripos (Year 3) at University of Cambridge and the Infection & Immunity option in the third year undergraduate medical course at Oxford University.

He is a Registered Practitioner of The Higher Education Academy, having successfully completed a Postgraduate College Certificate in Academic Practice at King’s College London, and is currently the Higher Education Academy Biosciences Representative for the RVC.

Donald was previously External Examiner for BSc Biological Sciences at University of Bedfordshire (2012-2017) and currently an External Examiner for BSc Biomedical Science (Y1 and Y2) at St George's University of London (2016-2020) and Part IB Pathology course for Y2 undergraduate students at Cambridge University (2019-2021).

Donald is  passionate about increasing scientific awareness amongst the general public and fellow scientist, and also to encourage young people to consider a career in science by regularly contributing to public engagement activities; speaking at schools, colleges, community events and scientific festivals.  He has often provided comments in the area of immunology to various media outlets. Donald has  developed and teaches on a Biology Masterclass for year 12/13 pupils which consist of ‘a day at university’ involving lectures, a practical together with guidance on university application; as part of the college’s widening participation activity. Donald is a mentor and role model for various organisations and Chair of Govenors of a school in North London .
