Background and Research focus

Following a BSc and PhD in Chemistry (Birmingham), Roy moved to the Medical School to initiate a research programme investigating the structure and function of antibody molecules, in health and disease. Latterly, studies have elucidated the crucial role that glycosylation of the IgG antibody has on the activation of downstream effector mechanisms, both in vitro and in vivo. These findings have substantial implications for protein/glycosylation engineering in the design of recombinant antibody therapeutics and led to a number of consultancies within the biopharmaceutical industry. A current focus is mechanisms potentiating immunogenicity of therapeutic IgG molecules, including the impact of aggregates, immune complexes and allotype mismatches, between therapeutic IgG and the patient’s IgG haplotype.  Roy’s expertise is reflected in ~300 publications; in consideration of published research; he has been awarded the degree of Doctor of Science (DSc) and elected a Member of the Royal College of Physicians (MRCP) and Fellow of the Royal College of Pathologists (FRCPath).

 

Expertise

Antibody structure and function; antibody engineering; antibody therapeutics; biologics; recombinant antibodies; biosimilar and bio-better antibodies; post-translational modification; glycosylation; deglycosylation; oligosaccharide engineering; glycoforms; immunoglobulin domains; immunoglobulin free light chains; immunodiagnostics.

 

Other activities

In addition to leading his own research group, Roy holds consultancies with a number of pharmaceutical companies in relation to therapeutic antibody optimization, and antibody engineering.
