Areas of Interest

I do investigator initiated research. I created a cohort in UK called iHOPE (the incident health outcomes and psoriasis events) study – this is a prospective study of 9000 patients in which we are evaluating the GPs estimate of body surface area and how this predict future health outcomes. I have also led a series of multi-center placebo controlled trials evaluating the impact of biologics, phototherapy, and apremilast on cardiovascular biomarkers and I am running a pragmatic trial (N=1050) to evaluate the comparative effectiveness of home vs office phototherapy for plaque or guttate psoriasis.
