She has participated in over 30 clinical trials for psoriasis therapies, and is interested in comparative effectiveness studies, co-morbidities of psoriasis, and teaching investigators on clinical trial endpoints such as PASI scoring.

More recently (2001) Dr Kristina Callis-Duffin and he started the Utah Psoriasis Initiative. This project is focused on identifying clinical phenotypes and their associated findings and on identifying genes/gene-sets that associate with or drive these unique phenotypes. Currently over 1250 subjects with psoriasis have been phenotyped and enrolled in the Utah Psoriasis Initiative.

Very important to Dr Krueger and colleagues will be associations with phenotypic features, such as arthritis, nail disease, response to treatment, etc. and therewith the beginning of the discovery of the genes/gene-sets that give rise to the variable phenotypes.
