Catherine (Kasia) Hawrylowicz is Professor of Immune Regulation in Allergic Disease and Co-Director and King's Lead for the Asthma UK Centre for Allergic Mechanisms in Asthma.

Catherine trained in immunology at the National Institute for Medical Research (Mill Hill, London) and Washington University Medical School, St Louis, Missouri, USA. Her research is investigating immunological mechanisms that ensure respiratory health, and how these change in chronic respiratory disease, including severe asthma and COPD. A major focus of the work is to understand the role of vitamin D, and intermediaries from vitamin D stimulated cells, in promoting respiratory health. More recently the work has evolved to investigate the detrimental impact of urban particulate matter constituents on immune and airway structural cell function, and the capacity of vitamin D to mitigate these effects. The work has a translational focus, incorporating studies in blood and respiratory tissue, and investigating neonatal, pediatric and adult patient cohorts.
