# Kathryn Crosier

Kathryn Elizabeth Crosier ONZM (née Barber) is a New Zealand academic, a clinical haematologist, and is an emeritus professor at the University of Auckland, specialising in molecular medicine. In 2005, she was appointed an Officer of the New Zealand Order of Merit for services to medicine.

## Academic career

Crosier completed a medical degree at the University of Otago followed by a PhD titled The regulation of human haemopoiesis by cytokines at the University of Auckland in 1988. Crosier then joined the faculty of the University of Auckland, rising to full professor as Professor of Molecular Medicine and Pathology. Crosier is a clinical haematologist, and her husband Philip Crosier is also an emeritus professor of the university. Crosier is a Fellow of the Royal Australasian College of Physicians and a Fellow of the Royal College of Pathologists of Australasia. Crosier was appointed Associate Deputy Vice-Chancellor (Research) for PBRF at the university in 2010.
Crosier served as a member of the New Zealand Blood Service, being appointed in 2003 for a three year term, and subsequently reappointed in 2006 for a second term.
Crosier's research interests include medical genetics, leukaemia and stem cell development. Crosier was part of a team that announced a breakthrough in understanding of the formation of lymphatic vessels in 2019. The research, funded by the Health Research Council, the Marsden fund and the Auckland Medical Research Foundation, involved a collaboration between researchers at Auckland, the University of Münster and the University of Queensland. Researchers used fluorescent zebra fish to show that lymphatic vessels can develop through different routes, rather than from blood vessels as previously thought. The findings have relevance to the development of treatments for lymphedoema, a common condition resulting from some cancer treatments.
One of Crosier's notable doctoral students is rheumatologist Fiona McQueen.

## Honours and awards

In the 2005 New Year Honours, Crosier was appointed an Officer of the New Zealand Order of Merit, for services to medicine.

## Private life

She is married to Phil Crosier, an emeritus professor of molecular medicine and pathology at the University of Auckland.
