Biography
Prof. Dr. Ir. Pieter van West is a past Royal Society University Research Fellow. He is Director of the International Centre for Aquaculture Research and Development (ICARD) at the University of Aberdeen, Board member of the Sustainable Aquaculture Innovation Centre (SAIC), Fellow of the Royal Society of Edinburgh and he was President of the British Mycological Society 2017-2018) .
His current research programme focuses on oomycete biology. Several economically and environmentally important oomycetes, or watermoulds, are studied at most disciplinary levels (taxonomy, ecology, epidemiology, biochemistry and cellular and molecular biology and especially host-microbe interactions). He is particularly interested in developing novel methods to control oomycete pathogens.
The animal pathogenic oomycetes under investigation are Saprolegnia parasitica, Saprolegnia australis, Saprolegnia diclina, Aphanomyces spp. and Halioticida spp.
The plant pathogenic species include mainly Phytophthora infestans and several Pythium spp. and the algal pathogenic species include Eurychasma dicksonii, Olpidiopsis spp., Anisolpidium spp. and Maulinia spp.

Research Overview
Fundamental molecular processes in Oomycete pathogens
The group of oomycete pathogens cause destructive diseases of thousands of (commercially important) plant species and fish. These so-called watermoulds have many fungus-like characteristics, but are not true-fungi. In fact, they are closely related to kelp and diatoms.
One particular oomycete, Phytophthora infestans, the causal agent of potato late blight, generates global yield losses estimated to exceed over £3 billion annually, making it one of the most important biotic constraints to global food production. It is probably the most destructive plant pathogen in human history, as it caused tremendous human suffering in the mid 1840's due to failed potato crops in Ireland and the UK.
One of the most destructive oomycete pathogens on fish is Saprolegnia parasitica. It is endemic to all fresh water habitats around the world and is partly responsible for the decline of natural populations of salmonids and other fresh water fish. Today, losses in the salmon aquaculture business in Scotland alone are estimated at several millions of pounds annually.
Despite their economic importance, little is known about the molecular mechanisms accounting for the success of Oomycetes as plant or fish pathogens, or the fundamental molecular processes underlying their development. My research program aspires to identify molecular characteristics that are essential for the development and pathogenesis of Phytophthora, Pythium and Saprolegnia species.
Work mainly focuses on the isolation and functional characterisation of genes encoding recognition molecules and stage-specific proteins to enable
- understanding and unravelling fundamental molecular processes in Oomycetes
- the detection of molecular targets for novel control strategies, possibly directed against a variety of Oomycete pathogens.
