Maureen Callow is a leading expert in the area of biofouling (deterioration of artificial surfaces through the attachment of organisms), in particular fouling of ships’ hulls by algae. In recent years, research has focussed on understanding the processes of settlement and adhesion of algal cells to environmentally benign antifouling coatings, through collaborations with chemists and surface engineers. This research has been funded for the past 15 years by the US Office of Naval Research and more recently through two EC-funded programmes. Maureen Callow is an editor of Biofouling, the Journal of Bioadhesion and Biofilm Research.
Maureen Callow obtained a BSc and PhD in Botany from the University of Sheffield in 1967 and 1070, respectively. From 1970 – 1993, Maureen Callow was a research fellow funded by International Paints, first at the University of Leeds and from 1983 at the University of Birmingham. During this period, she was responsible for the biological evaluation of antifouling agents and surfaces for International Paint. Since 1993, her post has been funded by a number of organisations, notably the US Office of Naval Research. She was project manager (2005-2010) of the interdisciplinary 6th Framework Integrated Project ‘AMBIO’ (Advanced Nanostructured Surfaces for the Control of Biofouling) and is involved in s similar role in the Marie-Curie Initial Training Network ‘SEACOAT’ (Surface Engineering for Antifouling-Advanced Coordinated Training).
Dr Callow is known internationally in the area of biofouling and fouling control. Research interests include the control of marine biofouling, especially ship-fouling, by both biocidal and non-biocidal technologies; the development of bacterial and algal biofilms in aquatic and aerial environments; the biology of settlement, adhesion and colonisation of substrata by algal cells and spores; the measurement of strengths of attachment of algal spores and diatoms to substrata including foul-release coatings.
Dr Callow is an editor of the international journal Biofouling and has presented papers and posters at all major International Congresses in the area of Biofouling. She has authored or co-authored over 100 papers in the area of biofouling.

Algal settlement and adhesion including novel approaches to biofouling
Nanotechnology in the context of biological adhesion (collaborative interdisciplinary approaches with chemists and materials engineers).
Biofilms and bioadhesion
Biofouling of marine structures, especially by algae. The adhesion of algal spores, young plants and diatoms to surfaces and hydrodynamic evaluation of strength of attachment to novel antifouling and foul-release coatings. High throughput screening of potential antifouling and anti-adhesion compounds and novel surfaces. Much of our research is interdisciplinary and involves collaborations with European scientists in EC-funded projects and in the Office of Naval Research (USA) biofouling programme.
Research focuses on three types of marine algae that cause biofouling problems on the hulls of ships; the green seaweed Ulva, the brown seaweed Ectocarpus, and diatoms (unicellular algae).
We use these as model organisms to investigate bioadhesion processes in relation to biofouling. Work involves interdisciplinary collaborations with surface scientists, physicists, nanotechnologists and polymer scientists in the US and Europe. To study surface selection cues involved in the recruitment of our test organisms we use well-characterised surfaces that provide different physico-chemical properties e.g. wettability, charge. We are particularly interested in nano- and microtopographic modifications of surfaces. Adhesion strength of attached cells is measured hydrodynamically using calibrated flow cells and water jets. The research is generating novel insights into how the settling stages of the test organisms organisms detect and respond to surface cues and this information is then used in knowledge-driven approaches to the development of practical antifouling coatings.
