David N. Thomas (academic)

David Neville Thomas (born 12 October 1962) is a British scientist who is currently the Professor of Arctic Ecosystems Research at the University of Helsinki.

Education Thomas was educated at Prior Park College in Bath, UK and at Guildford College. He went on to study at the University of Liverpool and graduated with a BSc in Environmental Science in 1984. He was supervised by Drs George Russell and Julian C. Collins. In 2001, he received a Postgraduate Certificate in Teaching Higher Education at the University of Wales. There, he worked on experiments into cold tolerance of algae and oceanographic projects in the Antarctic, Arctic, and other sea areas.

Thomas returned to the UK in July 1996 to join the School of Ocean Sciences at Bangor University, where he became the Professor of Marine Biology (2006-2020), Head of School (2016-2019), and the Pro Vice-Chancellor for Research (2019-2020). During this time period, he was also a professor of Arctic Marine Biology at Aarhus University in 2013. From December 2013 to March 2019, Thomas was the director of the Welsh Sêr Cymru National Research Network for Low Carbon Energy and the Environment.

Thomas held leadership roles in two major UK research programmes for the Natural Environment Research Council (NERC). He chaired the Programme Advisory Group for the £15 million Arctic Research Programme (2010-2016). He subsequently chaired the Programme Advisory Group for the £20 million Changing Arctic Ocean Programme (2015-2021).

Concurrently, Thomas was an Academy of Finland FiDiPro (Finland Distinguished Professor Programme) from 2009 to 2013 at the Finnish Environment Institute (SYKE), where he continued as a visiting Research Professor between 2014 and 2019.

He moved to the University of Helsinki in 2020 to take up the Professorship in Arctic Ecosystems Research, where he has also been a Docent since 2010. His academic work also examines the role of dissolved organic matter, inorganic nutrients, and bacteria in ice, aquatic systems, and land-ocean transitions, and on the physiological ecology of seaweed and halophytes. In applied science, his interests encompass inorganic nutrients, phytoplankton primary production, and industrial microalgal biomass production and utilization. Beyond core research, Thomas works in science and innovation strategies, public science communication, and interdisciplinary initiatives exploring the connections between science and art.

Selected publications Thomas has authored, co-authored, and edited over 270 scholarly works, including specialist research articles and works for non-specialist audiences: Sea Ice: Its physics, chemistry, biology, geology and societal importance.
