I am a Professor of Environmental Chemistry at the University of Plymouth, where I have worked since 2001. Understanding the reactivity and characterisation of aquatic organic nitrogen (ON; both natural and xenobiotic) have been my research priorities and I have developed methods measure very low concentrations of these molecules in both water and sediments. I lead the Biogeochemistry Research Centre and my interest in nitrogen has spanned the measurement of trace gases in the Southern Ocean, the environmental fate of pharmaceuticals in water and sediments and investigating the chemistry of artificial soils made from inert waste materials.  

Research highlights include demonstrating that the uptake of ON to estuarine suspended particles is biologically- and not chemically-controlled (Tappin et al. 2010), identifying a photochemical-microbial degradation pathway for removal of N-containing benzodiazepines (e.g. valium) from aquatic systems (Tappin et al. 2014), and obtaining the first methylamine data for the Southern Ocean (Dall'Osto et al. 2017). I have supervised 9 PhD and 1 MPhil student to completion and my projects on nutrient cycling have been funded from a variety of sources,,including the NERC, the Leverhulme Trust, the Environment Agency and the EU. I am a member of the NERC Peer Review College.

I grew up by the sea in County Down, on the island of Ireland, and loved Chemistry at school; this led me to search for a university degree programme that could combine the two. I graduated in BSc (Hons) in Chemistry with Oceanography from the University of Liverpool, UK, and remained there to continue my PhD research under the supervision of Professor George Wolff (Thesis title:"The Geochemistry of the Methylamines in Recent Marine and Lacustrine Sediments") in the Environmental Organic Chemistry and Geochemistry Group. I then moved to the Marine Biological Association of the United Kingdom and worked with Professor Paul Dando on a pan-European project studying the biogeochemistry of hydrothermal, geothermal and cold seep ecosystems. In 1995, I joined Middlesex University as a Lecturer in Environmental Chemistry and renewed my interest in the biogeochemistry of organic nitrogen. At Plymouth, in addition to teaching I have acted as Admissions Tutor, Programme Manager, Senior Tutor and Employability Lead.

    Research Overview

    Nitrogen is an essential nutrient for plant growth. However, a considerable increase in the industrial production of nitrogen during the 20th century (rising from ~15 Tg* of nitrogen in 1860 to 186 Tg in 2005), and its global use in artificial fertilizers, means that it is now present at excessively high concentrations in many coastal and inland waters. This has led to a host of water quality problems, including excess plant growth, harmful algal blooms and increased water treatment costs.

    Although drinking water is a liquid, natural waters are a complex mixture of liquid water, particles and living and dead organisms. These components of water all affect how nitrogen reacts in rivers and estuaries, and how much reaches the open sea. My recent research has looked at how this mixture affects nitrogen concentrations in water, particularly the little understood organic nitrogen fraction. Human inputs are also very important and I am interested in understanding how routine activities such as dredging and sewage effluent discharge influence nitrogen concentrations, as well the predicted changed weather patterns associated with climate change.

    My research has focussed on understanding the behaviour ofvolatile, reactive chemical molecules in the environment, particularly thosecontaining nitrogen, and I have secured funding for a diverse portfolio ofresearch. Many of these compounds have been historically difficult to measureand recent method advances I have pioneered have led to collaborations on majorinternational marine research programmes, where volatile nitrogen compounds areof great interest of the oceanographic community (e.g the Antarctic CircumpolarExpedition).

    Currently funded research areas are:

    ·    Marine cycling of volatile amines and their role in climate regulation (NERC)

    ·    Can organic nitrogen support marine phytoplankton production? (EU)

    ·    Environmental behaviour of pharmaceuticals in surface water and soils (NERC, Astra Zeneca)

    ·      Biogeochemistry and sustainability of engineered soils; FABSOIL (EU)

    Through this work I hope to contribute to improved management of our aquatic ecosystems. This would include outcomes such as how the organic nitrogen transported by rivers into estuaries actually affects the ecosystem (e.g. does it stay in the estuary and remain unreactive or is it transported into coastal waters where it can stimulate algal blooms?). This data can then be used to improve environmental models that try to simulate how estuarine systems behave in order to provide a scientific understanding for the development of environmental management and policy.

    Additional information

    Away from my scientific work, I am a very keen sportsman and musician. My preferred sports are soccer (5-a-side) and golf. I have also learned to wakeboard and drive a boat recently; taking the boat out into Plymouth Sound on a sunny summer's evening for a wakeboarding session is hard to beat. I enjoy walking in the beautiful counties of Devon and Cornwall and, in between times, follow Plymouth Albion RFC. My main musical instruments are the piano and violin. My piano playing has been revived after lying dormant for many years (i.e. when I couldn't get near a piano), and I am now taking off in a jazz and blues direction, inspired by Abdullah ibrahim. I play mainly Irish music on the violin, a habit I picked up (like drinking Guinness) in the great city of Liverpool, and I am a big fan of Martin Hayes.
