Valerio obtained his PhD from University College London on laboratory studies of the kinetics of ozone-depleting halogen oxide radical reactions. He then worked at the National Physical Laboratory on the detection of volatile organic compounds and reactive gaseous species using a variety of techniques. Following a post-doctoral position at the University of Cambridge in which he explored tropospheric oxidation pathways in global atmospheric models, he moved to his current position in Cranfield to work on the development of low-cost sensors for long-term monitoring of atmospherically important species. 

Laura Alcock BSc. (Hons)

Laura Alcock is a Development Chemist at Edwards Ltd. The site where she is employed manufactures Exhaust Management, or Abatement, Systems for the safe destruction and removal of harmful process gases involved in the manufacture of semiconductors, solar panels, flat panel displays, LEDs, etc., to prevent their introduction into the environment. She is responsible for developing the existing products and their specific functions, in order to improve their efficiency, whilst minimising by-product emissions.

Laura studied her BSc. (Hons.) in Forensic Science, at Liverpool John Moores University and has a varied work experience which  opened her eyes to the extent to which people consider their surroundings as disposable. Her work now allows her the opportunity to correct this consideration and to make a real contribution to the protection of our global environment. Laura is currently looking into study for a PhD, with a particular interest and focus in environmental chemistry and energy processes. Laura joined the committee in 2018.

Dr Rowena Fletcher-Wood AMRSC

Distinguished Guest Lecture Convener & Assistant Editor ECG Bulletin

Rowena Fletcher-Wood is a science communicator for Science Oxford and a science writer. She completed her doctoral research in environmental materials chemistry at the University of Birmingham on remediation of chromate species in waste water using redox-active molecular sieves and previously studied at Somerville College, Oxford. Her interests lie in science communication and outreach.

Dr Caroline Gauchotte-Lindsay

Caroline is a lecturer in Environmental Engineering at the University of Glasgow. Caroline holds Masters degrees in Analytical Chemistry (EPSCI-Paris) and Forensic Science (University of Strathclyde) and a PhD in Environmental Engineering (Queen’s University, Belfast) and works at the boundary between engineering and science to tackle some of the most pressing environmental challenges such as pollution and water scarcity. Her research employs states of the art analytical and spectroscopic approaches to track and remediate contaminants, e.g. persistent organic pollutants, personal care products and micro plastics, in the natural environment and in engineered systems. world” issues and have developed solid partnerships with industry and policy makers. From early in her career, she has been committed to research that is strongly anchored in real-funding and support from companies and governmental bodies. Caroline is also an active player in issues around diversity and inclusion in STEM, she is co-project director on the VisNET Inclusion Matters project and a member of the TIGERs in STEMM. Caroline joined the committee in 2018.

Professor Steve Leharne CChem FRSC

Professor Steve Leharne CChem FRSC is Professor (emeritus) of Environmental Chemistry at the University of Greenwich. His major scientific and research interests have been focussed, over the past twenty years, upon the transport and fate of denser than water non-aqueous phase liquids in soils and aquifer formations. Typical examples of these organic liquids, commonly referred to as DNAPLs, include chlorinated hydrocarbon solvents and coal tar. The second major research theme arising from this primary focus has been on the remedial challenges arising from the water quality degradation that arises from DNAPL presence in groundwater. In particular we have examined the use of surfactants and more recently colloidal particles to remove entrapped DNAPL droplets from water wetting porous media. Leharne is the co-author of two practitioner focussed Handbooks dealing with DNAPL and LNAPL fate in UK aquifers published respectively by the Environment Agency and CL:AIRE (Contaminated Land: Applications in Real Environments.

Dr Laura Newsome MRSC

Website editor

Laura is a lecturer in Applied Geomicrobiology at Camborne School of Mines, University of Exeter. Her research interests cover how the activity of microorganisms influences geological and geochemical processes and vice versa, particularly how microbes affect the fate and transport of contaminants and metals in the natural environment. Laura gained her PhD at the University of Manchester and prior to this she worked at the Environment Agency and as a contaminated land consultant.  Laura joined the committee in 2017.

Dr David Owen CChem MRSC

Dr David Owen is the retired Founder and Managing Director of Treatchem Ltd, an SME company specialising in custom designed  process water and waste water management programmes . The company exists to help industrial water users comply with environmental regulations by the supply of consultancy, chemicals and temporary plant where required. David is a serial entrepreneur in the field of environmental speciality chemical applications.

Dr Tomás Sherwen

Co-opted member
Dr Tomás Sherwen is a research scientist for the National Centre for Atmospheric Science (NCAS) at the University of York where he has a focus on numerical modelling of the chemistry of the atmosphere.

His PhD focused on developing the atmospheric chemistry scheme in the global open-source GEOS-Chem model to explore the concentrations and the effects of halogen chemistry in the preindustrial & present day. Since then he has worked at both global and regional scales and uses novel machine-learning techniques. He works on a range of science questions from Criegee intermediates to sulfur-halogen atmospheric cycles to sea-surface concentrations. Tomás joined the committee in 2019.

Clare gained her PhD at Warwick University on the preparation of telechelic methacrylates using macromers as chain transfer agents.  She then worked in the contact lens industry before moving to a position with an irradiation company.

Professor Dominik Weiss FRSC

Dominik is a Professor in Environmental Geochemistry and has extensive experience in conducting research in low temperature geochemistry. His work tries to explain what controls trace element cycling in the environment from molecular to global scales.  A special focus is on understanding the chemistry at surfaces and in solutions as well as on global biogeochemical cycles. Key contributions to date have been pioneering the application of non-traditional stable isotopes in environmental science, improving our understanding of Zn efficiency mechanisms in rice, in developing a qualitative and quantitative understanding of human impact on atmospheric metal cycles and in establishing peat core archives as terrestrial archive to study changes in global dust cycles. His group uses a combination of field, laboratory and theoretical experiments to test underlying hypothesis or to improve the understanding of processes and mechanisms.
