Biography

Professional biography

My research interests include sustainable chemistry, recycling of wastes, heritage science, materials chemistry,  chemical education, biological inorganic chemistry, catalysis, and environmental chemistry.

My PhD concerned ‘Bioinorganic chemistry mimicking copper metalloenzymes’ with Professor David Fenton at the University of Sheffield and was sponsored by BP Chemicals. This developed dicopper complexes of macrocylic Schiff base ligands.

I then worked at the University of Kansas as a postdoctoral fellow developing ‘Metal catalysts for bleach activation’ with Professor Daryle Busch and the Proctor & Gamble Company which led to several patents and publications. 

I returned to the UK in 1998, working at the University of Exeter  as a postdoctoral fellow studying ‘Metal containing liquid crystals’ with Professor Duncan Bruce.  In 2000 I continued at the University of Exeter as a postdoctoral fellow developing ‘Electrochemical sensors for biological molecules’ with Dr Jim Tucker.

In 2001 I was appointed at the University of Nottingham as a temporary lecturer and subsequently teaching fellow in Inorganic Chemistry.

In 2009 I moved to Cranfield University as a lecturer in Environmental and Waste Chemistry. 

I joined the Open University in November 2011 as a Teaching Fellow in Chemistry and an Associate Lecturer on the level 3 Metals and Life course.

In 2014 I was promoted to be a Lecturer in Chemistry and Senior Lecturer in 2019.

Research interests

Applied Research

I have a long standing interest in applying chemistry to real world challenges.  Current and recent projects include;-

1) Cleaning costumes, vintage rugs and carpets (originally funded by HEIF in colaboration with the Victoria & Albert Museum) and now this is an AHRC PhD project with the V&A.

2) Conserving and educating the public about bioplastic items in museum collections with the Museum of Design in Plastics (MoDiP) and this is an AHRC PhD project.

3) Crop by-product processing into nanomaterials incorporating bioactives for targeted release and shelf-life extension (collaboration with University of Newcastle, Fera, Biopower Technologies Ltd, Marks & Spencer and New Food Innovations funded by FoodWasteNet). A PhD student continues this research area staring in Oct. 2020.

4) Development of more environmentally-friendly road markings, Knowledge Transfer Partnership with WJ Products Ltd and the Open University.  

5) Recycling waste plastics either by depolymerisation to their monomers (e.g. mixtures of polyethylene terephthalate and polylactic acid) or decolourising waste plastic film (e.g. polyethylene or polystyrene) (funded by CIWM).

6) Upcycling of food waste into higher value proteins or peptides using (a) polymer supported transition metal catalysts and (b) chitosan supported enzymes. (funded by CIWM, IBCarb, Nuffield Foundation and Yessenov Foundation).

7) Analysing precious and strategically important metals in waste materials (e.g. Waste electronic and electrical equipment, WEEE, ash from incineration and leachate) (funded by CIWM)..

8) The application of catalysis to the conversion of biomass, in particular the oxidation of starch, cellulose and lignin (funded by the Nuffield Foundation).

9) Recycling carpets in the removal of pollution (e.g. phosphate or metals) from water (funded by CIWM).

10) Modelling micorplastics within the Environment with C. Elegans nemaotdes.

We gratefully acknowledge AHRC, OOC, EPSRC, DEFRA, the Chartered Institute of Wastes Management (CIWM), the RSC, FoodWasteNet, IBCarb Network, the British Council, Geotech, Higher Education Innovation Fund (HEIF) and the Nuffield Foundation for supporting this work in recent years.

Also I acted as an Associate Editor for the Journal of Chemistry (2014-2017).

Educational Research

I am part of teams developing home experiments on sustainability with Smart phones and remote OPENScience lab undergraduate experiments in particular using remote FTIR, an autotitrator and flow chemistry.

I have been researching best practise in student teaching and learning using synchronous and asynchronous online media.  For instance in collaboration with Drs Crabb, Williams and Janes we have an eSTeEM funded project entitled Graduate skills in chemistry: online delivery, assessment and tracking.

I am also interested in improving the experience of international students in online learning and developing problem based learning for chemistry students. Consequently I led a HEA funded project on context based learning activities to better engage international students in distance learning.

Concurrently, I supervised undergraduate summer project students Ellie Atkinson, Abi Barbour, Joe Beebee, Millie Dean, Charlotte Hancox, Kirsten Hawkins, Sophie Patrick and Alex Simmons. Also French visiting students Marine Klehenz, Alexandre Piton and Clemence Sayer.

 I am a comittee member of the RSC MidAnglia Local Section and the RSC Eastern Region Steering Group. Also I am a STEM ambassador and have led several outreach activities on Plastics and their recycling for ChemistryInAction and Education in Action as well as RSC Top of the Bench.
