Teddington, London

Coordinator of the Stable Isotope Metrology to Enable Climate Action and Regulation (STELLAR) project.STELLAR is a EURAMET funded project with 14 partners (2.3 M€). Global warming is one of the greatest risks to society worldwide. To prevent stark changes to the Earth’s climate, emissions of the major contributing greenhouse gases, such as carbon dioxide and methane, must be reduced. Levels of carbon dioxide and methane in the atmosphere are at the highest they have been in the past 3 million years and this is mainly attributable to human (anthropogenic) activities. It is necessary to discriminate these anthropogenic sources from natural contributions and discern emissions from different industrial sectors, which can be done by underpinning measurements of stable isotopes of carbon dioxide and methane. This project will fill the existing traceability gap in the measurement of the isotopic composition of carbon dioxide and methane by providing a new infrastructure for delivering gaseous carbon dioxide and methane reference materials and methods This work is essential to provide governments with the data required to support inventory verification targets and enable pledges of emissions reductions to be demonstrated.

Environmental and industrial gas metrology, primarily involving research around hydrogen purity for energy applications and investigating reference standards for greenhouse gases which provide traceability for global atmospheric air quality monitoring.

Teddington

My research focused on developing graphene as a metrological standard, and metrology for graphene; characterisation of graphene for electronic devices including sensors, understanding the effect of graphene uniformity, substrate and modification on electronic properties and developing new methods to measure the properties of graphene. My current research involves the electronic characterisation of graphene from DC to THz, non-contact measurements including controlled - environment measurements and controlled environment SPM techniques. I also won funding to begin bio-sensor research for real world applications at NPL. Projects have an industrial focus, bringing electronic and SPM characterisation techniques to the graphene industry and working together with industrial partners towards develop graphene commercially.

Linkoping, Sweden

Project leader of graphene chemical sensor research. I led the graphene sensor research team and pioneered using controlled environment SKPM techniques for chemical sensor characterisation. Responsible for administration, teaching and examination of two sensor science courses at Masters level and supervision of research students.During my assistant professorship I was responsible for administration, teaching and examination of two Masters level sensor science courses entitled “Modern Sensor Systems” which is a lecture and lab based course and “Design and Fabrication of a Sensor Device” which involves lectures over one term and a project spanning over one term. Supervision of students including five Masters projects with titles “Biosensors based on MOS capacitors with an internal reference electrode”, “ZnO for O2 and NO2 gas sensors”, “New gate metals for high temperature FET NOx sensor structures”, “ Humidity stability of ZnO nanoparticle oxygen sensors” and “Selectivity of graphene sensors modified with catalytic metal films” as well as several years experience supervising labs and giving lectures and tutorials.

Supervisor; Milo Shaffer (Imperial), co-supervisors; Anita Lloyd Spetz (LiU), John Shaw (Tyco), Judith Cerda Belmonte (Imperial).Thesis title Carbon nanotubes as fire gas sensors. Partly funded by Tyco Fire and Security UK Ltd. The project involved building and testing of a reactor to grow carbon nanotubes and patterned CNT growth on electrodes by large scale CVD, characterisation of the CNTs and fabrication and gas testing of graphene sensor devices.
