Dr Christian Hill
Christian is a physicist and physical chemist. His specialities are spectroscopy and the representation and communication of data in the physical sciences. Christian has developed the Quantemol database (QDB), an online sustainable database of plasma process data. Initially, QDB’s focus was on binary collisional process data presented as cross sections as a function of electron energy and Arrhenius parameter sets in terms of electron temperature. These data sets are collected into “Chemistries”, validated, self-consistent compilations of collisional processes for modelling plasma processes for a range of applications. The web software developed by Christian provides a platform for users to upload, compare and validate such data and exposes an API for its automated retrieval in a range of formats suitable for use in modelling software. Additionally, Christian has implemented XML schema expanding of the QDB data model to include a characterization of the surface (substrate) composition and structure as well as the description of the behaviour of individual adsorbed species (desorption energy, diffusion energy, etc.)
Dr James Hamilton
James completed his PhD at UCL in January 2018. During this time he worked on theoretical investigations into electron scattering with complex molecular systems from interstellar and atmospheric systems to systems for application in industrial plasma etching of silicon surfaces. He has developed and tested a new methods for calculating dissociation branching ratios for several electron scattering processes, viz. electron impact-dissociative ionisation, -neutral dissociation and -dissociative attachment, through these investigations. James implemented into Q-N software computational schemes for calculation of high energy electron-molecule scattering cross sections, extending the software capability to a desired by many customers ranging from 0 – 10,000 eV. James also provided regular customer support and undertook several advance consultancy projects which inspired and facilitated his theoretical developments.
Dr. Gwyn Evans
Gwyn has a masters degree in physics from the University of Liverpool, and completed his PhD in chemistry at University College London in 2017, specialising in chemical sensing. Gwyn has developed a beta version of the chemistry generator script. The tool allows users to input feed gases, and return reactions of interest, categorised as to whether data is available for them in QDB or not. Constituent plasma species are obtained from QDB based on the chemical composition of the feed gases. Potential reactants and products for a hypothetical reaction are combined iteratively from these species, obeying mass and charge conservation rules, to form sets of allowed chemical reactions. By significantly reducing the time necessary to assemble chemistry sets, we believe the Quantemol Plasma Chemistry Generator will help to provide quick fundamental insights into plasma chemistries.
Dr Alex Harvey
Alex completed his doctoral work at UCL and for the past few years has been at the Max Born Institute in Berlin. His research interests include electron scattering, photoionisation and recombination, with a particular emphasis on the role they play in the interaction of strong, short-pulse, laser fields with atoms and molecules. With this in mind, he has adapted and extended the UK R-matrix codes to treat oriented electron-molecule collisions, and photoionisation

Dr Derek Monahan
Derek is a computational physicist with several years experience modelling industrially relevant low temperature plasma processes. He has a BSc degree in applied physics from the University of Limerick, Ireland and a PhD in computational physics from the National Centre for Plasma Science and Technology (NCPST) based in Dublin City University, Ireland. During his time in Quantemol he focused on developing the next generation of plasma simulation tools and Quantemol-VT interface. Derek’s research interests include the low-pressure plasma global-model approximation, electronegative plasma discharges and fundamental plasma dynamics.
Dr Martin Ruskov
Martin is an Information Scientist with experience in software engineering and technology-enhanced learning. A common theme across his work is lowering access thresholds to complex knowledge domains. Martin worked on Quantemol-P in order to improve the architecture, usability and ease of use, making it faster, more intuitive and more transparent. As a result of the changes he made, the software is now easier to work with, for both developer and user, and faster in achieving results.
More information on Martin and his research interests can be found on his personal web page.
Dr Will Brigg
Will has completed his PhD with Quantemol and UCL while holding an STFC studentship. His scientific research project was focused on cross sections calculations for methane, while as part of his company internship he implemented in Quantemol-N multiple features including calculation of differential cross-sections, momentum transfer cross-sections and rotational excitation cross-sections. Will also contributed to R-matrix codes development and integrated new photoionisation cross sections calculations functionality to Quantemol-N. User friendly wizar
