Dr Jason Hallett received his PhD in Chemical Engineering from the Georgia Institute of Technology. He joined Imperial College, first with a Marshall-Sherfield Postdoctoral Fellowship in Sustainable Chemistry and in 2014 was appointed a Senior Lecturer in the Department of Chemical Engineering, before promotion to Reader in Sustainable Chemical technology in 2016. He has authored over 60 articles and holds 4 patents. His current research interests involve the solvation behaviour of ionic liquids and the use of ionic liquids in the production of lignocellulosic biofuels and sustainable chemical feedstocks. This research is supported by both the EPSRC and industry.
Dr Hallett currently serves as Director of the Imperial Network of Excellence in Industrial Biotechnology and as theme leader for Biorenewables and Biofuels research in the Manufacturing Futures Lab.
He is also co-founder of Chyrsalix Technologies, a spin-out company based on the group's ionic liquid biorefinery research.
PhD studentships: The Department of Chemical Engineering is currently accepting applications from outstanding students for our Departmental PhD Studentships (http://www.imperial.ac.uk/engineering/departments/chemical-engineering/courses/postgraduate/phd/scholarships/).
These are fully funded 42-month positions with a host academic. If you are interested in applying for a scholarship hosted in my lab, please contact me (firstname.lastname@example.org)
Funded opportunity (UK students):
This is a fully funded Industrial CASE project with Dr Jason Hallett (Department of Chemical Engineering, Imperial College, email@example.com, http://www.imperial.ac.uk/people/j.hallett), Prof Paul Fennell and Prof Geoff Kelsall. The project will focus on the use of ionic liquids for in the fuel industry, with a focus on purification using extraction and electrodeposition to remove trace impurities from transport fuels.
The project will include a selection of topics from the following areas:
• Economic design of ILs/mixtures to target specific metals of interest including novel ILs
• Reaction condition studies for IL mixing – Temperature, Viscosity, interfacial tensions and densities
• Electrochemical visibility of metals in certain ILs
• Design of processes for mixing, phase separation and filtration on a large scale
• Computational thermodynamic modelling of IL-metal systems
It is expected that the project will evolve around the design, synthesis and testing of novel ionic liquids for the extraction of trace (ppb-to-ppm) level metallic impurities from fuel streams, and the electrochemical recovery of those metals for purification and solvent recycling.
The position will be located within the Department of Chemical Engineering at Imperial College, and co-supervised through the industrial partner Shell. A successful candidate would be expected to have experience in either chemical engineering, chemistry, or within related disciplines.
As part of the degree programme, the student may have a short industrial placement at Shell.
Full funding for UK nationals (required) for 3 years
Studentship is available immediately and the post will remain open until filled
