Our group is always interested in new members to join our team of high-quality researchers and students. A number of opportunities exist for undergraduate, masters, PhD and post doctoral research positions.
The Centre for Doctoral Training in Aerosol Science
This newly funded CDT is offering a number of fully-funded PhD studentships in the area of aerosol science. The students will spend their first 7 months at Bristol taking courses in aerosol science before moving to their final university placement. A number of placements are available at Cambridge and are listed below. See http://www.bristol.ac.uk/cdt/aerosol-science/ to apply.
Filtration of charged aerosols (Cambridge): Conveying and generation of powders can lead to very high levels of charge on particles, affecting their transport, agglomeration and removal from the environment. By modelling and experiments, you will optimize collection of particles in filtration processes accounting for and manipulating electrostatic charge.
Synthesis of carbon nanotube fibers (Cambridge): Carbon nanotube fibres have superior properties of strength, thermal and electrical conductivity. They are produced by a high temperature catalytic nucleation process, which is poorly understood. You will use experimental (visualisation, spectroscopy, sampling) and numerical (reacting flow CFD) tools to understand how to increase process yield.
Non-uniform emission of pollutants and mixing in vehicle wakes (Cambridge): The emission of pollutants by vehicles from both exhaust and non-exhaust sources varies significantly in time, particularly in city driving. This project will examine the effect of time variation in vehicle emission rates using reduced-scale laboratory experiments, vehicle emission models and field measurements.
Modelling the plasma synthesis of graphene (Cambridge). Plasma synthesis offers a potential route for the bulk synthesis of graphene. The choice of process conditions and reactants is critical to avoid undesirable defects in the carbon structure. Through modelling, you will investigate the processes controlling the formation of graphene in plasmas.

Our research is aimed at scale-up production of carbon nanotube (CNT) materials from a floating catalyst chemical vapor deposition (FCCVD) process. Industrial production of CNTs from a gas-phase aerosol process, requires reactor scale-up and process densification. My work seeks to scale-up CNT production while controlling material chemistry. This work is a part of a larger Advanced Nanotube Application and Material initiative, www.anam.eng.cam.ac.uk.
Xiao Zhang received his PhD degree on Condensed Matter Physics from Prof. Sishen Xie’s group, in the Institute of Physics, Chinese Academy of Science, investigating the preparation of some novel carbon nanomaterials (especially ultralong suspended CNTs). He developed a novel optical visualization method for single tubes, with which intrinsic optical and thermal properties could be characterized. In University of Cambridge, during his research associate period at Department of Engineering, he will focus on the subject of CNT Synthesis and Characterization (especially on the thermal conductivity enhancement) by working together in the group of Dr. Adam Boies in Division of Energy, and the Nanomanufacturing group of Dr. Michael De Volder in Institute for Manufacturing.
My work within the Center for Sustainable Road Freight is to examine noxious and climate pollutants from heavy goods vehicles. A current focus is interpreting results from a variety of research projects within the Boies Lab. These projects include evaluating gaseous emissions collected with low cost sensors from individual heavy-duty vehicles which provide useful engine emission maps, and a separate project analysing correlations between low-cost and high-end instruments in their ability to measure particles in a laboratory setting as well as in ambient conditions.
George obtained his PhD in magnetic recording in 2013 from NSCR “Demokritos”. His main research interest is focused on magnetic materials and applications. He worked in EU projects regarding rare earth free permanent magnets as post-doctoral fellow between 2013 and 2018. Currently he is he is working in EMI shielding and magnetic properties of carbon nanotube (CNT) materials in the framework of Advanced Nanotube Applications.
My current research includes traffic and high resolution vehicle emissions modelling as part of the MAGIC Air (Managing Air for Greener Inner Cities) project, http://www.magic-air.uk. I have a background in Mathematics and worked as a transport modeller within industrial prior to this position.
My research seeks to produce catalyst particles from a spark discharge generator. I have constructed a spark generator to produce small (<10 nm) particles of precious metals (Pd, Pt and Au). Deposition of these materials onto ceramic monoliths allows for applications in automotive exhaust.
Jean de La Verpilliere
I am synthesizing hierarchical carbon nanomaterials (CNT) for energy applications. My research focuses on detailed study of aerosol synthesis of CNT sea urchins, consisting of a metal oxide core with carbon nanotubes grown radially from the core. Applications of the materials extend to thermal, electrical and energy applications.
I am developing a low-cost sensor for airborne nanoparticles suitable for environmental air quality monitoring. My research involves the study of aerosol nanoparticle behaviour including transport, electric charging and particle/ion recombination mechanisms using a combination of experimental and modelling techniques.
I am developing a system to synthesize carbon nanotube fibres and mats directly from the reactor, using microwave plasma in place of a tube furnace. The plasma system has several key advantages which include direct heat input to the carrier gas and reactants, high mass throughput, large temperature gradients which allow for precise control over reaction stages, and the ability to decouple reaction stages such as catalyst particle formation and nanotube growth. The ability to decouple reaction stages may help prevent thermal breakdown of methane and the subsequent formation of amorphous carbon, ultimately improving the quality and purity of the nanotube material.
I am developing a low-cost mobile sensor system for detection of airborn pollutants, including PM, NO, NO2, CO, CO2, O3, UHCs and SOx. The system will be mounted on Minneapolis buses for high spatial coverage of pollutant concentrations throughout the Twin Cities. This work will provide insights into pollutant “hot spots”, as well as develop methods for wide-scale deployment of wireless sensor systems.
My current research takes place in the Center for Sustainable Road Freight at the University of Cambridge. The project focuses on the development of a low-cost method of measuring greenhouse and noxious gas emissions from on-road vehicles, utilizing existing low-cost electrochemical sensors. The research seeks to measure this data in real-time through an existing Android app and accompanying software. The system will measure the emissions produced and the data will be used to help generate engine emissions maps for in-use vehicles.
My research focuses on aerosol instrumentation development, predominantly classifiers, and their novel applications. I am currently working on developing the theory and experimentally validating new applications of the Aerodynamic Aerosol Classifier (AAC). The AAC classifies nanoparticles based on their aerodynamic diameter, by inducing known drag and centrifugal forces on each particle, and thus avoids multiply-charging effects produced in electrostatic instruments. This work will allow the AAC to investigate current areas of interest to researchers and regulatory bodies, including aerosol characterization, charging and source generation (i.e. monodispersed calibration sources).
I’m investigating new methods to enhance the productivity of floating catalyst chemical vapor deposition (FCCVD) process mainly by incorporating a plasma enhanced (PE) system into the current process. I also wish to develop an in-situ technique to achieve better alignment of the CNT fibrils during the CNT nucleation stage by an intelligent implantation of a magnetic and/or electric field. Better alignment of the CNTs within the non-woven CNT mat or CNT fiber should immensely improve the CNT product macro-scale properties. By collaboration with the nanomanufacturing group of Dr. Michael De Volder I will also seek ways to utilize CNT products, produced by the FCCVD process, in energy related applications such as batteries or supercapacitors.
Cathy Zhou, 2018-Present: I am doing aerosol formation modelling of carbon nanotubes using OpenFOAM. Our main goal is to simulate the nucleation, condensation, and coagulation of particles within a continuous floating catalyst CVD reactor.
Josh Hassim, 2018-Present: I am researching the response of low cost pollution sensors to different environments including lab based and roadside chemistries. In particular I am investigating the signal correlation between instruments, as well as comparing how well these lower cost sensors can characterise the different size and chemistries in relation to more expensive devices.
