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.
PhD or Post Doctoral Position – PEMS4Nano
The European Union-funded PEMS4Nano (PEMS4nano.eu) project is seeking a researcher with experience in aerosol measurement of emissions. The successful candidate will be a motivated researcher seeking to advance measurement of emissions down to 10 nm and below for on-road measurement of vehicle exhaust. The work conducted at the University of Cambridge will focus on the development of solid and semi-volatile particle measurement. The research seeks to improve catalytic strippers for solid particle penetration for particles at and below 10 nm, while additionally developing new methods to measure semi-volatile species.
The two year project (1 year + 1 year extension) can provide funding for a post doctoral researcher or researcher with a MS degree seeking to do a PhD. For applicants wishing to complete a PhD, an additional 1+ year (3+ year PhD) of funding will need to be identified from personal contributions or fellowships. Project management and entrepreneurship are highly valued, as it is likely that portions of the work will be commercialized.

Our research seeks to develop new methods for analyzing emissions from light duty and heavy goods vehicles. As a part of the Centre of Sustainable Road Freight, www.csrf.ac.uk, we are developing tools to analyze on-road emissions data collected from portable emissions measurement, PEMs, equipment. These tools serve to create engine maps and conduct drive train simulation for high spatial and temporal resolution emissions and fuel economy prediction.
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.
Extrapolating the properties of individual carbon nanotubes (CNTs) into macro-scale CNT materials using a continuous and cost effective process offers enormous potential for a variety of applications. My research explores a floating catalyst chemical vapour deposition (FCCVD) method to bridge the gap between generating nano- and macro-scale CNT material and has already been adopted by industry for exploitation. A deep understanding of the phenomena that occur within the FCCVD reactor and how to control the formation of the catalyst nanoparticles is, therefore, essential to producing a desired CNT product and successfully scaling up the FCCVD process.
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.

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.
I am working with the PEMS4Nano group as they work to develop mobile measurement procedures for particles with mobility diameters down to 10 nm. My main role will be to create a new catalytic stripper which will be able to be used in real world tests of vehicle emissions while also meeting the new particle penetration and semi volatile removal targets of the group.
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).
CNT sea urchins are composed of a metal oxide core with carbon nanotubes grown radially from the core. Currently, their production is limited by the initial concentration of the metallic salts in the aqueous solution in the CVD process. My research focuses on optimizing the output of CNT sea urchins by circumventing this limitation.
