Personal profile

Former PhD student, funded by Oxford Instruments and Royal Holloway.

Platforms for new Quantum Technologies -Addressing the challenges in cooling and exploring the properties of strongly correlated electron systems, using current sensing noise thermometry

 

Educational background

Graduated in 2013 with a 2:1 in MSci Physics from Royal Holloway, University of London.

Teaching

During the full 3 years of my PhD studies I was a demonstrator and marker for a variety of undergraduate courses.

Other work

For my masters project, I worked within the Ultra Low Temperature group at Royal Holloway, building and testing a current sensing noise thermometer to mount onto both a dry demagnetisation cryostat and an adiabatic nuclear demagnetisation cryostat.

 

I participated in a lot of outreach work at both Royal Holloway and also in various schools and events.

These include presentations at open days to prospective students and their parents, and at science festival days on campus.

I presented an outreach talk on Superconductivity at a events at Royal Holloway to an audience of GCSE and A Level students and their families and I have taken shows on the road to schools throughout London and greater London.

Research interests

My research was based on designing the platforms used for new quantum technologies. I built and worked with various noise thermometers to accurately measure the temperature of these platforms and samples that are mounted on different stages of a dilution refrigerator. I developed this technique of measurement throughout my PhD thus far.

I also worked with 2DEG systems, (two dimensional electron gases) verifying the coldest temperature we can successfully cool these to, studying and improving various cooling techniques.
I worked with a wet dilution refrigerator and also with a dry dilution fridge, developing a nuclear demagnetisation stage mounted onto the dry fridge. This is so that a dry dilution refrigerator will be able to cool well below its base temperature of 10mK, down to 1mK, at the push of a button.
