Cohort 2

Our second cohort of 16 students joined us in September 2020

Alex Baddeley

Hey, I’m Alex, I’m from Hereford, a small city in the West Midlands. 

Before coming to university, I worked at an aerospace company, where I was part of the Antenna/RF design departments for 5 years. 

After leaving industry, I’ve gone on to study a BEng in Electrical and Electronic Engineering at Cardiff University, focusing on the RF and communications side. 

In my third year project, I worked on developing upon measurement software designed to apply Digital Pre-distortion to RF Power Amplifiers in order to demonstrate a designed Power Amplifier is linearisable.

My interests include hanging out with friends, going to the gym, travelling and exploring new places.

Richard Brown

Hi, my name is Richard and I’m originally from Southampton. I came to Cardiff three years ago to do a Bachelor’s Degree in physics, not really knowing what a compound semiconductor was but thinking it sounded really cool with important real world impact.

In the third year I was able to complete a project based around compound semiconductors in which I simulated a Gallium Arsenide based device with the aim to detect skin cancers using a technique found in retina imaging known as optical coherence tomography.

Outside of University I spend most of my time playing guitar in various bands which has given me the opportunity to perform all across the UK, record two original EPs and be featured on national TV and radio.

Arthur Collier

My name is Arthur and I’m from a small village in the South of England. Growing up, I had an unusually keen interest in Mathematics, Physics and Technology. I decided that a degree in Electrical and Electronic Engineering would neatly tie together my interests. With nothing around but fields and cows, I ventured to the University of Manchester, where I discovered that buildings regularly exceed two-storeys.

For my third year individual project, I researched triboelectric nanogenerators, which have potential applications powering remote electronics and harnessing tidal energy. Manufacturing required a variety of silicon nanostructure fabrication processes, including UV lithography and plasma etching. During my MEng project, I teamed up with three other students for a feasibility study investigating the potential application of Quantum Well Hall Effect sensors for Pulsed Eddy Current Testing. We designed a handheld scanner to image corrosion on pipes without the removal of cladding, laying the foundations for future QWHE-PECT systems.

Calum Dear

My name is Calum, I grew up in Bristol and have been living in Cardiff for the past 4 years. I received a BSc in Physics from Cardiff University in 2020. Associate IOP Member reading interests in photonics.

My final year BSc project interest was in using industry photonic simulation software to design and optimise an interferometer circuit on Gallium Arsenide (GaAs). The objective of the interferometer was to replace current Optical Coherence Tomography (OCT) techniques which currently involves large and expensive medical technology. Using 1300nm pulsed laser light, an algorithm was developed to determine spatial information from the optical circuit based on the interference pattern by spectrally diffracting the signal.

Aside from academia in Cardiff, I’ve had the privilege of working alongside amazing people in hospitality and was manager to a busy cocktail bar in the centre of Cardiff. I have skied for as long as I can remember, you’d have trouble keeping me away from snow.

Abi Enderson

Hi, my name’s Abi. I grew up in Devon where I completed A levels in maths, physics and chemistry, and went on to study my BSc in Physics with Astronomy at Cardiff University. Towards the end of my degree, I specialised in condensed matter physics and specifically semiconductors and their applications.

For my final year project, I created a simulation to model the properties of compound semiconductor waveguides based off their dimensions and refractive indices. Outside of my studies I enjoy running, hiking and practising yoga.

Daniel Johnson

Hi I’m Dan, originally from Essex. I completed a BSc in Physics at Hertfordshire and an MSc in Advanced Materials Science at UCL (Following time as a science teacher and a PGCE at Oxford) 
My MSc project was the characterisation of a novel single crystal transparent conducting oxide candidate using PXRD, XPS, and transport measurements.

I really enjoy getting hands on and spending time in the lab and I am excited to develop my skills further in the CDT program. 

I outside of my research and studies, I enjoy playing snooker, working on my own electronic projects, and anything outdoors with friends

James Meiklejohn

Hi, my name is James, and I’m originally from Edinburgh.

For my undergraduate degree I studied Natural Sciences at Cambridge, specialising in Astrophysics during my final year. After graduating, I moved to London to work as a software engineer at a startup designing wireless sensors.

I enjoy building things, running and cycling, and anything to do with bagpipes.

Khaya Mtunzi

Hi, my name is Khaya and I’m originally from Surrey. I completed my undergraduate degree in Physics at Swansea University and an MSc in Data-Intensive Astrophysics at Cardiff University the following year. I have been fortunate enough to gain a wealth of experience in astronomy and computer programming from both. 

My MSc project involved investigating the hexagonal wurtzite crystal structure of a gallium nitride thin film using the Fast Fourier Transform and correlating its surface morphology to its crystal structure. I hope to further enhance my understanding of semiconductor materials for space applications.  Outside of studying I enjoy playing the piano and guitar and trying to learn new languages

Tom Murphy

Since graduating from my Physics BSc at Queen Mary (University of London) in 2014, I have taken an unconventional route into industry. After leaving university I worked as a coffee roaster for various companies in London, eventually providing consultancy services for clients wishing to open their own coffee roastery. Once this line of work had run its course, I returned to education to study an MSc in Nanotechnology and Renewable Energy at Surrey University, where I worked on carbon nanotube rectifying antenna structures for energy scavenging for my dissertation.  

My first job in industry was working as a process engineer at IQE in Cardiff, where I assisted in the running of Aixtron G3 and G4 reactors, performing the epitaxial growth of GaAs and InP heterostructures. From there I moved to Nexperia in Manchester, working as a process engineer in the ‘Diffusion and Deposition’ department of a large Power MOSFET fab. Immediately prior to the acceptance of the CDT’s offer, I was working for Huawei R&D in Ipswich as a shift process engineer with oversight and involvement in all production processes, from deposition and etching to photolithography and metallisation. 

In my free time I used to enjoy attending concerts, competitive judo and climbing. Now I enjoy reading graphic novels, listening to music and cooking.

Diyar Othman

Hello, my name is Diyar and I am originally from Cyprus. I graduated from University of Manchester in 2020 with a BSc in Physics.

Before my third year started, I did a summer internship at the Jodrell Bank Discovery Centre, where I had a mainly public facing role. My third year project was on the future of energy, where I focused on the possibility of the world going 100% renewable by 2050. I did a case study in North Cyprus and focused mainly on solar and wind energy.

Outside of physics, I enjoy doing any kinds of sports, listening to and playing music and reading.

Oliver Pinna

I’m Olly and I’m an Italian student of the CDT in compound semiconductor manufacturing. 

I graduated at Cardiff university with a Physics Bsc. My interest in compound semiconductor manufacturing was developed within the Bsc with the studies of condensed matter physics, laser physics and semiconductor device physics together with my final year project. 

The project was on GaN (Gallium Nitride) nanostructures. Its main aim was to study and improve their growth process to able produce high quality nanostructures which can be very useful for solid state devices. 

My other interests in life include outdoor sports such as hiking and running and indoor such as yoga. 

I am also quite passionate about humanities, especially history and philosophy. 

Apart from this, in my free time I am always happy to have a good chat and a pint of beer.

During the CDT, I look forward to learn more about high quality semiconductor device production to be able to tackle the needs of society. I also look forward to improve my soft skills to become a well rounded professional figure. 

Iwan Pullen

Hi I’m Iwan, I’m from North Wales and I graduated from Cardiff University with a BSc in physics with astronomy. Although I selected the astronomy route for my undergraduate degree, I also had the opportunity to study condensed matter physics. It was through this I developed my interest in semiconductors and their applications. 

My final year project involved the writing of a program in Python to fit spectral energy density curves to a supernova at different points across a 2 year observing period. Treating the supernova as an emitting blackbody, I was able to determine the temperature and radius evolutions and make estimates of the total energy released in the explosion.

Outside of physics, I am a member of Cardiff University Triathlon Club and can usually be found in a swimming pool, on my bike or composing, playing or listening to music. 

Ben Salmond

Hi, my name is Ben and I’m from Carnoustie in Scotland. Recently, I have studied at the University of Glasgow for an MSc in Nanoscience and Nanotechnology. Prior to this I completed my undergraduate degree at the University of Strathclyde in Physics.

My masters project focussed on developing an equivalent circuit model for field effect transistors using the emerging semiconductor material gallium oxide. In my undergraduate degree, my final year project investigated the colour stability of light-emitting diodes. This work investigated both the effect of temperature change in the devices as well as the effect of the internal electric field in gallium nitride-based LEDs.

Outside of academia, I enjoy playing golf, road cycling and cooking.

Wesley Sampson

Hi, my name is Wesley. I am originally from Ringwood, just outside Bournemouth and I graduated with a BEng from Cardiff University in Electrical and Electronic Engineering and I am just about to complete an MSc at Cardiff University in Compound Semiconductor Electronics.

My undergraduate project was on utilising digitally programable components to develop tuneable filters.

In my Masters my project involved developing diode detectors utilising GaN on Silicon diodes that had been fabricated in house and producing simulation models that represent these diodes over a large frequency range and different Bias points.

Shirin Seifi

I am a postgraduate student at the school of Physics and Astronomy, Cardiff University. I have a Bachelor of Electrical and Electronic Engineering and a Master of science in Nanoscience to Nanotechnology. My MSc Thesis and Summer Project: Modelling Conductive Properties of Carbon Nanotubes in Infrared and Visible frequencies.

My bachelor Research Project was Modelling Properties of Nanoscale Arrays of Nobel Metals (Gold and silver) in visible and infrared frequencies. In my free time I like to play the violin and write songs.

Chris Walsh

Hi I’m Chris, I studied MEng Electronic Engineering at the University of Manchester.

For my third-year individual project I investigated solution based processes to manufacture thin film transistors. This involved manufacturing the transistors in a clean room, testing the devices and then analysing the data to determine their characteristics using labview and matlab.

My MEng team project aimed to develop a Industry 4.0 solution for the university’s mechanical workshop. This involved the development of both embedded software and cloud computing to extract and manipulate machinery data to analyse trends over time.
