an explosive thank you to all students voting for me everyday!!!

Favourite Thing: Becoming one of the best at what I do, at one point make my own discovery and using all this to improve imaging in healthcare! Trust me, there is no better reward or feeling than making a difference in a patient’s experience in a hospital.



Grammar School 2004-2008 , University College London 2010-2013 , Kings College London 2013-present


7 GCSEs, 5 A levels, BSc Physics with Medical Physics (UCL) and currently undertaking a part-time Master’s degree in Clinical Science (KCL)

Work History:

I was in the army for two years ( Green Berets) and then went of to university. I have been tutoring from 2010 and I am now working as a Trainee Clinical Scientist in London.

Current Job:

Medical Physicist (Trainee Clinical Scientist) in Imaging with Ionising Radiation


Kings College Hospital NHS Trust

Me and my work

I am a 25 year old physicist and I’m involved in using radiation for imaging and therapies in hospitals.


I am 25 years old and I graduated from University College London in 2013. I like going to the gym and I love Taekwondo! I love dogs (especially puppies) ! I wish they stayed like that all the time!

I love putting what I learn into practice and I believe that there is no better way to learn something unless you see it being done/used! That is why I chose medical physics! I love seeing all the maths and physics I have learnt being put into practice! Especially into helping patients!


I work in Nuclear Medicine and Diagnostic Radiology. I am involved in imaging patients using radiation and also using radiation for cancer therapies. Working with scanners worth more than a million pounds each! Right now I am completing a Clinical Scientist training scheme.

I also do some maths and physics tutoring for GCSE and A-level students. I love telling them how what I am teaching them will be useful at what point in their life and I give them loads of examples from my own work. But I HATE it when I have to teach them something just for the exam and they have to memorise definitions!

My Typical Day

Involved in getting the best images possible from patients and problem-solving

MY TYPICAL DAY : I wouldn’t be doing this if there was a typical day !!!! But here’s what I can think of 

  • I LEARN EVERYDAY: That’s the best part of my job I learn something new every day and that’s what I love about it.
  • Checking that all the machines used for imaging patients are performing well and at the best of their capabilities.
  • Processing images and trying to get numbers out of patients’ images. These numbers include information on how well the kidneys, the liver, the heart, the brain and the bladder are working.
  • Trying to solve day to day problems with scanners.
  • Trying to get the best images possible with the least radiation dose to patients.

What I'd do with the money

Use it to create demo kits of our scanners to explain what we do with radiation to children and students.

I would use the money to create a demonstration kit of our scanner with Legos and Raspberry Pi.

A lot of children visiting our department for a scan are sometimes scared and don’t know how it will be. By creating model replicas of our scanners using legos and Raspberry Pi we can show them before hand what will happen and that will hopefully make their experience better!

I would also use the kit during my visits to schools when explaining to other students what my job is and and how we use radiation to image patients.  This would make it a lot easier to show students how science is being used on a day to day basis in hospitals!  And how without scientists in hospitals nothing would work !

My Interview

How would you describe yourself in 3 words?

Cheeky, punctual, hungry

Who is your favourite singer or band?

Bruno Mars

What's your favourite food?

Shish kebabs

What is the most fun thing you've done?

Climbing a tower when I was in the army for two years. oh ye and then having to jump down …

What did you want to be after you left school?

Something involved with applying science in everyday life.

Were you ever in trouble at school?

I once hid in the library to skip my chemistry class :/

What was your favourite subject at school?


What's the best thing you've done as a scientist?

I helped reduce the time a very claustraphobic patient had to spend in a scanner for his pictures to be taken

What or who inspired you to become a scientist?

My physics teacher

If you weren't a scientist, what would you be?

I would probably have my own business

If you had 3 wishes for yourself what would they be? - be honest!

1) An Aston Martin 2) More time 3) Longer weekends

Tell us a joke.

Well,I tried to tell a chemistry joke at work the other day… No reaction.

Other stuff

Work photos:

This is my office! I don’t always have that much space all to myself!! I love my whiteboard! And I love working on two computers at the same time :).



Meet Mr Rando, the phantom we use to replicate and measure radiation exposure to patients. This guy is made up of 35 slabs of a material that has about the same properties as human tissue:


This is a SPECT/CT scanner we use in Nuclear Medicine to image patients that have been injected with radiation! I took this photo when we were doing some routine checks:


This is an MRI scan of some fruits I did when I was training in MRI. Can you guess what fruits they are?


A lot of students have been asking how we protect ourselves from radiation. So in the photos below you can see some of the things we use to protect ourselves. Including :

1) Lead syringe holders in various sizes which hold syringes which have radioactivity in them

2) Radiation meter to detect the amount of radiation in the room

3) Tongs ! For keeping the radioactive materials as far as possible from our fingers

4)Lead cases : We put the syringes in them and carry them to the room where we inject patients

5) Second photo : Lead glass shield! This shield has two parts : 1) the lead part which protects our chest and abdomen and 2) the glass part : this helps us see what we are doing  when we are handling radiation. The glass is very thick and has 15-18% lead inside! Something like a metal glass 🙂

Cheeky selfie 🙂


This is a Fluoroscopy unit it’s used to take pictures of patients using X-rays whilst they are in surgery!!! I  am very lucky to be involved with a lot of imaging equipment worth millions of pounds! Here we were trying to optimise the machine so that we could get the best images with the least amount of radiation!


This is a CT machine it’s used to create images of SLICES of our bodies again using X-rays! In this photo we are making sure everything works as it should!
