 Hello everyone, my name is Carlos, I'm from Colombia and I'm a PhD student at the UCL Medical Physics and Bioengineering Department and my research focuses on the development of new X-ray imaging technologies, basically to push the technology so that you can see things that were invisible to X-rays until now. What inspired me to work in this field? Well, I was trained originally as a physicist and I was always looking forward to see the application of what I was learning. And I think medical physics gave me a very meaningful field in which I could apply my skills basically to improve people's health, which I think is one of the most important things to work for at the moment. The medical physicists that I am are, these will very likely be William Rungen or Honesfield, basically the first one discovered X-rays almost by chance and the second one pushed the technology to a level in which found a bunch of applications across different fields in the medical sciences, which was basically the invention of computer tomography. Where at the moment the most exciting thing about medical physics is being involved in a field, in general healthcare, that I believe as many of us suffer because of the pandemic, it's going to be a really key field to work, especially towards developing novel technologies that improve people's health, but also that make healthcare systems much more equal. So that's it for me. Thank you and a happy day of medical physics.
