Finance to cancer research: student story

MPhys graduate Michal Tomaszewski  graduated as the top student on Mathematical Physics degree. Here he shares his story of gaining experience from various financial institutions before changing his path to cancer research.


When I was starting the masters year of my degree in Edinburgh, I was not sure what I would like to be doing. The several summer internships in the trading departments of investment banks, definitely helped my soft skills and business awareness, but I did not really feel like this is the work I would like to be doing for the years to come.

The idea of doing a PhD came to me as soon as I started the MPhys project I did with Dr Bartlomiej Waclaw in experimental biophysics. The exploratory nature of the work we did on the growth patterns of 3D bacterial colonies, trying to put together the various experimental and theoretical observations to make a coherent picture really appealed to me and I started looking online for PhD opportunities combining physics and biology.

While one needs to consider multiple factors such as the project formulation, research focus of the group and group leader, location and financial arrangements, the choice of a suitable PhD very much comes down to meeting the people and seeing the lab and the town – after all this is the environment you would be spending the next three to four years of your life in.

I graduated from the University of Edinburgh with an MPhys in Mathematical Physics in 2014 and went on to a PhD in cancer imaging at Cambridge University. I focus on the development of a new imaging technique to visualise the blood vessels in cancer tumour and measure their condition. The technology we are working with is called optoacoustics, and it relies on generation of ultrasound in the tissue following laser illumination. When the laser light gets absorbed, especially by strong absorbers such as haemoglobin in the blood, a small amount of heat is generated, causing thermal expansion and creation of a pressure wave which can get detected the same way as in traditional ultrasound imaging. During my work in Cambridge, I’ve developed a way to use this technology to gain insight into how well the tumour vasculature works, which gives doctors an indication of the aggressiveness of the disease and can guide the treatment.

Just like my work involves a mixture of physics and cancer biology, my affiliation is joint between the Department of Physics and the Cancer Research UK Cambridge Institute. The latter is where my experiments are, and where I spend most time. Working for Cancer Research UK is a great pleasure, as a generously funded Cambridge Institute greatly supports our research. Especially in the field of imaging, where open access to large and expensive scanners is essential, a well-equipped centre helps the researchers greatly.

I find the work I do incredibly exciting and fulfilling for many reasons:

  • the wide scope of the project, involving working with in vivo tumour models
  • using various imaging modalities and learning to use the equipment as well as
  • being involved on the technical side of signal and image processing
  • writing code…….makes the work very varied and interesting.

Working directly with a cancer research charity, collaborating with clinician scientists provides great motivation as we can feel our advances, although preclinical, could in the future make a real difference in clinical care.
