An invisible dance takes place inside our bodies. Moving atoms collide and form larger molecules, such as proteins. This dance cannot be seen with a normal microscope. This is why I use a virtual microscope — computers like this one — to create models that visualise the movement of atoms and molecules. I focus on G proteins , molecules in our cells that help regulate processes such as cell growth. When these proteins mutate, they can lead to serious diseases, including cancer.. Using my virtual microscope, laboratory research and artificial intelligence I study how such mutations change what happens inside the cell. This enables us to develop targeted medicines that can influence or repair these changes. After all, if we understand the dance of atoms, we may one day be able to re-choreograph it.
