Thank you for the question! 🙂
I think I’ll give two answers: In my PhD I have found a new way by which the virus I study (Vaccinia Virus) tricks the immune system of the cells it infects. There is a process called autophagy which cells use to ‘eat’ incoming pathogens up so they are not dangerous anymore. Some viruses have found a way to escape autophagy and my virus found a way that is very different from other ones previously known and I discovered that :).
Another thing I was involved in is that I worked for a pharma company during my Masters degree. There we developed a screening mechanism to identify not chemicals that could be used as cancer drugs. I was only a very small part in a big project but its great to think that I helped in the development of something that treats cancer.
