I'm MSc of Biochemistry and I have just experienced Molecular biology techniques and a bit biochemical methods, but I would like to continue my studies in Neuroscience.
Have I chance for this field?
You can check my published articles in my RG page.
I guess yes.. Switching field for PhD should not be a problem.. I guess you need to have a good basic idea on whichever field you want to go and convince your Boss that you can do the work. You learn how to work in PhD and your Research Group will help you to learn whatever you need to.
