Research statement for second time PhD applications to a different graduate program
Since you are entering a different field, the new SoP should be specific to that field. What are your future plans and how do you expect to achieve them? The &quot;tone&quot; of it can be similar to what you wrote before, but the details will be different.
What areas do you hope to explore? What do you intend to do with the knowledge you gain? What sorts of research do you want to work on?
Let the SoP speak to your proposed future in the new field. Having a bit more experience than you did before you can probably be a bit more specific.
