I'm graduating in two months (Pure Mathematics), and I'm planning to take 2019 to prepare for applying to PhD programs in the US (in Mathematics or Computer Science, depending on the program). I'm not applying this year because of time constraints. My interests lay within the broad area of logic. I particularly like (generally speaking) to design effective procedures that have a strong theoretical background.

My issue is the following: during the last few years, I have been exploring different research areas (ordered from oldest to newest: a little of BigData, cybersecurity, three full years in a software engineering research lab, and a research internship in Coding Theory. My MSc thesis was in ordinal notations and proof theory, a somewhat abstract logic subject - which I loved).

It's a complex story, but I can explain why I did it: I was exploring! I don't regret any of it, as it was really fun and I, as a human being, have many interests. Now I know I want to focus in logic. My questions are the following:

1) Does it have a negative impact that I tried so many different things?

I'm expecting the answer to be "it depends on how you tell the story". I like being passionate about more than one subject, but can it be a bad thing?

2) Should I focus 2019 on getting more research experience in logic?

I have no intentions in using my time just to apply to the US. I know the obvious answer to this question might seem to be "yes", but what I'm not sure about is whether I should put all my effort in more concrete experience in logic, or if I should round up the things I have already been doing - for example, I can continue the research I did in the Coding Theory internship, which was really interesting for me. Also, though I don't support hunting, 'a bird in the hand is worth two in the bush'. Anyway, of course it's not a binary decision.

Thank you very much for your time.

  • Why do you feel you need a year to prepare for grad school rather than applying now? – Jon Custer Nov 20 '18 at 15:04
  • That's a good question. I felt that if I did it this year it would be a poor application, as I was dedicating a lot of time to my thesis, teaching, and final exams. And I didn't want to leave everything I was doing aside, just for the application. – Guillermo Mosse Nov 20 '18 at 15:11

    Your application will be no poorer than those of all the other undergraduate math folks looking to go to grad school. Give it a shot this year - it really should not be a huge time commitment (particularly relative to taking an entire year off). – Jon Custer Nov 20 '18 at 15:52

Given that a doctorate is about depth in a small area, your option 2 sounds better to me as long as you have sufficient breadth of knowledge in your field already.

Note that many (most?) US students move to a doctoral program directly from their undergraduate program, so the "breadth" required is only about that required in a baccalaureate. So, I think, that except for the time factor you mention, you are likely well prepared now. But getting a bit of research going certainly won't hurt you, even if you have only minor results. You probably won't be working with a guide, after all. The area in which you do the research, however, might matter. It is better if it is closer to the sub-field that you actually want to work in.
