Internal Transfer to Research

I'm a long time reader of WSO but this is my first post so please bear with me.

For context- In may, I graduated from a target school (Harvard/Princeton/Wharton) with a 3.8 + GPA and a return offer to the S&T division of the BB bank where I was a Summer Analyst last summer. I begin full time this summer. My career goal and dream job is to be in an investment role at a hedge fund or asset manager. I chose S&T because I was most interested in a global macro strategy at the time and believed the work would be highly stimulating from an intellectual perspective.

Since accepting my full time offer, my views on the subject have changed a bit. First, I have grown less attached to the need to be at a macro fund and more attracted to a L/S equity fund. Second, I am growing more and more worried about the direction of S&T at investment banks (regulation and automation).

As a result, I have become increasingly interested in the idea of pursuing a research based role in place of a trading role. I would be interested in equity research (with the goal of eventually working at a L/S fund) or rates/FX/macro research (with the goal of eventually working at a macro fund). I am fully prepared to treat the preparation that I have done for a trading role as a sunk cost if this is no longer my best career move.

I am posting here for two reasons:
1. Would this switch better position me to eventually work in an investment role at an asset manager or hedge fund?
2. What advice do you have on making such a switch as soon as possible either within my current BB or at another?

Thank you for your help!
