Mid to Low Frequency Quantamental

Hi, I am a sophomore in college - Finance Major, Math & CS minor. I did a quant internship after my freshman year, but with my background in mind, I am interested in the intersection of both fundamental and quantitative investing. 

As the title suggests, this background has brought me to the idea that mid to low frequency quantamental trading is where I feel that both my interests lie and my skillset would be most applicable. However, I fear that this is relatively niche and am unsure how to get to a desk that does something like this. So my questions are:

1) What can I do now (personal work like pitches, trading, research) + look for in a job that can set me up best for this? 

2) Would a masters be something I should definitely consider? I currently attend a target school but with lack of relevant opportunities and not being a stem major have been thinking of the more technical Masters or PHD of finance (Princeton, MIT)  along with masters in computational finance/ financial engineering (CMU, Baruch, Columbia, etc).

Any insight would be truly appreciated, thanks.
