Research in Algo Trading is not a good choice?

[WilfredChai]

Hi all,

I have some doubt and would like to seek advice from you all.

Recently I am seeking for supervisor for Phd studies.

I have mentioned to some professors that I would like to do a thesis about algo trading framework with artificial intelligent neural networks.

However, two professors replied me that this topic is not a good topic as most publications about algo trading framework were published in low tier journal and the framework proposed are not practical.

May you all agree with them too?

If it is true I am seeking for advice, what kind of research or topic will help me more in being a quant after graduation.

I appreciated you all can provide me some advice.

Thanks a million.
