IamA radiologist, AI researcher and lead author of a recent paper that used deep learning to predict if patients will die in the next five years. AMA!
Update: Hi everyone, thanks for the questions. I'm going to have to call it a night here (it is getting late in Australia, and I have another media interview in the morning). I can come back on after that and answer any other burning questions though (if that is allowed in the sub?). Thanks again!
Update 2: I think that I'll end the AMA here. Thanks for all the great questions everyone. I hope I answered most of it (there were some duplicates, so check the other responses if I didn't get to you).
My short bio:
I am a radiologist, which is a doctor who analyses medical images (like X-rays, CT scans, MRIs, and so on). I am also doing a PhD in medical artificial intelligence at the University of Adelaide, where I build and test deep learning (and other machine learning) systems to detect disease in medical images. It is super fun, really rewarding, and I get to work with a fantastic team of world-class researchers.
Our recent publication has generated a lot of media attention and spent most of yesterday at the top of r/futurology (over 9000 upvotes!). Several people asked me to do an AMA in the comments, so here I am.
The research in short
In this paper we trained a deep neural network to predict which patients would die within five years from their CT chest scans. This is a proof-of-concept study with a modest dataset, which we are building on now with further research (with tens of thousands of patients).
We use mortality to estimate how healthy each patient is, because there is such a strong relationship between the two. The goal isn't predicting how long you will live per se, but to quantify how healthy you are, and to work out whether we can do something to help you be healthier. This is called "precision medicine", using data to tailor treatment to each patient.

I also have a popular blog about medical AI, where I am currently doing an in-depth exploration of claims that AI systems will take the jobs of human doctors.
I've blogged on my predictions for medical AI in 2017, and they are looking pretty much spot on.
So ask me anything!

I will start answering questions in about half an hour, and will continue for a couple of hours if there is enough interest.
