The stream of data on Twitter provides a rich source of information that can help us understand trends and viewpoints in real-time.

One can easily harness Twitter data in an automated way and create large, structured datasets. The ability to do this feels intuitively powerful — what can we learn from the infinite patient/physician chatter? — and I spent quite some time pondering the highest yield use cases.

I concluded that a particularly meaningful application of Twitter data is understanding gender disparities in radiology and how they are changing with time. This makes sense because:

  • There is a powerful movement…

One of the coolest machine learning stories in recent memory involved the Google Duplex, a voice A.I. capable of calling a restaurant and making your dinner reservation while pretending to be human:

Simulating a personal assistant is cool, but it would be cooler to simulate a highly trained physician and potentially save lives. And given the massive hype surrounding artificial intelligence, I think it is fair to be ambitious.

It was with this in mind that I took a break from my standard routine of “absolutely never…

As a hybrid physician/engineer, I spend a lot of time pondering how new platforms can empower doctors.

I am particularly excited about the potential of smart speakers coupled with advances in A.I. and natural language processing (also looking at you, blockchain). I am bullish on conversational agents in general, previously building an iOS chatbot powered by Watson that simulates a human radiologist. Chatbots are cool and useful, but voice — that might be magic.

Sensing potential, I decided to hunker down with my trusty corgi, drink a bunch of coffee, and start building the cool voice tools I want to…


I have been excited about conversational agents for some time, previously building an iOS chatbot simulating a human radiologist powered by Watson.

As a delightful weekend project, I sat down with my glorious corgi and lots of coffee and built a radiology assistant for Google Home. It is designed to assist healthcare providers with their radiology needs in a quick, conversational, hands-free way. Some video demonstrations:

Smart speakers are a revolutionary technology, and tools like Google Home and Amazon Echo have the potential to offer immense value in healthcare. …

Did you ever think we would have the technology to transform a modern bird into a prehistoric dinosaur? To, theoretically speaking, give a pig wings and make it fly? To evolve a mere cat into the far superior dog? Well, this is about to be you right now:

Soon, there may even be no cats.

Enter CRISPR, hailed by Forbes as the “next step” in human evolution. …

You have a brilliant machine learning idea, hard-earned technical ability, and the capacity for airtight execution. Nonetheless, a challenge remains: navigating the complex layers of bureaucracy needed to please “the man” and attain permission to share your technology with the world.

If you aren’t familiar with this meme structure, you need to step up your understanding of spicy memes.

Machine learning is clearly the hottest topic in HealthTech — you couldn’t use the restroom at RSNA 2017 without engaging in a discussion about whether A.I. beats radiologists at diagnosing pneumonia — yet most physicians have no understanding of the FDA approval process. …

There has been a lot of talk about Butterfly Network and their iQ ultrasound probe, which at first glance seems like just another point-of-care ultrasound probe in a saturated market. It certainly looks like the competition:

Can you spot the one that might change everything?

On closer examination, however, the iQ probe has features “under the hood” that make it considerably more powerful and interesting:

(A) It replaces the piezoelectric crystal with semiconductor chips.

This is the secret sauce. Traditional ultrasound works via piezoelectric crystals, where an oscillating crystal produces sound waves that generate an image. …
