I've been curious how many working researchers we've got in this community, and what you all do!

If you're working in science (physical or social), engineering, etc in a research capacity, give a shout in the comments and let us know what you work on! Same goes for students and amateur scientists at any level. (And by amateur I mean those of you who are working on your own experiments but just not being paid for it / not working on a degree; I'm upset that "amateur" has a negative connotation, it shouldn't.)

I'm currently a PhD candidate, working on transmission electron microscopy and electronic materials (mainly ferroelectrics). In the past I've been involved in research / product development in a few different industries, including medical devices, aerogels, and materials for RF devices.

Happy to have you! The science behind MRI is fascinating, and the machines themselves are really cool. Have you ever seen a magnet quench? I don't think they're really supposed to happen during normal operation, but some of the videos I've seen have been rather dramatic.

It is pretty crazy people were able to figure that all out and we are able obtain crazy detailed pictures without radiation.

No I haven't seen it! Hoping to see a controlled quench someday but also hoping to avoid needing to use it in any emergency situations; it'll have to be a damn near life/death situation to hit that button. Very costly decision. I guess there's also a dwindling supply of helium in the world so that could get interesting as time goes on.

Yeah, helium being a finite resource was something that really surprised me when I first learned about it! Better to keep it inside the MRI as much as possible for sure

helium recovery and recycling has come a long way, and the costs of helium are now justifying the extra expense of the hardware, so I think that problem should abate somewhat in the coming years.
