This is her youtube channel. If you haven't read the paper on this algorithm, I think you can get a good intuitive understanding by watching the two videos she has on there from (what looks like) her thesis, and I think it becomes clear why she was selected to lead this project.

Specifically, these two videos:

and

https://www.youtube.com/watch?v=7NhQ7WkbHms

So, consider that these two videos are basically the "one-dimensional" solution, or one pin-hole camera example. In the approach that her and her team to image the black hole, they used many, many radio antennas', all acting in concert in a not-too different version of what she did her for the work on her YT channel.

Her happiness is contagious!

She was on one of the teams that did if I remember correctly. I believe they split up into three teams and developed algorithms independently from one another. What surprised everyone was when they came back, all three teams had more or less the same image. It’s been a while so I may be wrong on some details. But it wasn’t just her is my point.

Yeah it's cool but where meme?

Dude in the back is looking at the result with the same intensity as a teenager seeing boobs for the first time.
