0:00.0 | Kevin, thank you for coming, man. |
0:08.7 | Wow, thank you for having me. |
0:09.8 | I think you're the first NASA scientist I've ever talked to. |
0:13.8 | Wow, okay. |
0:15.4 | How did you get involved with NASA? |
0:17.7 | How did I get involved with NASA? |
0:19.4 | I had been... My PhD was in physics, and I had done work in studying the dynamics of the human |
0:30.0 | brain in response to auditory stimulation. |
0:34.6 | And I was studying magnetic fields generated by neurons. So magneto and |
0:39.0 | cephalography. And I was interested in how to separate brain signals. When you record |
0:49.7 | EEG by putting electrodes on the surface of the head or do magneto and cellulography. |
0:54.9 | Each detector picks up a mixture of signals. |
0:58.0 | So what you really want to know is what signals are coming from which different part of the brain, |
1:03.4 | but you really can only record mixtures. |
1:05.1 | So I'd worked on algorithms to separate mixed signals. |
1:10.5 | And these were AI algorithms. |
1:12.6 | This is in the late 90s before anybody heard of AI. |
1:15.6 | I've been doing the AI for 30 years, but we didn't call it AI. |
1:20.6 | They were machine learning algorithms, right? |
1:23.6 | And so I was doing work in neuroscience, but my PhD, my original interests were originally in physics. |
1:29.6 | And I got, I was at a neuroscience conference in D.C. and visited two of my friends who were married, an astrophysicist and an astronomer. |
1:42.8 | And so I started collaborating with the, with our astronomer |
