Simon Jarrett would be well known?

[frictionalfan]

I'm just starting my second play through of the game and I had a thought about Simon and Catherine's first encounter via comm.

Why is it that Catherine, initiator of the brain scans on Pathos-II, doesn't recognize Simon's name when he introduces himself? Isn't it Simon's scan that revolutionized the scanning? Seems to me like his would be well known among doctors and scientists. Why then had Catherine never heard of him?

I might be forgetting certain dialogue or details. Some insight? (Sorry if the topic has been broached already!)
