Professor Olafson was an instructor at Starfleet Academy who taught the course Transporter Theory.

In 2369, Lieutenant Reginald Barclay could remember the day in Doctor Olafson's class on Transporter Theory when he talked about the body being converted into billions of kiloquads of data and... "no exist margin for error. One atom out of place and you never come back..." (TNG: "Realm of Fear")
