She has a Doctorate in quantum chemistry. I am a Chartered Chemist, and was one of the earlier adopters of computers in chemistry. I was (in a a very minor way) one of the people who helped move chemistry from minicomputers to PCs. Almost all chemistry relies heavily on computers, but physical scientists generally consider computing to be just a necessary tool and not an end in itself.
I started doing serious computing stuff when I had to write a laboratory management system, and a later a financial management system, that would run on a number of LANs connected by a WAN. This included specifying and purchasing and installing equipment and staff training. My "qualifications" were the experience of running a chromatography and high-resolution mass spectrometry laboratory for the organization. This involved connecting together systems that run on DECnet, Token Ring, RDOS, PDPs, VAXen, UNIX minis, PC DOS, CP/M, POS, the Apple ][, and a whole pile of other assorted equipment with serial ports. My recollection was that this was pretty easy compared to mass spectrometry...
Incidentally as a subtle, but good-hearted, dig at people who "know computing", I was put in charge of computing for 300 scientists (>400 computers) by an organization that did not believe in "putting computer people in charge of computing". Their rational was that people who "did computing" did not always see the needs of the business, and were just as likely to set up systems with a 4GL or Java or whatever was becoming cool at the time because "it was interesting" - Particularly if it helped their career development.
Angela is a bit younger than me; but back then, even in East Germany, she would have required a fairly detailed understanding of computers to get a Doctorate in quantum chemistry. I expect that nowadays she might be too busy to look after her own computer, so she probably relied on a professional [expert],[security officer],[self-important bureaucrat].
Disclosure: I learnt FORTRAN as an essential part of my chemistry course in 1969, so my mind is probably damaged - All of the above may, probably, be disregarded.
