And PhD is a whole another beast. It's a commitment that I'll have to think hard and carefully about.
I've considered the idea of doing PhD in Canada before, at the University of Toronto, or the University of Waterloo; not for PLT, but for networks which I was into back in the day. I'm not into networks as much anymore.
Is McGill University known for PLT? The other university I've considered is TU-Delft in the Netherlands, which does some things in the field of PLT.
However, it's been over 3 years since I graduated, and I'm not sure if I'd get glowing letters of recommendation from my prior schools at this point. To top it off, my master's degree focus was on OS, networks, and cybersecurity (the "systems" stuff). So, I'm definitely not going to get anybody to praise my abilities in PLT.
