My daughter has graduated from Lancaster this summer with a degree in physics, particle physics and cosmology at Lancaster. Its all under the term of physics now on the website, but the options are the same to go down the particle route. She did two internships in Tao neutrinos, and proton decay with DUNE, and she is now going onto Manchester to do a phd in neutrinos at an experiment in Spain. With physics you can branch out into various fields. One of her friends is going on into teaching, another 2 did their masters project with a company with a job at the end of it. 1 astrophysicist is taking a gap year before applying for phd's next year. Another is going into finance, and data science. She plans to finish her phd and go into either a research associate, going into nuclear physics maybe. As far as Im aware you can do a grad job in engineering with physics.
Lancaster is one of the top universities in physics. You want Relativity, quantum and particle physics. They do all of those, and they have good funding as well.
