Probably the best practice is to group these items and break them into different sentences.
My graduate education enabled me gainfully employ the basic laws of physics and their applications: Maxwell’s equations, lumped circuit abstractions, and amplifier abstraction. I have also worked in the digital domain, using combinational logic, clocked systems, instructions set abstraction, high level language, operating systems, and software abstractions. Finally I am experienced in the analog domain, using operational amplifiers, oscillators, power supplies, rotating machines, power transmission and distribution.
You can also use semicolons to separate groups and then commas to separate items within each group, but this is a long, painful sentence and readers usually don't appreciate that.
