Advanced loop integration is universal to a wide range of problems in theoretical physics. I will discuss methods and concepts such as integral-by-parts relations (IBPs), differential equations (DEs), the role of the propagator pole displacement (iε), dimensional regularisation (d=4-2ε), and method of regions. The example of study will be two-loop integrals from our soon-to-appear paper on integration in the Post-Minkowskian expansion.
