Current and next-generation Cosmic Microwave Background (CMB) surveys will measure the anisotropies of the CMB with unprecedented precision. Complementary to other laboratory and astrophysical searches, these measurements provide a probe to search for physics beyond the Standard Model. In this talk, I will discuss some applications of this data to search for signatures of dark sector interactions, such as dark matter-baryon scattering. I will present results leveraging the SPT-3G 2018 temperature and polarization data set to constrain these interactions and discuss the challenges faced by this and future analyses. Furthermore, I will also present candl, a Python package in which we have implemented an automatically differentiable likelihood for analysing both primary CMB and lensing power spectrum measurements.
