Polyvagal Theory
Polyvagal theory explains how the physical body switches between survival and "rest and digest" states. The purpose of my therapy is to train your body to stay in rest state (this doesn't mean literal rest; it's when we are performing daily functions, like digesting, resting, socializing, and decision-making in a healthy, grounded way). This isn't necessarily a method in itself; it's a framework through which I do the other listed methods. You can read more about it here:
EMDR
Eye Movement Desensitization and Reprocessing uses eye movements to process traumatic memories, similar to how REM sleep processes the previous day's memories. When these traumatic memories have been reprocessed, it greatly reduces or eliminates their impact on our daily life. This is one of the most effective treatments we have for trauma therapy. You can read more about it here on the official EMDR website:

Brainspotting
Brainspotting also uses eye movements to process traumatic memories, but it differs from EMDR in a few ways; it is less structured, more intuitive, and uses fixed positions for the eye rather than movements. It is evidence-based and highly effective for trauma. You can read more about it here on the official Brainspotting website:
Parts/Ego States
Parts work (also known as ego states) is a way to heal traumas by working with the part of you that carries the pain, which can show up as a version of you. This is a bit tough to explain briefly here, but I'm happy to discuss it further with you. I often do parts work in conjunction with Brainspotting; this is a highly effective method that uses both talk and somatic therapy at the same time.
This article by Annie Wright, LMFT, gives a pretty good basic explanation.
