How do I deal politely with her?

There’s a woman in my friend group who has a PHD in physics. She keeps dominating the conversations discussing political and religious topics and using big words for all topics, to show off her intellect. I don’t want to be on bad terms with her, but I get irritated by this. Not jealous. I just don’t feel the need to show everyone how smart I am and rub others’ faces in it. She wouldn’t take it well if I pointed this out to her. Should I just avoid her?
