She does meet Ash on a few occasions, most notably whenever she meets him the first time, and becomes infatuated with Pikachu and Raboot, caressing their ears and generally playing with them. However, she mostly spends time with Goh or Leon during her investigations into the Darkest Day. So she’s not a massive traveling companion like Misty or May was to Ash, and mostly follows her own story in the background, giving aid and support to the main characters as needed whenever she learns more from her research.
