Interests and Expertise

A single night of poor sleep can lead people to do or say things they next day that they wish they hadn't. This is also true for parents and children. For example, poor sleep makes it harder for parents to keep their cool or a child to stay on task. Between age 2 and 4, kids stop napping, start resisting going to sleep, and may need comfort when awakened in the night. With sleep itself changing, it's difficult to understand how different sleep behaviors influence daytime behaviors and vice versa. Parenting, sleep, and daytime behavior are my core research interests. Specifically, I study the relation between sleep and parent–child communication. Well, I do this with many students—undergraduate and graduate—as well as colleagues. We measure sleep with questionnaires, daily sleep diaries, and actigraphy (watch-like devices). We observe parents and children interacting while they play with, and then clean up, toys either at home or in the lab. It takes a lot of people to collect, code, enter, and analyze data. One of my favorite parts about research is collaborating with students and colleagues as part of the Self-regulation, Early Experience and Development (SEED) Lab.
