Okay, so Michel DeGraff is a person who studies languages and how they work. You know how you speak English, and other people speak other languages like French or Spanish? Well, Michel DeGraff is interested in how those languages are different and how they are the same.
He's also really interested in how we can use language to help people learn and understand things better. For example, if you were learning a new subject in school and the teacher was speaking in a language you didn't understand very well, you might have a hard time learning the material. Michel DeGraff believes that by teaching in a language that students are more comfortable with, they will be able to learn more easily.
He's also really cool because he's from Haiti, and he wants to make sure that Haitian Creole (which is a language spoken in Haiti) is recognized and respected. He thinks that if more people learn about Haitian Creole, it will help to preserve the culture and traditions of the Haitian people.
Overall, Michel DeGraff is a really smart person who cares about languages and wants to make sure that everyone can learn and understand things easily, no matter what language they speak.
