What's been your biggest "aha!" moment of your research career?
“The biggest “aha!” moment of my research career occurred when I truly recognized the sophistication of language-minoritized childrens' verbal artistry and efficacy. More particularly, when I started to look closely at the forms and functions of Native American kids’ English language use, it was plain to me that I wasn’t witnessing just impoverished versions of what adults speak. What I saw was very complicated, sophisticated, and efficacious talk—in its own right! When I realized that Native American kids' talk had this kind of richness and power, I knew I was really on to something big. Ideologies in the dominant U.S. culture of what constitutes good speaking or good language use can be pretty narrow and limited to the extent that grammatical correctness is the main standard against which language use is measured. If we just open our eyes and ears to the ways of speaking used in different cultures, including the use of English in those cultures, we realize that there is such a wide array of beautifully artistic and highly efficacious talk, ways of speaking that most of us are not accustomed to hearing. There’s so much to learn about these ways of speaking. I'm trying to get at that everyday, what language-minoritized kids can do with language. I am especially interested in what they can do with language that isn't school sanctioned, language use that schools don’t see as legitimate or worthy. I'm looking at ways of speaking that are not considered “correct" by school standards but are, according to local cultural standards, just as expressive, just as artistic, just as efficacious as any language use that is validated in formal educational environments. When these non-dominant ways of speaking by language-minoritized kids are empirically specified, educators can then tap into these funds of linguistic knowledge and skill and build bridges to ways of speaking English that have more widespread social and cultural capital.”

What is your research?
I study heat flow and problems in math and physics using techniques of pure math. Most of the time I work on a problems that have physical motivation. My main interest is in the mathematical techniques that are used to tackle these problems.
Here is one example of a problem. Imagine a perfectly square room with perfectly insulated walls, so no heat can enter or leave the room. Now draw 16 floor tiles: half generate heat, and the other half absorb heat.Then create a second room, with the same size and insulation as the first. Move all of the hot tiles together in each column. The conjecture is that the second room will have a larger gap between the maximum and minimum temperature than the first. I proved this correct a few years ago, and I’m currently working on writing up my solution for the same problem in higher dimensions.
The most interesting part of my research to me are the techniques I use to solve these problems. I’m not a physicist, but I like to think I have good intuition for solving the problems.
What do you do when you get stuck?
If I get stuck with this research I try one of two things. First, I can try to solve an easier problem. Sometimes, solving that problem will give me insight or techniques that can carry over to the harder problem. Another option is to search the literature for similar problems. I focus my attention on the techniques that other researches use and try to adjust them to fit in my situation. Sometimes, I get lucky, and find something useful.
