I am an Assistant Professor at Michigan State University, with a joint appointment in the Dept. of Teacher Education (in the College of Education) and the Program in Mathematics Education (in the College of Natural Sciences). My Ph.D (2009) is from the University of Michigan, and was a joint degree in Mathematics and Education awarded by the Mathematics Department and the School of Education.

My dissertation focused on the capacity of the secondary Geometry course to faithfully represent authentic mathematical values and practices, and the extent to which school mathematics can cultivate a mathematical sensibility in students. Current research interests include an analysis of the secondary "Algebra 2" course, and an investigation into the mathematics education practices of home-educated students.

comment Examples of intuition from fields other than Physics to solve math problems
@Olivier - It has been a while since I read the Aczel book, but the impression I got from it was that Bourbaki was part of the Structuralist movement, and that the influence went in both directions simultaneously. I may be misremembering -- and even if I am remembering correctly, I can't vouch for the accuracy of Aczel's account. It did seem to me at the time that Aczel was exaggerating the connection between Bourbaki and the Structuralists to make a better story.

comment Rings for which no polynomial induces the zero function
Let $R$ be the ring $\mathbb{Z}/p \mathbb{Z}$ with infinitely many elements $u_i$ adjoined, each satisfying the relation $u_i^p -u_i = 0$. Then the polynomial $p=x^p-x$ satisfies $\hat{p}=0$.

comment Rings for which no polynomial induces the zero function
P Vanchinathan, yes, that was one of my examples. More precisely if $R$ is a ring that has my desired property, than $R \times R$ also has the desired property, even though it is not a domain. So that shows that "infinite domain" is not necessary for this property.

comment Lost soul: loneliness in pursing math. Advice needed.
When I was in my 1st year of grad school I got married; in my 3rd year we had our first child. I missed a lot of classes, and a lot of deadlines, and was worried that he consequences might be dire. But my professors all -- all, without exception -- told me not to worry: "Some things are more important than math", said one, and that advice has kept me (reasonably) sane and balanced. I hope it helps you too.

comment A weird function related to the denominators of rational squares
Only in the most elementary case: \sigma (a) = 2 iff $a=n^2 + n$ for some $n$.

comment A weird function related to the denominators of rational squares
Thanks -- those citations will be very helpful, I think. I am a total newbie when it comes to the OEIS; is there a way to search for papers / pages that discuss or reference a specific OEIS sequence?

comment A weird function related to the denominators of rational squares
Plus I've got a list of 20 special cases that have the form: If $a=n^2 + $ [something], then $\sigma (a) = $ [some specific linear polynomial in n with simple coefficiets]. But I can't find a way to tie those 20 special cases together into a general statement.
