# About Me

I am a commutative algebraist from Severn, Maryland. My graduate degree is from Cornell University in 2011, and my undergraduate degree is from St. Mary's College of Maryland in 2004.

I am also a recent Project NExT Fellow (Silver Dot, 2012-2013) and a Section NExT Fellow for the MD-DC-VA section(2011-2012).

## Primary Research Interests

My research primarily focused on computing the projective dimension, regularity, and Betti numbers of special classes of ideals over polynomial rings. In particular, my thesis results were focused on:

- Stabilization of Betti diagrams of powers of equigenerated ideals \(I\).
- Constructing linear quotient orderings on special classes of monomial ideals.
- Bounding the degrees of syzygies of r-generated edge ideals in degree 2 in terms of smallest induced cycle \(C_k\).
- Construction and resolution of nerve complexes related to edge ideals, using them to study properties of graphs on subgraphs rather than induced subgraphs.
- Bounding the regularity or projective dimension of an ideal \(I = (f_1,...,f_k)\subseteq\Bbbk[x_1,..,x_n]\) in terms of the degree of its generators, independent of \(n\), constructing ideals with a high projective dimension relative to the fixed numbers and degrees of generators.

My current research has moved into producing explicit resolutions of residue fields \(\Bbbk\) over quotient rings \(S=\Bbbk[x_1,..,x_n]/M\), where \(M=(m_1,..,m_r)\) is a monomial ideal. This extends results of Berglund, Blasiak and Hersh on the Poincaré series of such rings \(S\).

### Undergraduate Research Group

In Summer 2012, I had two undergraduate research students working on
a project on the *Combinatorics of the Mandelbrot Set*. In
particular, they focused on identifying points in the Mandelbrot set
with orbit patterns corresponding to \(H\)-compositions of numbers
\(n\in{\mathbb N}\), classifying and counting points \(x\in{\mathbb R}\) with
period \(n\) by their combinatorial type, and producing explicit
coefficients of infinitely iterated Multibrot polynomials.

There is a paper in preparation on the last of these results, and
both students attended *MathFest 2012* in Madison, WI to
present their work.
