Colloquium talk presented at the University of Arizona Mathematics Department. Abstract is below, slides are attached above. I also led a workshop using case studies, materials from that will not be posted publicly.

 

Abstract:

There are many reasons, moral or practical, why we need to diversify our mathematics departments — and more generally STEM departments — at all levels. But how do we go about pursuing this daunting and difficult goal of supporting diversity in mathematics?

In this talk I will try to convince you that doing a little every...

Supporting Underrepresented Groups at the Undergraduate Level, at Philadelphia, PA, Sunday, October 2, 2016:
diversity.pdf

This talk was the first of a minisymposium I organized at the SIAM ED16 Conference (SIAM's Applied Math Education Activity Group's first conference). The minisymposium was titled "Increasing Diversity and Inclusion in Mathematics: Some Inspiring Initiatives".

This talk gave a brief overview of initiatives and funding opportunities that aim to increase participation of minorities in...

A Diversity Training For Faculty And Graduate Students, at Philadelphia, PA, Sunday, October 2, 2016:
training.pdf

This talk actually consisted of a short diversity training through case studies. Attached slides show two case studies, but we only got through the first one during the actual training (25-30 minutes). The slides also contain some ground rules about what we expect of participants in such a training. Thanks to Professor Cynthia Anhalt of the University of Arizona for her help with writing the first case and running the training.

This talk was part of a minisymposium I...

Talk presented during the "Teaching Linear Algebra with Applications" minisymposium of the SIAM ED16 Conference. In this talk I described having students make a final project for a linear algebra course, and their presentations at a local science festival. Slides and audio for the talk can be found...

On "Averages" Saturday, February 27, 2016:

I ran a session of the Boston Teachers Math Circle on the topic of averages. We talked about different types of "averages": the arithmetic mean, the mode, the median... We even talked about the standard deviation, and other measures of spread.

But the bulk of the session was spent on exploring the fact that different data sets can have, for example, the same mean and the same standard deviation. Does that mean they "look" the same? You can find here my slides and my teaser flyer for this session.

A Placement Problem (not using test scores), at 51 Brattle Street, Grossman Common Room, Saturday, May 30, 2015:

I ran a session of the Boston Teachers Math Circle on the topic of modeling. The example we looked at was that of choosing the ideal placement of a park, knowing that four towns are sharing the costs of building it.

The objective of the session was to discover the process of modeling, and discuss the Common Core State Standards's Standard of Mathematical Practice:...

Partitioned Low Rank fast and Efficient Compression of Absorbing Boundary Conditions for the Helmholtz Equation, at Computational Sciences and Engineering Conference (SIAM CSE15) in Salt Lake City, Utah), Sunday, March 15, 2015:
slides.pdf

Abstract. Absorbing layers are sometimes required to be impractically thick to offer an accurate Absorbing Boundary Condition (ABC) for the Helmholtz equation in heterogeneous media. In previous work [BR and Demanet, submitted, 2014], we used matrix probing to compress an ABC from a few exterior Helmholtz solves with random Dirichlet data. We now present an algorithm (nearly linear in the dimension of the matrix) for applying this compressed ABC using Partitioned Low Rank matrices.
