Maddie Weinstein

I am an NSF postdoc at Stanford. My supervisor is Ravi Vakil.

I received my PhD from UC Berkeley in 2021, where my advisor was Bernd Sturmfels. My dissertation, Metric Algebraic Geometry, was awarded the Friedman Memorial Prize.

My current research interests include applied algebraic geometry, real algebraic geometry, intersection theory, topological data analysis, and the geometry of data.

I am honored to serve alongside these STEM role models as an American Association for the Advancement of Science IF/THEN Ambassador. Check out this collection for profiles of amazing women in STEM.

Here is my CV, updated October 2020.

Outreach

I am an American Association for the Advancement of Science IF/THEN Ambassador. In this program, I use various media platforms to inspire middle school girls to pursue STEM careers. I have enjoyed being a virtual guest speaker in several K-12 classrooms, reaching approximately 966 students as estimated by Nepris. I am excited to be part of the largest collection of statues of women.

As part of my application to the IF/THEN Ambassador program, I created a video in which I tried to give kids a sense of math research by explaining Topological Data Analysis. Thanks to Ozde Bayer for the videography!

Madeline Brandt and I made a video called MatheMaddie's Ice Cream Map, which you can view here. This video attempts to describe the ideas of the papers Voronoi Cells of Varieties and Voronoi Cells in Metric Algebraic Geometry of Plane Curves (listed above in "Research") to a general audience. We received an Honorable Mention in the NSF We Are Mathematics video competition.

For two years, Madeline Brandt and I ran Gender Equity in Mathematical Studies at UC Berkeley. We founded this group with a grant from the Institute for Advanced Study Women and Mathematics program and Lisa Simonyi as part of the Women and Mathematics Ambassadorship Program. Activities included a reading group to discuss articles on gender diversity in STEM, volunteering as math tutors at Willard Middle School in Berkeley, and events to support undergraduate math majors at Berkeley.
