### ‘Amazing’ Math Bridge Extended Beyond Fermat’s Last Theorem

April 6, 2020 — Mathematicians have figured out how to expand the reach of a mysterious bridge connecting two distant continents in the mathematical world.### What Is the Geometry of the Universe?

March 16, 2020 — In our mind’s eye, the universe seems to go on forever. But using geometry we can explore a variety of three-dimensional shapes that offer alternatives to “ordinary” infinite space.### Multiplication Hits the Speed Limit

January, 2020 — A paper posted online in March 2019 presents what may be essentially the fastest possible algorithm for one of the oldest problems in mathematics: whole number multiplication.### A Breakthrough in Graph Theory

December 23, 2019 — A counterexample to Hedetniemi's conjecture### How Do We Think About Higher Dimensions?

November 4, 2019 — Panel discussion with Alex Eskin, Emmy Murphy and Terry Tao### Decades-Old Computer Science Conjecture Solved in Two Pages

July 25, 2019 — A paper posted online this month has settled a nearly 30-year-old conjecture about the structure of the fundamental building blocks of computer circuits. This “sensitivity” conjecture has stumped many of the most prominent computer scientists over the years, yet the new proof is so simple that one researcher summed it up in a single tweet.### Good Algorithms Make Good Neighbors

July 2019 — A host of different tasks—such as identifying the song in a database most similar to your favorite song, or the drug most likely to interact with a given molecule—have the same basic problem at their core: finding the point in a dataset that is closest to a given point.### 53-Year-Old Network Coloring Conjecture Is Disproved

June 17, 2019 — In just three pages, a Russian mathematician has presented a better way to color certain types of networks than many experts thought possible.### Out of a Magic Math Function, One Solution to Rule Them All

May 13, 2019 — Mathematicians have used “magic functions” to prove that two highly symmetric lattices solve a myriad of problems in eight- and 24-dimensional space.### Karen Uhlenbeck, Uniter of Geometry and Analysis, Wins Abel Prize

March 19, 2019 — A founder of modern geometric analysis who produced “some of the most dramatic advances in mathematics in the last 40 years,” Uhlenbeck is the first woman to be awarded this top honor.### Math Duo Maps the Infinite Terrain of Minimal Surfaces

March 12, 2019 — A pair of mathematicians has built on an obscure, 30-year-old mathematical theory to show that soap-filmlike minimal surfaces appear abundantly in a wide range of shapes.### Jean Bourgain (1954–2018)

February 6, 2019 — Over the course of a wildly prolific career, Belgian mathematician Jean Bourgain would repeatedly enter some area, solve several of its outstanding problems and create an entirely new field of study in the process.### A Collector of Math and Physics Surprises

November 27, 2018 — Tadashi Tokieda lives in a world in which ordinary objects do extraordinary things. Jars of rice refuse to roll down ramps. Strips of paper slip past solid obstacles. Balls swirling inside a bowl switch direction when more balls join them. Yet Tokieda’s world is none other than our own. His public mathematics lectures could easily be mistaken for magic shows, but there’s no sleight of hand, no hidden compartments, no trick deck of cards.### Mystery Math Whiz and Novelist Advance Permutation Problem

November 5, 2018 — A new proof from the Australian science fiction writer Greg Egan and a 2011 proof anonymously posted online are now being hailed as significant advances on a puzzle mathematicians have been studying for at least 25 years.### Graduate Student Solves Quantum Verification Problem

October 8, 2018 — Urmila Mahadev spent eight years in graduate school solving one of the most basic questions in quantum computation: How do you know whether a quantum computer has done anything quantum at all?### Titans of Mathematics Clash Over Epic Proof of ABC Conjecture

Sept 20, 2018 — Two mathematicians have found what they say is a hole at the heart of a proof that has convulsed the mathematics community for nearly six years.

I have been writing about mathematics and science for a popular audience for more than 20 years. A mathematician before I became a full-time journalist, I try to convey the essence of complex mathematical ideas to non-mathematicians, and give them a sense of the beauty and depth of mathematics.

I also enjoy plunging into topics far from my mathematical roots, and have written about fields such as economics, computer science, medicine, and biology — often as these fields relate to mathematics, but often simply for their own sake.

As a freelance journalist based in Berkeley, California, I have written for many publications, including Quanta Magazine, Nature, ScientificAmerican.com, New Scientist, American Scientist, Wired.com, Nautilus, and Science News, for which I was the mathematics correspondent for several years. I've also been the journalist in residence at the Mathematical Sciences Research Institute in Berkeley and at the Simons Institute for the Theory of Computing at the University of California, Berkeley. My work has been reprinted in the 2010, 2011, 2016 and 2020 volumes of "The Best Writing on Mathematics."

I received the 2021 Communications Award from the Joint Policy Board for Mathematics, which recognizes journalists and other communicators who, on a sustained basis, bring accurate mathematical information to nonmathematical audiences.

I am a graduate of the science writing program at the University of California, Santa Cruz, and I have a Ph.D. in mathematics from Stony Brook University.
