### Mathematician Hurls Structure and Disorder Into Century-Old Problem

December 15, 2021 — A new paper shows how to create longer disordered strings than mathematicians had thought possible, proving that a well-known recent conjecture is “spectacularly wrong.”### Mathematician Disproves 80-Year-Old Algebra Conjecture

April 12, 2021 — Inside the symmetries of a crystal shape, a postdoctoral researcher has unearthed a counterexample to a basic conjecture about multiplicative inverses.### Statistics Postdoc Tames Decades-Old Geometry Problem

March 1, 2021 — To the surprise of experts in the field, a postdoctoral statistician has solved one of the most important problems in high-dimensional convex geometry.### Computer Scientists Achieve ‘Crown Jewel’ of Cryptography

November 10, 2020 — A cryptographic master tool called indistinguishability obfuscation has for years seemed too good to be true. Three researchers have figured out that it can work.### Mathematicians Report New Discovery About the Dodecahedron

August 31, 2020 — Three mathematicians have resolved a fundamental question about straight paths on the 12-sided Platonic solid.### Landmark Math Proof Clears Hurdle in Top Erdős Conjecture

August 3, 2020 — Two mathematicians have proved the first leg of Paul Erdős’ all-time favorite problem about number patterns.### A Number Theorist Who Solves the Hardest Easy Problems

July 1, 2020 — In his rapid ascent to the top of his field, James Maynard has cut a path through simple-sounding questions about prime numbers that have stumped mathematicians for centuries.### In a Single Measure, Invariants Capture the Essence of Math Objects

June 2, 2020 — To distinguish between fundamentally different objects, mathematicians turn to invariants that encode the objects’ essential features.### Graduate Student Solves Decades-Old Conway Knot Problem

May 19, 2020 — It took Lisa Piccirillo less than a week to answer a long-standing question about a strange knot discovered over half a century ago by the legendary John Conway.### ‘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.### 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.### 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.

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.
