Aubrey Kelly - Evolutionarily Conserved Mechanisms of Sociality

There is an extraordinary amount of variation in social behavior within and across species. However, when phenotypic convergence in behavior (e.g., sociality) is observed, it begs the question as to…

Thomas Rothvoss - Linear Size Sparsifier and the Geometry of the Operator Norm Ball

The Matrix Spencer Conjecture asks whether given n symmetric matrices in ℝn×n with eigenvalues in [−1,1] one can always find signs so that their signed sum has singular values bounded by…

Steven A. Sloan - Using Human Brain Organoids to Unveil Neuron-Glial Interactions During Development

Glia are the most abundant cell types in the mammalian nervous system. They are integral to normal brain physiology, yet we still understand very little about what functions they perform, how they…

Yin Tat Lee - Solving Linear Programs in the Current Matrix Multiplication Time

We show how to solve linear programs with accuracy epsilon in time n^{omega+o(1)} log(1/epsilon) where omega~2.3728639 is the current matrix multiplication constant. This hits a natural barrier of…
