Michael Lacey Has Blazed a Bright Trail Across the World of Numbers

Michael Lacey in one of America’s premier mathematicians and a world-recognized scholar who has been lauded for his work in some of the most challenging problems facing the science of numbers today.

Lacey was awarded a doctorate degree in 1987 for his work in an important area of math known as Banach spaces, named for famed Polish mathematician Stefan Banach. This area or inquiry concerns what mathematicians call functional analysis, and specifically, that which pertain to vector spaces. Read more: Michael Lacey | Mathalliance

Michael Lacey’s innovative work solving a difficult problem relating to the law of iterated logarithms as they play out in empirical characteristic functions is what earned him a Ph.D.

It was a an impressive achievement for the young numbers cruncher. He had managed to solve a vexing dilemma in math that had eluded many other world-renowned mathematicians. But Lacey was only getting started.

After earning his doctorate, the newly minted “Dr. Lacey” was offered a position at Louisiana State University, and then found a more permanent home at the University of North Carolina, Chapel Hill. There he continued to blaze trails while working with one of the world’s most important mathematician, Walter Philipp, an Austrian genius who specialized in probability theory and the theory of numbers.

Working with Philipp, Michael Lacey brought out a proof of the “almost sure” central limit theorem. Then Lacey moved on to Indiana University where he worked on Hilbert transform after receiving a National Science Foundation Postdoctoral Fellowship.

Lacey, cooperating with Christoph Thiele, solved the Hilbert transform. For this he was awarded the prestigious Salem prize, one of math’s highest honors named for Greek mathematician Raphaël Salem, the man who developed “Salem Numbers” – numbers that are highly significant to what is known as Diophantine approximation and harmonic analysis.

In 1996 Michael Lacey joined the Georgia Institute of Technology. While there, he received a Guggenheim Fellowship for new work he began along with Dr. Xiaochun Li.

In 2012 Dr. Michael Lacey was named a fellow with the American Mathematical Society, solidifying his stature among the most important math scholars not just in America, but the world.
