Michael Lacey is a prominent American mathematician. He is well-known for contributions in several areas of mathematics, mainly concerning probability and statistics.
His full name is Michael Thoreau Lacey and he was born on September 26, 1959. He attended the University of Illinois at its Urbana-Champaign campus, where he received his doctorate in 1987. He worked under Walter Philipp, with whom he would continue to work in later years.
His thesis dealt with Banach spaces, which are complete normed vector spaces, and found a solution for an issue related to the law of the iterated logarithm as applied to empirical characteristic functions. Read more: Michael Lacey | GAtech and Michael Lacey | Wikipedia
Michael Lacey would go on to work at Louisiana State University and then the University of North Carolina after receiving his doctorate. It was while at the latter position that he and his old teacher, Walter Philipp, came up with a proof on central limit theorem (which states that independent random variables will often create a normal distribution, even if they are not normally distributed themselves).
In 1989 Michael Lacey moved to Indiana University, where he would remain until 1996; after that he went to the Georgia Institute of Technology, where he still works as a professor of mathematics today.
He has continued to study probability, as well as ergodic theory (which deals with dynamical systems that have an invariant measure and similar problems) and harmonic analysis (which focuses on representation of signals and function as the superposition of basic waves).

Michael Lacey has several other achievements to his name. He was awarded a National Science Foundation Postdoctoral Fellowship and used that time to study the Hilbert transform; he and Christoph Thiele managed to solve a conjecture that Alberto Calderón made about that problem, for which they won the prestigious Salem Prize. He also won a Guggenheim Fellowship in 2004 for his work with Xiaochun Li and became a fellow at the American Mathematical Society in 2012.
All of these endeavors make Michael Lacey one of the premiere mathematicians living and working in the United States today.
