Michael Lacey was born on September 26,1959. Growing up, he probably didn’t imagine that he would do great things once grown up. After elementary, junior high, and high school, he went on to receive a Ph.D from University of Illionis-Urbana Champaign in 1987. For his theme, he focused on Banach Spaces, and went on to solve a problem related to the law of the iterated logarithm for empirical characteristic functions. To sum up, he became a mathematician and focused on various math topics such as probability, the ergodic theory, and harmonic analysis. His work experience includes a position at LSU, University of North Carolina-Chapel Hill, Indiana University, and Georgia Institute of Technology. At North Carolina, he and a man named Walter Philipp gave proof of the central limit theorem, thus contributing to the field of mathematics once again. At Indiana, he received the National Science Foundation postdoctoral Fellowship for his accomplishments and contributions not only to the university but to the subject as well. He also received the Salem Prize in 1996 for another problem solved. Following this, he would move on to GIT, where he received the Guggenheim Fellowship for joint work with Xiaochun Lin. The Simmons Foundation also recognized his work in the field. Lastly, he became a member in the American Mathematical Society. His dedication to math has helped him achieve a lot of things. Today, he still works at GIT as a tutor for phD students as well as doctorate students. He is also a director of training grants, and advises undergrad students who eventually go on to pursue doctorate degrees. Michael Lacey has contributed a lot to Mathematics, as well as to the other schools where he worked at, and for this we say thank you, because he has expanded our knowledge and opened the path for other people to continue contributing, just like he did.
