The name of an important United States mathematician is Michael Lacey, and the man has worked at Georgia Tech University since 1996. He has taught lots of graduate and undergraduate students combined, and to date has more than 10 graduate students under his wing. He has been awarded the MCTP and VIGRE awards from the NSF, or National Science Foundation. In addition to this, Michael Lacey has been awarded many achievements including the Guggenheim and Simons Foundation Awards. Basically what that means is that his work in mathematics has been respected by his peers for its great excellence. The kinds of math which has been so widely revered across the space of math in America includes ergodic theory, harmonic analysis, probability, the central limit theorem, and banach spaces. 2004 was the year in which Michael Lacey received the Guggenheim Foundation Award, and this occurred right after his time at UNC, also known as the University of North Carolina at Chapel Hill. (UNC is a very highly respected institution, nationally).
Until 1996, which was about seven years, Michael Lacey was indeed spending time at Indiana University for a postdoctoral fellowship. In Indiana, Michael Lacey began his mathematical work on bilinear Hilbert transforms. Michael and his friend Christophe Thiele together tackled the mathematical beast which is the bilinear Hilbert transform, and which has to do with sines and cosines. Because of their work together at Indiana, they were both awarded the Salem Prize, which back in the day was worth 5000 French Francs. And the Guggenheim award was actually awarded to Michael in 2004 based on his work together with Xiaochun Li. His first doctoral role was at Louisiana State University, which is located in Baton Rouge, Louisiana; for more information on Michael Lacey, check his math Alliance website here.
