Overview

Tom DeLillo received his PhD from the Courant Institute, NYU, in 1985. He held postdoc and visiting positions at Exxon Research and Engineering, UNC Chapel Hill, and Duke University before coming to 成人头条 State in 1988.

Tom DeLillo's research is in the numerical and theoretical study of conformal maps and in the development of computational methods for inverse problems in acoustics and gravimetry. He has developed several new methods, based on fast Fourier analysis, for computing conformal maps of simply and multiply connected domains in the complex plane, studied the ill-conditioning of those methods, and applied the methods to problems in fluid flow and plane stress and strain. He has extended the well-known Schwarz-Christoffel formula to multiply connected domains and implemented the formula numerically. He has also worked on inverse problems in acoustics, developing efficient computational methods to reconstruct boundary vibrations from interior pressure measurements. These methods can be applied to help locate sources of noise in aircraft and automobile cabins. In addition, Dr. DeLillo is interested in the mathematics of elementary particles physics and quantum field theory and he occasionally teaches courses on these topics. Recently he has been developing teaching material for the department's new programs in the mathematical foundations of data analytics.
