Alex Barnett is an applied mathematician and numerical analyst. He is a Senior Research Scientist, and Group Leader for Numerical Analysis, at the Center for Computational Mathematics at the Flatiron Institute in New York City. After a Ph.D in physics from Harvard, he did postdoctoral work in radiology at Massachusetts General Hospital and as a Courant Instructor at New York University. He then served on the mathematics faculty at Dartmouth College for 12 years, reaching the rank of full professor, and creating several new courses on topics such as the mathematics of music and sound. His main research areas are scientific computing, partial differential equations (including wave scattering and viscous fluid flow), boundary integral equations, fast algorithms, signal processing, statistics, imaging, inverse problems, biomathematics, and quantum chaos. In several of these areas he has released popular software implementations. He has authored or coauthored over 70 academic articles. His awards include several NSF grants, Dartmouth's Karen E. Wetterhahn Memorial Award for Distinguished Creative or Scholarly Achievement, and 1st prize in the 1990 International Physics Olympiad.
