Alex Barnett is an applied mathematician and numerical analyst. He is currently Group Leader for Numerical Analysis at the Center for Computational Mathematics at the Flatiron Institute in New York City. His Ph.D in physics was from Harvard, and his postdoctoral work was in radiology at Massachusetts General Hospital, then as a Courant Instructor at New York University. He 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. His research areas include scientific computing, partial differential equations (including wave scattering and viscous fluid flow), boundary integral equations, fast algorithms, signal processing, statistics, imaging, inverse problems, eigenvalues and quantum chaos, and neuroscience. In several of these areas he has collaborated on popular software implementations. 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.
