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 served on the mathematics faculty at Dartmouth College for 12 years, becoming a full professor, and creating several new courses on topics such as the math of music and sound. His research includes numerical partial differential equations (wave scattering, Stokes flow, and high-frequency eigenvalues), integral equations, fast algorithms, signal processing, statistics, imaging, inverse problems, quantum physics and biomathematics. He has authored or coauthored over 70 articles and two books, and developed popular scientific software libraries. 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.
