I am a third-year mathematics graduate student at the University of California, Berkeley.

I graduated with a B.S. in Applied and Computational Mathematics from the California Institute of Technology.

My general mathematical interests are in applications of functional analysis, numerical analysis, harmonic analysis, partial differential equations, and dynamical systems to the sciences.

comment Is there a faster way to calculate a pseudo-inverse of a matrix than using SVD that is as numerically stable as with SVD?
Good to know. But note that in QR factorization is only going to work if $A$ has full rank.
