CV

**Education:**

Ph.D., University of Texas

**Academic Interests and Research:**

Dr. Morgan's research interest is numerical analysis, more specifically large linear equations and eigenvalue problems. Some matrices are large enough and scary enough, computationally speaking, to be called Monster Matrices . See Personal Webpage for more info.

**Selected Publications:**

"Two-grid and Multiple-grid Arnoldi for Eigenvalues," *SIAM Journal on Scientific Computing*, 40 (2018), pp. A3470--A3494 (with Zhao Yang).

"Weighted Inner Products for GMRES and GMRES-DR", *SIAM Journal on Scientific Computing,* 39 (2017), pp. S610–S632 (with Mark Embree and Huy Nguyen).

"GMRES with deflated restarting," *SIAM J. Sci. Comput. 24* (2002), 20-37.

"On restarting the Arnoldi method for large nonsymmetric eigenvalue problems," *Math. Comp. 65* (1996), 1213-1230.

"A restarted GMRES method augmented with eigenvectors," *SIAM J. Matrix Anal. Appl. 16* (1995), 1154-1171.

"Computing interior eigenvalues of large matrices," *Linear Algebra Appl. 154/156* (1991), 289-309.

"Generalizations of Davidson's method for computing eigenvalues of sparse symmetric matrices,"* SIAM J. Sci. Statist. Comput. 7* (1986), 817-825, (with David S. Scott).
