    My research interests concern the application of polynomial homotopy continuation to scientific and engineering problems . The methodology involves the following fields: Computational Algebraic Geometry, Symbolic-Numeric Computation, Combinatorial and Polyhedral Methods, Mathematical Software and Applications, and Supercomputing. See the poster about numerical algebraic geometry; and the poster about PHCpack and phcpy; and the poster presented at the SciPy 2019 conference.
    Updated Wednesday 30 June 2021 with PHCpack 2.4.85.
    Updated Saturday 27 February 2021, with phcpy 1.1.1.
