Research Areas

Numerical Algebraic Geometry
Motivated by realistic problems, a trend from pure symbolic computation to
symbolic-numerical computation has occurred. I am mainly concerned with
adapting the concepts in exact polynomial algebra to the approximate case and
developing numerical stable methods to obtain structural information characterizing
polynomial ideals, e.g. my work on numerical factorization of polynomials
and its geometric foundations. Recently, I am interested with real algebraic
geometry based on homotopy methods and the associated sensitivity analysis.
