Linear Algebra
Linear algebra, matrix analysis, especially the theory of nonnegative matrices and their generalizations. Particular interests include the numerical range; graphs associated with matrices; matrix patterns over rings and finite fields; numerical linear algebra; applications in dynamical systems, data analysis and machine learning.
