Research Interests Jeffrey Meier
Broadly, I am interested in knot theory, knotted surfaces, and the topology of 3manifolds and 4manifolds. In particular, I have a great interest in trisections of 4manifolds; 4dimensional knot theory, including fibered ribbon 2knots, knotted Klein bottles and projective planes, surgery operations, and bridge trisections; various aspects of knot concordance, including doubly slice knots, fibered ribbon knots, cabled slice knots, and applications of knot homology theories; and Dehn surgery, especially exceptional surgery and Seifert fibered surgery.
