Abstract: We employ topological/knot invariants to study knots and their frequency of occurrence in compact conformations on a lattice and in proteins. We also study the typical size of fragments or pieces of the compact conformation and show that the fragments for trivial knots are consistently smaller than those of other knots.

Speaker Bio: Rhonald Lua received his BS in Physics from the Ateneo de Manila University, Philippines. After a short stint as a software developer, he entered graduate school at the University of Minnesota and expects to receive his PhD in Physics in the Fall of 2005.
