Kinematics is the study of motion of objects regardless of the causes of this motion. (Not to be confused with Kinetics.) There are close connections between the study of motion in robotics and in molecular biology. However, structural bioinformatics raises new and challenging computational kinematic problems due to the large number of degrees of freedom typically involved. The goal of the seminar is to get the audience acquainted with kinematic issues (problems and some solutions) in structural bioinformatics. We will review techniques (heuristics as well as exact methods) and applications.

The seminar is primarily geared towards students with significant computational background. (It does not assume prior knowledge in molecular biology, but requires willingness to pick up the basics and relevant terminology.) This said, the first part of the seminar (inverse kinematics, loop closure) relies mainly on not-too-complex math. The second and shorter part (dynamic maintenance of kinematic structures) assumes familiarity with data structures and algorithms at the senior(last-year)-undergrad level.


The seminar will start with two introductory meetings, followed in subsequent weeks by student presentations. Here's the program, revised on 10/11/04.
