The course will teach you the basic mathematics, algorithms, techniques and tools of imaging, geometric and physiological modeling and visualization with applications in the biomedical sciences and engineering. Bio-medical modeling (or Biomodeling) and visualization has roots in medical illustration and communication for the health sciences, with branches of application to mathematical modeling and computer simulation of artificial life. In this course we shall emphasize computational image processing, harmonic analysis, computational topology, computational geometry (algebraic and differential), group theory, polynomial spline approximations, computer graphics, data analysis, together with aesthetic choices involved in producing effective scientific animations. The emphasis shall be on spatial realism, and the programmatic use of multi-scale modeling, analysis and visualization to quantitatively depict "how things work" at the molecular, and cellular scales.
Exercises on image processing, geometric and physiological modeling analysis and visualization at multiple scales, shall be drawn from virology (viral envelopes, capsids, proteins, nucleic acids), and neurology (brain, hippocampus, neuropil, axons, dendrites, glial cells, ion-channels, neurotransmitters), and their interactions (molecular energetics and force fields, molecular flexibility, synaptic transmission, synaptic spillover).
