Professor Davi Geiger is a visiting assistant professor at the Courant Institute, New York University. He received the Ph.D. from MIT in Physics working also at the Artificial Intelligence Laboratory. Dr. Geiger has held a visiting position at the Isaac Newton Institute for Mathematics and Applications, in Cambridge, England. Dr. Geiger has also worked in Medical Imaging at Siemens Corporate Research, NJ.

Dr. Geiger's research interest are in computer vision as a visual information science and its applications. In particular, he has been interested on using statistical and robust techniques to detect reliable features for recognition schemes. He has been interested on techniques, methods, and models capable of efficiently combining local features with global ones from a Bayesian framework, e.g. dynamic programming for hidden Markov models and generalizations for Markov random fields. He has succesfully applied these methods on medical and biochemistry imaging, for the detection and analysis (i) of the evolution of the heart, from MRI images (now a product of the Siemens MRI machines) and (ii) of the DNA molecules from miscroscopic imaging (now being used for the GENOME project at the W. M. Keck Laboratory for Biomolecular Imaging, Dept. of Chemistry, NYU.)

Dr. Geiger was the keynote speaker of the 1993, 10th Israeli Symposium on Aritificial Intelligence, Computer Vision and Neural Neworks, and invited speaker on the 1992 SIAM Conference on Linear Algebra and its Applications.
