I have lived in California since 1995 after emigrating from St. Petersburg, Russia. I have worked for various Silicon Valley companies as a computer scientist. My basic education is applied mathematics. After graduation, I took courses at the Faculty of Mechanics and Mathematics of St. Petersburg University in pure mathematics: algebra, topology and functional analysis. Later, I defended my Ph.D. thesis in computer science. My main passion is the development of algorithms in the field of graph theory, image analysis and 3D graphics. In my professional work, non-trivial tasks often arose for which there was no ready-made answer. My math lessons helped me find the solution. For example, my PhD thesis was related to the application of graph theory to the synthesis of integrated circuits. In the development of algorithms, I used the methods of embedding graphs in two-dimensional manifolds and the theory of lattices, which I mastered while studying algebra and topology. Later, my interests shifted to image analysis, which I did while working at the University of California, San Francisco. My research there was devoted to computer analysis of MRI images morphology. In the field of image processing, I also dealt with correcting and analyzing document images for start-up company ScanR Inc. I developed document content recognition algorithms using active contour methods and spectral analysis of two-dimensional signals. Working for NASA Ames Research Center, one of the my tasks was the lands classification of the earth's surface from the results of satellite images. I got my experience with 3D graphics at Web Scope Inc, working on the creation of a multi-user network tools for manipulating mechanical models. Finally, I worked with data analysis methods and recommender systems at eBay computing lab. In recent years, I have been working on independent projects in the field of computer graphics: landscape generation for VR and graph theory : approximate methods for solving NP complete problems, in particular traveling salesman problem. I like programming. My latest hobbies: Haskell and Javascript plus BabylonJS My non-work hobbies include fitness, martial arts, science fiction, VR games and philosophy of mind.
