You are never given a wish without also being given the power to make it true. You may have to work for it, however. Richard Bach, Illusions

Background

After six years in the field of Mechanical Engineering (Applied Mechanics, Bauman Moscow State Technical University, Russia) Elena joined the Signal Processing Group of the Cambridge University Engineering Department, where she completed her MPhil and, later, PhD degree ( St. John's College). She then held a Junior Research Fellowship and later a Fellowship at Homerton College, University of Cambridge, and was involved in real-world research development and first technology deployments with several Cambridge spin-offs. She is now a College Lecturer, Fellow, and Director of Studies in Engineering at Christ's College, University of Cambridge.

Research Interests

Her interests include Bayesian statistical inference, probabilistic data modelling, simulation-based methods for scientific computing, such as, Sequential Monte Carlo and Markov chain Monte Carlo methods, and applications in the areas of digital communication, signal and image processing, data mining, machine learning and pattern recognition, engineering for life sciences, finances and etc.
