Research Interests Professor Whittenburg's research involves application of modern computing methods such as distributed and parallel computing to problems of interest to chemists. Some of these areas include probabilistic methods, such as Bayesian analysis, ab initio calculations, molecular dynamics and micromagnetic simulations. Dr. Whittenburg and his group are applying a probabilistic theory termed Bayesian analysis to analyze the experimental data from a wide-range of experiments, including NMR, ICP and XAFS. The Bayesian method promises a higher resolution and better signal-to-noise response than conventional Fourier or least-squares analysis of experimental data. Bayesian analysis is the preferred method of data analysis. Recent interests are in the modelling of magnetic storage devices, such as disks and memory, using micromagnetics simulations. Micromanetics allows us to compute the magnetic properties of materials based on their shape and composition. These simulations are crucial in the understanding and development of current very high density recording technology. Below is the result of such a simulation. Dr. Whittenburg is a member of the Advanced Materials Research Institute (AMRI), a multidisciplinary materials research laboratory that combines the interests of academic, government and industrial scientists working on collaborative research.
