Professor Bruce Levell's research interest is in sedimentary basins. Working with reflection seismic data in basins around the world has given him an appreciation of the extent the sedimentary record can be understood as a consequence of large scale basin evolution. He is particularly interested on how the preserved portions of the geological record represent the full sequence of geological events. The sedimentary record is neither a continuous and compete archive of events that can be read as a time series, nor so riddled with gaps that it is uninterpretable. Which raises the question as to how its biases can be understood and predicted.
