    Title: Bayesian Analysis of Raman Spectroscopy


    Raman spectroscopy is a measurement technique that can be used to quantify the chemical composition of a sample. For example, the amount of alcohol in a glass of beer, or the presence of inflammatory biomarkers in blood. The “Perseverance” rover is currently using Raman spectroscopy to search for traces of ancient life on Mars. The main difficulties in analysing this data are due to multiple, overlapping peaks and a curved baseline. In this talk, I will describe a statistical model for joint estimation of the peaks and baseline. The locations of the peaks depend on the structure of the molecule, so it is often possible to obtain informative, Bayesian priors using computational chemistry. In the absence of such prior information, we can model the peak locations as a point process. We fit this model using a sequential Monte Carlo (SMC) algorithm, which we have implemented in the R package “serrsBayes.”

    This is joint work with Lassi Roininen, Teemu Härkönen, Emma Hannula & Erik Vartiainen (LUT, Finland), Jake Carson (Warwick, UK), Mark Girolami (Cambridge, UK), Kirsten Gracie, Karen Faulds & Duncan Graham (Strathclyde, UK).

    Matt completed his doctorate at QUT in 2015, under the supervision of Kerrie Mengersen and Fiona Harden. He was then appointed as a postdoctoral research fellow in the Department of Statistics at the University of Warwick, UK, first under the supervision of Mark Girolami, before joining the “i-Like” project under the supervision of David Firth. He joined the University of Wollongong in 2018 with a continuing lectureship in statistical science. In 2021, he was awarded the title of Docent in Computational Statistics at Lappeenranta University of Technology (LUT), Finland. Matt’s research interests include MCMC and SMC algorithms for intractable likelihoods and inverse problems in spectroscopy, satellite remote sensing, and data-centric engineering.
