We’re excited to welcome Bien Group postdoc Louis Christie to the CBIOMES community.
HH: In summary, what are your research interests?
LC: I focus on data that lives in complex nonlinear spaces: how can we build estimation and inferential methods when we lose our usual intuitions about means and variances. My main tool for studying data in these spaces is symmetry, which generalises classical notions of sparsity from the lienar context into these non linear spaces. This work has applications in diverse scientific fields, including examining the behaviour of sunspots and in protein imaging tools such as Cryo-Electron Microscopy.
HH: What is your role in Jacob’s group? What are you going to be working on for CBIOMES?
LC: I will be working with Jacob on building statistical tools to solve new problems in oceanography. In particular, we’re looking at how to combine and compare data sources with a lot of structure (for example, flow cytometry imaging and phylogenetic information) to best make use of the available information.
HH: What is your educational background (BS, MS, PhD?)
LC: I completed a conjoint Bachelors of Arts and Bachelors of Science (Hons) at the University of Auckland, with majors in mathematics, statistics, physics, and economics. I then moved to the University of Cambridge to complete a Masters of Advanced Studies (MASt) with a focus in statistics, and then continued into a PhD in the Mathematics of Information supervised by Prof. Sir John Aston.
