Final year PhD researcher at University of Bristol's Interactive AI CDT. I'm interested in how animals make and use internal maps of their environment.

In neurophysiology people often estimate "phase coherence", ie the trial-to-trial alignment of some brain signal (EEG/MEG/LFP) to some oscillation. This is hard using frequentist stats, so Sydney Dimmock, me & @conorjh developed a better Bayesian method: elifesciences.org/articles/84602
turns out brain representations of the world can 'drift' over days-weeks, even when behaviour is stable. The causes of this drift are unclear. Here we (i.e. Kipp Freud) find that reward and sharp-wave ripples correlate better with hippocampal drift that mere time or experience
