About

Overview

Dr Yarrow began his research career as a Research Assistant working at the MRC Human Movement and Balance Unit in Queen Square, London.

He subsequently completed a PhD with John Rothwell at the Institute of Neurology, UCL. Dr Yarrow continued to work at the ION during a four year period of postdoctoral research, which was also carried out in collaboration with Patrick Haggard at the Institute of Cognitive Neuroscience, UCL.

He joined City University London in October 2006 (now City St Georges) and is a Reader in the Department of Psychology & Neuroscience.

Research

Dr Yarrow's research interests include multisensory perception (particularly temporal perception), attention, decision making, and action. PhD students in Kielan's lab have investigated topics such as the automatic priming of the motor system by graspable objects, the way truthful responses leak into primary motor cortex during deception, how evidence for rapid decisions accumulates in the brain, and the cognitive basis of time perception.

Dr Yarrow has been the recipient of several large grants at City St. Georges. The most recent is an ESRC Project Grant running from 2025-2028 (with co-investigators Elliot Freeman, also at City, and Derek Arnold, at UQ): “Testing brain-time theoretic links between neural and behavioural estimates of the fidelity of human temporal perception.” (FEC £437,069). Before that, the Leverhulme Trust awarded him a three-year Research Project Grant (£216,306) with co-investigators Tina Forster (also at City’s Department of Psychology) and Sven Bestmann (UCL). The project was entitled "Novel neurometric measures to discriminate models of speeded decision making" and ran until November 2017. Overlapping that (with co-investigator Joshua Solomon, from City's Department of Optometry and Visual Science) was a BBSRC funded project, "New methodologies to explain and improve the expert anticipatory advantage in sports decision making" (2013-2016, FEC £469,644).

Dr Yarrow has also been a partner investigator on two ARC (Australian Research Council) Discovery Grants (with chief investigator Derek Arnold, University of Queensland), one entitled "Distorted Time Perceptions: Altered neural coding or decisional criteria?" (2014-2016, AU$163,000) and one entitled "Why does time seem to drag or fly?” (2018-2020, AU$199,000).

Kielan runs the transcranial magnetic stimulation lab, where a powerful magnet is used to interfere with the brain's activity.
