I use psychophysical methods to investigate how temporal expectations bias complex decision making and whether timing theories generalise under experimental tasks that are representative of complex everyday decisions. I do this via sound lateralization, complex averaging/valuation experiments, decision weight analysis and computational modelling. By investigating the interdependence between temporal expectations and complex decision making I aim to build a predictive framework on which to quantitively map out underlying cognitive processes. This can then be applied to the field of human-machine interface design with the aim of helping people make more accurate classification decisions. My PhD is supervised by Professors Ian Cross and Sarah Hawkins and has so far been examined by neuroscientist Dr Benedetto De Martino and senior lecturer in sound processing Dr Marcus Pearce. The research was fully funded by a research council studentship received in 2013.

In addition to my PhD, I gained an MPhil from the CMS between 2010-2011 where I investigated the cross-modal effects of temporal expectation on attention which involved running audio-visual experiments. The work showed that acoustically induced temporal expectations were accompanied by fluctuations in visual selective attention, highlighting the potential dangers of listening to loud beat based music whilst driving. Prior to Cambridge, I graduated with a first class degree from Birmingham Conservatoire.

In addition to my time in Cambridge I received an offer to study a PhD at the department of physiology and neuroscience at the University of Oxford under the supervision of Professors Kia Nobre and Jan Schnupp in 2012. I also have a strong business analytic background having worked as a financial analyst for Visa Europe, a technology startup in Poland and currently at AstraZeneca in Cambridge. I sit on the advisory board of a UK based research charity called Reverse Rett who fund scientific research into Rett Syndrome and related MECP2 disorders and co-lead the Cambridge University algorithmic trading society (CUATS).
