Maria Chait

Maria Chait

Head of Lab

I am a Reader in auditory cognitive neuroscience at the Ear Institute, UCL. I moved to UCL in 2007, as a Marie Curie research fellow, following a short post-doc at Equipe Audition in Ecole normale supérieure, Paris.

My PhD research (2006) was conducted at the Neuroscience and Cognitive Science program, university of Maryland College Park under the supervision of Jonathan Simon and David Poeppel. My bachelor’s background is in Computer Science, Economics, and East Asian Studies.

Among my UCL responsibilities is the co-direction of the Sensory Systems, Technologies and Therapies (SenSyT) PhD program.


Ediz Sohoglu

Ed Sohoglu

Research Associate

I'm a Post-Doctoral researcher working on a BBSRC-funded project investigating auditory change detection (with Maria Chait). Prior to this, I completed a PhD in Cognitive Neuroscience with Matt Davis at the MRC Cognition and Brain Sciences Unit in Cambridge; an MSc in Music Technology at the University of York; and a BSc in Neuroscience at the University of Sussex.

I aim to understand how the auditory system achieves the task of processing the many sounds we encounter in everyday listening, such as music and speech. A recurring question in my research is how and in what conditions is the auditory system able to successfully process sound in "challenging" listening situations, such as when multiple sounds are present or when sensory information is highly degraded. Ultimately, I hope this research will lead to improved perceptual outcomes in the hearing impaired.


Nicolas Barascud

Nicolas Barascud

Research Associate; Co Supervised with Prof. Tim Griffiths

I am generally interested by how behaviourally relevant information is derived from sound. My PhD work focused on understanding sensitivity to patterns in sound sequences. I am currently studying working memory processes.

I joined the UCL Ear Institute as a PhD student in 2011 and moved on to my current Post Doc position in end of 2014. I have an MSc in Acoustics and Signal Processing (IRCAM, Paris), and an MSc in Cognitive Neuroscience (Université Pierre et Marie Curie, Paris). I also have a Magistère in Theoretical Physics (Université Paris Sud 11, Orsay).

PhD Student

I study the effect of temporal regularities on the analysis of auditory scenes and the neural bases of rhythm perception. My methodology combines psychophysics and brain imaging (MEG) in normal listeners.  A specific challenge and methodological goal is to design behavioural paradigms, which are not dependent on purely subjective reports, to measure listener’s perceptual organization.

I have a BSc in  Biochemistry (2002) and an MSc in Biotechnology (2005), both from the School of Medicine, University of Ioannina, Greece. I also have a BA in English Language and Literature (2008) from the National and Kapodistrian University of Athens.


Katharine Molloy

PhD Student; Co Supervised with Prof. Nilli Lavie

My research focuses on how well we perceive sounds when our attention is engaged in a visual task. Our hearing system is often regarded as an early warning system which reacts to unexpected sounds even when we are busy elsewhere. However, it has recently been shown that very demanding visual tasks can cause deficits in our auditory perception. I am investigating which auditory processes are susceptible to this interference, using psychophysics to determine when behaviour is affected, and MEG to measure brain responses.

I studied Maths at Cambridge for my undergrad degree, followed by an MSc in Experimental Psychology at Sussex. I then worked as a Research Assistant for the MRC Institute of Hearing Research for three years, before starting at UCL. I am jointly supervised by Nilli Lavie at the Institute of Cognitive Neuroscience, and Maria Chait at the Ear Institute.


Theofilos Petsas

Theofilos Petsas

PhD Student

I joined the Ear Institute as a PhD student at the beginning of the academic year in 2014. My scientific background is based on acoustic engineering and signal processing. My project at UCL investigates auditory salience using non-invasive psychophysical experiments and neuroimaging techniques.

I have a BSc in Music Technology (University of York) and an MSc in Sound & Vibration (Institute of Sound and Vibration Research, University of Southampton). Apart from my scientific interests in the auditory neuroscience and the broader field of sound, I am also active as a music artist (q-funktion).

I am funded by an IMPACT studentship, in partnership with NTT, Japan


Rosy Southwell

Rosy Southwell

PhD Student

I am a first-year student on the 4-year PhD programme at the Institute of Neurology.

For my first lab rotation I am working in the Chait Lab, looking at MEG data which show how the brain responds to changes in sound regularity.

Before joining the Ear Institute, I worked as a Research Assistant in Bob Carlyon's group at the Cognition and Brain Sciences unit in Cambridge, developing psychophysics tasks for assessing auditory perception in cochlear implant users.

I have a BA (2012) in Natural Sciences and an MSc (2013) in Systems Biology from Cambridge University.


Alumni 2013/14

Samuel Picard

Samuel Picard

MSc Student; co-supervised with Prof. Tim Griffiths

I’m an MSc student in the Dual Master’s in Brain & Mind Sciences program, currently in my first year at UCL.

I am broadly interested in how temporal information is represented in auditory perception and motor control.

My Research Project focuses on the effects of temporal coherence on auditory figure-ground segregation. Using MEG and psychophysics, I aim to elucidate some of the mechanisms by which the brain detects auditory “objects” in complex acoustic scenes.

I have a BSc in Cognitive Neuroscience (2011) from University College Utrecht, the Netherlands.

Before coming to UCL, I spent two years in Prof. Chris De Zeeuw’s lab at the Netherlands Institute for Neuroscience (Amsterdam), working with cerebellar patients, and at the Erasmus MC (Rotterdam), working on in vivo electrophysiology in the mouse cerebellum.
