Maria Chait

Maria Chait

Head of Lab

I am a Reader (Associate Professor) 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, USA under the supervision of Jonathan Simon and David Poeppel. My undergraduate 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  and the Dual Masters in Brain and Mind Sciences. I am also a member of the UCL Neuroscience domain steering group.


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.


Ulrich Pomper

Research Associate

Ulrich Mag Pomper

I’m a post-doctoral researcher interested in auditory attention and the underlying oscillatory neural mechanisms. Part of my work focuses on finding electrophysiological markers of auditory attention that can be used to steer hearing aids. Also, I’m fascinated by the question of how the brain state prior to an event shapes the processing and perception of that event (e.g. via expectations or predictions).

I did my Diploma in Psychology, at the University of Vienna. After that, I went to do a PhD with Prof. Daniel Senkowski, first at the University Medical Center Eppendorf, Hamburg (Department of Prof. Andreas Engel) and later at the Charité, Berlin.

Apart from attention, my research previously concentrated on multisensory integration between the visual, auditory and somatosensory domains, and involves both EEG and behavioural measures.


Daniel Bates

Daniel Bates

Research Assistant + PhD Student

I am interested in how we are able to interact with (and build an understanding of) the world through our auditory and visual experiences.

My research utilises psychophysics and brain imaging to understand what a listener can attend to, how selective attention is affected by different sound contexts and what brain mechanisms may be involved in this process. This work is part of a European Commission funded project aiming to understand how listener’s attentional state can be ‘read-out’ in real time to steer a hearing aid. 

I have a BSc in Psychology from the University of Liverpool (2013) and MSc in Neuroscience, Language and Communication from UCL (2014).


Katharine Molloy

Kate 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.


Sijia Zhao

Sijia Zhao

PhD Student

My research focuses on understanding how sensitivity to acoustic patterning arises in the auditory cortex and the degree to which regularity attracts auditory attention, by utilising functional brain imaging techniques (fMRI, EEG, MEG) and psychophysics.

I have BSc Neuroscience and MSc Computer Science degrees, both from UCL.

I am broadly interested in the interdisciplinary areas of auditory neuroscience and artificial intelligence.


Rosy Southwell

Rosy Southwell

PhD Student

I am interested in the sensitivity of the human brain to patterns and regularity in sounds, and the effect of attention in recognising these patterns. I use psychophysics, EEG and MEG. 

Before joining the Ear Institute, I completed short projects in two other UCL research groups: with Sven Bestmann on the pharmacology of signalling uncertainty, and with Dimitris Pinotsis on modelling neural dynamics in visual cortex.

I have a BA (2012) in Natural Sciences and an MSc (2013) in Systems Biology from Cambridge University. I have also worked as a Research Assistant in Dr. Bob Carlyon's group at the Cognition and Brain Sciences unit in Cambridge, developing psychophysics tasks for assessing auditory perception in cochlear implant users.


Mathilde Le Gal de Kerangal

PhD Student

Mathilde

My research focuses on evaluating hearing impaired listeners’ sensitivity to changes in multi-object acoustic scenes that model the complex acoustic environment encountered during every day listening (e.g a crowded street or a busy restaurant). My project involves EEG and behavioural experiments.

I did a Bachelor degree in Mechanical engineering (UPMC, Paris), following Musicology courses in parallel (La Sorbonne, Paris). I obtained a MSc degree in Acoustics and signal processing (IRCAM, Paris) before joining the Ear Institute.

I am funded by an Action on Hearing Loss PhD stundeship.

Thesis title: "Auditory Pattern Detection"

Nicolas Barascud

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 joined the UCL Ear Institute as a PhD student in 2011 and moved on to a Post Doc position (co-supervised with Prof. Tim Griffiths) 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).


Lefkothea Vasiliki Andreou- PhD 2016

Lefkothea

Thesis title: "Sensitivity to temporal structure supports auditory scene analysis - a Psychophysics and MEG investigation"

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.
