I'm a research fellow in the AlphaLab at Birkbeck. My research focuses on the neural basis of communication.
+ perceptual weighting strategies
+ functional connectivity and compensatory processes
+ representation of words and concepts
+ clinical conditions affecting communication and social interaction

A poster summarizing recent published work on perceptual weighting strategies for speech and music was presented at the SNL2020 meeting.
Some individuals tend to perceive repeated spoken phrases as song (the "song illusion"). Here we show that song-perceivers have better musical perception skills in general, which suggests that the "song illusion" results from detecting latent musical patterns in speech.

Participants categorized instances of a two-word phrase pronounced with typical covariation of fundamental frequency (F0) and duration, and in the context of an artificial ‘accent’ in which F0 and duration covaried atypically. We find that prosodic categories (much like segmental speech categories!) are cued by multiple acoustic dimensions whose perceptual weights dynamically adapt to local regularities in speech input.

Here we show that native speakers of Mandarin—a language where pitch is very important—rely heavily on pitch to process other kinds of sounds: They weight pitch highly when processing (second language) English speech, when processing music, and they even struggle to ignore pitch when it's task irrelevant. The results demonstrate a new way that characteristics of one's native language influence perception.

Individuals with congenital amusia, who have unreliable pitch processing, show decreased functional connectivity between right auditory and left language-related cortex during speech perception, demonstrating a neural basis for compensatory dimensional weighting.

Perception of speech and music involves integration of pitch, duration and amplitude cues. Individuals tend to prioritize these dimensions using individualized strategies. Here we show that these strategies arise from perceptual abilities.

Nature Reviews Neuroscience
In this opinion article we discuss how temporal response properties of neurons in auditory cortex may give rise to the distinct neuroanatomical pathways for processing 'what' a sound is and 'where' and 'how' it was produced.

We use a novel fMRI paradigm to examine neural activity during naturalistic, real-time face-to-face conversations and resting state in autism. We also discuss the study in our recent review.

We show that speaking together (as in group chants) recruits right hemisphere regions outside the classic speech network and blurs the boundary between the self and the other.

We review the autism resting state fMRI literature, highlight the potential role of the thalamus and striatum in autism, and emphasize the need for studies that directly compare scanning during multiple cognitive states in addition to the resting-state.

We outline the exciting ways virtual reality can be used to study language, as well as the pitfalls.

We used fMRI to show that whether or not someone is looking at your when they're talking (their gaze direction) affects brain activity in left hemisphere areas that process speech.

By measuring frequency following responses with EEG, we show that difficulty learning a second language in adulthood may be partly due to auditory perception problems.
Omote, A., Jasmin, K., Tierney, A. Cortex
We find, using 7T fMRI, that reading sentences with social-emotional words activates regions across the 'social brain' network. Reading sentences with inanimate object words activates object/scene recognition regions. We suggest it is important to take semantic content into account when studying reading.

We show that, through associations between left-right space and emotion, the hands we use to type words on a keyboard may slowly shape the emotional associations of those words.

English uses front-back spatial metaphors to talk about time. Do English speakers think about this time way? Here we use evidence from hand gestures to show that English speakers use the front-back axis to gesture about time deliberately, but prefer a left-right axis when gesturing spontaneously.

Speakers associate positive messages more strongly with dominant hand gestures and negative messages with non-dominant hand gestures, revealing a hidden link between action and emotion.
