A PhD candidate studying Clinical Linguistics at the Clinical Audiology, Speech and Language Research Centre at Queen Margaret University, Edinburgh. After completing a BA honours in Psychology, I developed an interest in linguistics and chose to complete my Masters in Linguistics from Utrecht University, Netherlands. My Masters project focused on investigating speech rhythm in a motor speech disorder called dysarthria. I took further interest in dysarthria and am currently trying to isolate acoustic speech markers in a subtype of dysarthria resulting from Parkinson’s disease for my doctorate.

Working as a research assistant on the Innovation Fellowship, on the development of ultrasound as a new clinical assessment tool of swallowing function. The project involves collecting data of normal swallowing, developing standard measurements and applying machine learning to the analysis process.

I have a keen interest in phonetics and speech production in speech and communication disorders - with a particular interest in articulatory problems in speech. Have a drive to conduct research that could combine speech research and speech technology, or machine learning to strengthen diagnosis and intervention of speech, and language disorders.

My doctorate study aims to isolate acoustic markers in speech unique to hypokinetic dysarthria associated with Parkinson’s disease and are trackable across two time points in one year. These markers may act as indicators for Parkinson’s motor symptoms progression. Acoustic analysis is chosen as the method of investigation to provide a more quantifiable way of looking at speech production by isolating specific patterns in the speech signal.

The speech markers found may be used as a robust supplement to existing methods of hypokinetic dysarthria evaluation and further ease the role of the speech and language therapist during assessment, and give patients access to a more quantifiable way of tracking their speech.
