Julie Regan

Julie completed her PhD in the School of Medicine in Trinity College Dublin (TCD) in the Autumn of 2013. Her PhD thesis was entitled 'Adaption of Functional Lumen Imaging Probe to Evaluate the Upper Oesophageal Sphincter in Oro-pharyngeal Dysphagia'. Julie completed an MSc in TCD in 2006 and researched the effects of thermal-tactile stimulation on swallowing in Idiopathic Parkinson’s Disease during videofluoroscopy. She graduated from the School of Clinical Speech and Language Studies in TCD in 2000 and has over ten years clinical experience in the assessment and management of adult dysphagia in Tallaght Hospital.

Julie has post-graduate training in videofluoroscopy, pharyngeal manometry, surface electromyography, fibreoptic endoscopic evaluation of swallowing (FEES), Deep Pharyngeal Neuromuscular Stimulation and Vitalstim. She lectures on neurology and dysphagia at undergraduate and postgraduate level in the School of Clinical Speech and Language Studies, TCD. She has peer-reviewed publications and is full member of the Dysphagia Research Society (DRS).She is interested in the role of trans-nasal gastroscopy as a screening method for upper gastrointestinal disease and is currently developing a Dysphagia Evaluation Clinic under the auspices of TAGG

Asal Al Haddad

Asal Al Haddad graduated with a BSc degree in Biomedical Engineering from Jordan University of Science and Technology (JUST) in 2014. She worked in the clinical engineering department at Tallaght Hospital for 4 months in 2013 as part of her engineering training course and is currently working as a clinical engineer at the hospital. She is interested in doing research work on the functional lumen imaging probe (FLIP) under the supervision of Dr. Barry McMahon.

Maha Alqudah

Maha alqudah received her degree in Biomedical Engineering from the Jordan University of science and technology (JUST). Currently she is a PhD student in the department of Clinical Medicine in Trinity College Dublin (TCD). She works under the supervision of Dr. Barry McMahon. Her research interest is in using the functional lumen imaging probe (FLIP) in measuring the distensibility of the ano-rectal region in the human body. Currently output from this research is in press in one of the most prestigious gastrointestinal motility journals in the world. The paper demonstrates that the technique can rapidly determine the effect of the three major muscle components affecting the anal canal and consequently could revolutionise how ano-rectal function is perceived. The ongoing research aims to determine the exact mechanism underlying ano-rectal dysfunction in two distinct patient groups those with chronic intractable constipation and those with faecal incontinence, often as a result of trauma or prolapsed with the specific aim of designing appropriate biofeedback, medical and surgical therapies.

Prize: Best poster presentation on the 5th School of Medicine postgraduate research day in Trinity College Dublin (TCD) for poster titled; "Defining New Measures of Ano-rectal Function" 2012
