Jilliane Lagus

Jilliane Lagus

Jilliane Marai Lagus, MS, CCC-SLP, is a pre-candidacy doctorate student under the mentorship of Dr. Corinne Jones at the Swallow Modulation Laboratory. She completed a BS in Speech Pathology at the University of the Philippines Manila and an MS in Communication Disorders at the University of Texas at Dallas. Jilliane is interested in the thoughtful examination of the neuroscience of the aging swallow using data science techniques to unearth development patterns otherwise undetectable by manual or traditional analysis. A deeper understanding of how healthy humans eat and drink safely well into vulnerable older age will help clinicians determine better interventions that can help prevent or mitigate swallowing disorders and their effects (malnutrition, dehydration, death). Off-duty, Jilliane's goals include walking 10,000 steps a day, listening to audiobooks at x2 speed, watersports, and learning about new languages and food.
