Topic: The Joseph’s lab investigates the complexity of the interplay of biological and behavioral components in addressing symptoms and managing medical problems relevant to nursing science, with a special emphasis on metabolic disorders like obesity and diabetes. The main focus of the laboratory is to understand the role of sensory science in metabolic disorders and use this information towards the development of novel treatments. Furthermore, the laboratory is interested in the interplay between metabolic disorders, sensory-related pathways and brain diseases, in particular alcohol and substance use disorders.
Issue: Each year, over 200,000 people visit a medical provider for chemosensory problems such as taste and smell disorders. When smell-taste perception is distorted and poorly treated, altered eating may still occur thus worsening health outcomes.
Impact: Dr. Joseph and her group are conducting pre-clinical, clinical and translational studies that aims to improve the diagnosis, prevention, and management of chemosensory disorders and symptoms. Dr. Joseph’s laboratory is leading research that is aimed at enhancing the understanding of molecular, cellular, neural, and behavioral mechanisms underlying symptoms to identify new targets for treatment and improve symptom management strategies. As a nurse and family nurse practitioner, Dr. Paule Joseph has worked extensively with individuals with diabetes and obesity, individuals undergoing weight loss surgery and alcohol and substance use disorders. Dr. Joseph brings a unique and necessary perspective to the study of chemosensory symptoms (taste and smell alterations) by incorporating both clinical and bench science approaches to unite three fields of science: nursing, sensory biology, and omics.
