Postdoctoral Research Fellow
Overview
Dr. Ayaho Yamamoto is the Group Leader of Laboratory Science at the Children's Health and Environmental Program and is a research fellow in the field of Biomedical Science. Her research focuses on understanding the mechanistic links between environmental exposures and adverse respiratory outcomes. In particular, focuses on the cellular responses following air pollution exposure and/or viral infection on human respiratory epithelium, and the age differences in immune defence mechanisms. Investigate on early intervention strategies with dietary antioxidants to improve respiratory health and reduce the risk of long-term chronic diseases.
Dr. Yamamoto has a Bachelor of Science in Environmental Health and Public Health; her research focused on childhood asthma. She has a Master of Science in Biomedical Science and Pharmacology; the research focus was to understand the mechanisms and to test new drugs for osteoporosis and chondrosarcomas metastasis. She has worked in a Uni-based start-up company for drug development.

Why are some people more likely to develop respiratory diseases from environmental exposure and suffer more severe respiratory infections?
In our previous studies, we found that some individual humans are more susceptible to air pollution exposure than others. However, it is unclear that what factors impact on this phenomenon. In this project, we will combine clinical data with biological specimens to investigate the health risk from pollution exposure on human subjects.
Clinical aspect: conduct surveys with patients or volunteers.
Laboratory: work with respiratory cells collected from the human subjects to determine the factors impact on individual susceptibility to adverse environmental exposures and how this translates into poor respiratory health.
Outcomes: identify factors impact on poor respiratory health from surveys and cellular experiments.
You will have the opportunity to gain both clinical and lab experience.

Impact of environmentally persistent free radical exposure on respiratory epithelium
Exposure to poor air quality is associated with adverse respiratory health. Environmentally persistent free radicals (EPFRs) are combustion products present in substantial numbers on atmospheric particulate matter that have half-lives of days to years. EPFRs can induce oxidative stress and have long lasting effect on biological systems, however, the mechanistic links between EPFR exposure and respiratory diseases are still unclear.
This project aims to develop a chronic EPFR exposure model using VITROCELL® Cloud 12 system and use this model to examine the innate immune and cellular responses, as well as mitochondrial function in fully differentiated respiratory epithelium culture at air-liquid interface.
This project would suit a student with a background in cell and molecular biology. Knowledge of or experience in basic laboratory techniques such as cell culture, immunofluorescence and western blotting would be helpful.
