Profile bio
About Thomas Hayashi
Connections between the environment and technology are fundamental to creating a sustainable future. My specialization primarily relates to implementing machine learning solutions and spatial data analyses to ecological or novel biostatistical problems. I'm a co-author on a paper where we implemented random forest machine learning algorithms in R for grass ecology. In this paper, I worked to help predict the variations in California grasses depending on the regions where they grew and the climatic variables associated with each region. My graduate thesis related to implementing machine learning pipelines in Python in order to generate accurate and precise classification algorithms for wetland restoration while also comparing the performances of various models. These algorithms predicted the appearances of at-risk wetland bird populations in an attempt to help guide restoration efforts. I presented this research with my research team at the 2020 Ecological Society of America conference.My professional background primarily relates to spatial data analysis, predictive modeling, and data visualization. Previously, I was contracted with the California Department of Public Health as a research data analyst through the Sequoia Foundation. As a contractor I worked on several wildfire health impact publications including the full stack development of the California Wildfire Smoke and Air Pollution Health Burden Mapping Dashboard web application. Currently, I am a Research Scientist II within the Environmental Health Investigations Branch for the California Department of Public Health. I study the latest literature on harmful algal blooms and their impacts on public health in California. Additionally, I interface with a statewide interagency network, as well as local level counties to help mitigate negative human and animal outcomes related to harmful algal blooms. Lastly, I document all individuals potential harmed by algal blooms in California and guarantee the maintenance and accuracy of California’s HAB database.My Bachelor's in Environmental Studies helps guide me to think of wholistic solutions, taking into consideration all elements of a problem, while my Master's in Information Systems helps me to pinpoint exact solutions to systemic issues. Being born and raised on Maui helped instill in me a reverence for nature and for protecting human health. The culmination of my academic work, research, and professional career give me the toolset to be an effective research scientist to protect California’s public health against harmful algal blooms.
Listed skills include R, Computer Science, Economics, Ecology, and 3 others.

Research Scientist Ii
CurrentLead scientist from the California Department of Public Health - Environmental Health Investigations Branch studying harmful algal blooms in California. I primarily analyze and investigate human case reports and assist with the surveillance of any toxic blooms across the state. I communicate extensively with additional HAB monitoring organizations throughout the state and contribute in the maintenance of California’s internal One Health Harmful Algal Bloom dashboard and California’s contributions towards CDC’s National Harmful Algal Bloom Database. Additionally, I am a co-representative for CDPH and California in CDC’s National Harmful Algal Bloom Community of Practice. In the future, I hope to develop a GIS application to help inform the public of harmful algal bloom vulnerability.
