Professional Profile

Dr. Hiranuma joined WTAMU in 2016 as an assistant professor of environmental science after earning a M.S. degree from the same program and a Ph.D. in Atmospheric Science from Texas A&M University. In his career at WTAMU, he has been the recipient of the 2018 Early Career Research Program Award, funded by the U.S. Department of Energy, and the 2020 National Science Foundation CAREER Award, the organization’s most prestigious award that supports early-career faculty. From Japan, he now lives in Amarillo, where he is deeply involved in outreach collaborations with local organizations and agencies in teh Texas Panhandle.

 

Teaching and Related Service

Dr. Hiranuma teaches many in-person and online environmental science courses to both traditional and non-traditional students. His educational activities target intergrating research and teaching. Combining the topics of environmental science is an efficient and interesting tool to connect students with fundamental science by demonstrating how science provides information to interpret, digest and solve everyday life problems. He has developed and implemented a series of mobile online hands-on laboratory modules to achieve his goal. As for science community service, he serves as an editorial/topic board member of 3 journals (i.e., AtmosphereJournal of Environmental Science: Current ResearchJournal of Environmental Science and Allied Research).

Research and Creative Activity

Dr. Hiranuma’s research interests exist in atmospheric aerosol-cloud-climate interactions, precipitation and assessment of aerosol particles’ impact on public health. At WTAMU, he applies advanced aerosol particle measurement techniques to generate new knowledge regarding cloud microphysics and mitigating regional concerns of agricultural aerosol that contains fine, coarse and biological aerosol particles on air quality and weather in the Texas Panhandle.

Dr. Hiranuma heads the Atmospheric and Aerosol Measurement Laboratory (A2ML) for an integrated laboratory and field studies. The research capabilities of A2ML include (1) quantifying atmospheric ice-nucleating ability of aerosol particles using online/offline ice nucleation chambers, (2) cloud deconvolution by using counterflow virtual impactors, (3) characterization of physico-chemical properties of atmospheric particles and cloud residuals through a variety of single particle microscopy techniques, and (4) developing physical parameterizations of obtained experimental results and implementing in atmospheric cloud process, weather and climate models. A unique combination of given capabilities enables to comprehensively assess what aerosol particle properties (i.e., chemical, physical and/or biological) matter the most for cloud formation.
