Professional Profile

Dr. Hiranuma joined WTAMU in 2016 after earning an 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. Both awards include 5-year grants to support the university mission and achieve his career objective, which is an integration of climate science and pedagogy. From Japan, he now lives in Amarillo, where he is deeply involved in outreach collaborations with local organizations and agencies in the 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 integrating research and teaching. Combining the topics of chemistry, physics, and climate 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. At WTAMU, he has serrved as a research mentor for 2 postdoctoral research associates and 16 students.

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.

Dr. Hiranuma heads the Atmospheric and Aerosol Measurement Laboratory (A 2ML) for an integrated laboratory and field studies. The research capabilities of A 2ML 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 physicochemical 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 these capabilities enables to comprehensively assess what aerosol particle properties (i.e., chemical, physical, and/or biological) matter the most for cloud formation.
