Professional Profile

Dr. Hiranuma joined the Department of Life, Earth and Environmental Sciences (LEES) in 2016. He received a Ph.D. in Atmospheric Sciences from Texas A&M University in 2010 and completed post-doctoral training at Pacific Northwest National Laboratory in 2012. Before joining LEES, he was at Karlsruhe Institute of Technology in Germany to work on the German government-funded INUIT (Ice Nuclei research UnIT) project, and he led the collaborative multi-institutional laboratory work with a total of 14 institutions, including seven from Germany (e.g., University of Frankfurt), four from the US (e.g., Colorado State University), one from the UK (University of Leeds), one from Switzerland (Swiss Federal Institute of Technology in Zurich) and one from Japan (Meteorological Research Institute), to comprehensively study the heterogeneous ice formation of dust and biological aerosols in the atmosphere.

Teaching and Related Service

Dr. Hiranuma teaches research methods in environmental science, numerical methods in environmental science, fundamentals of environmental science, environment & man, GIS and associated lab courses. He also serves as an editorial board member of scientific journals (e.g., Advances in Environment and Pollution Research) and a proposal reviewer. He has published more than 10 first author peer-reviewed papers and presented the research at national and international scientific meetings on a regular basis. Dr. Hiranuma is a member of the American Geophysical Union (AGU) and European Geophysical Union (EGU). He is internationally sought after for scientific community services (e.g., chairing/conveying/judging scientific sessions of AGU and EGU).

Research and Creative Activity

Dr. Hiranuma’s research interests exist in quantification of atmospheric aerosol-cloud-climate interactions, weather modification (e.g., precipitation enhancement, hail prevention) and assessment of aerosols’ impact on public health. At West Texas A&M University (WTAMU), he applies advanced aerosol measurement techniques to generate new knowledge on the aerosol-cloud interactions and mitigating regional concerns of agricultural dust that contains fine, coarse and biological aerosols on air quality and weather (e.g., hail) in the Texas Panhandle.

Dr. Hiranuma heads the Atmospheric and Aerosol Measurement Laboratory (A2ML) for an integrated laboratory and field studies, representing a new research capability of WTAMU. The research capabilities of A2ML include (1) quantifying atmospheric ice-nucleating ability of aerosols using an ice nucleation chamber, (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 (e.g., ESEM, EDX, Raman Microspectroscopy, STXM), 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 properties (i.e., chemical, physical or biological) matter the most for cloud formation.

Personal Sketch

Dr. Hiranuma lives in the Greenways of Amarillo with his wife Natsuko and their two daughters, Yuna and Sona. Dr. Hiranuma’s family members have diverse cultural backgrounds, and they like adventures.
