Rodolfo A. Romarate II received his PhD in Environmental Science from Mindanao State University–Iligan Institute of Technology (MSU-IIT) in 2025 and is now serving as a faculty member at the Graduate Studies of MSU-IIT. His research mainly focuses on atmospheric microplastics, suspended airborne microplastics, emerging pollutants, road dust microplastics, air quality, environmental pollution, and microplastic contamination in Philippine urban environments. He has contributed to pioneering studies on atmospheric microplastics in the Philippines, particularly on the presence of suspended microplastics in Metro Manila, their diurnal and seasonal dynamics, potential health risks, and the role of road-associated microplastics as possible sources of airborne plastic particles. His work also extends to microplastics in road dust, mangrove sediments, and broader environmental systems involving air, water, soil, and coastal environments. Romarate has collaborated with researchers from MSU-IIT, other Philippine universities, and international institutions, with publications in journals such as Environmental Science and Pollution Research, Journal of Hazardous Materials, Water, Air, & Soil Pollution, Philippine Journal of Science, and Marine Environmental Research. His scholarly work supports the development of baseline data for emerging contaminants in the Philippines and contributes to evidence-based environmental monitoring, pollution management, and public health.
