Background

Maryann Siloko Amos is a doctoral researcher in Environmental Sustainability at ³ÉÈËÖ±²¥. She has an academic background in Geology and Environmental Management, with research interests in environmental quality assessment, geospatial analysis, and climate–pollution interactions. Her PhD research examines the geospatial analysis of climate change variability, air pollution, and human exposure in the Niger Delta region, using advanced satellite datasets and spatial modelling techniques to investigate environmental degradation and associated public health risks.

Before beginning her doctoral studies, Maryann conducted a soil quality evaluation of land‑use patterns in the urban fringe areas of Port Harcourt. She also carried out a comprehensive water quality assessment across communities in Ogbia Local Government Area, Bayelsa State.

Current activities

Maryann Siloko Amos is currently engaged in doctoral research on the geospatial analysis of climate change variability, air quality degradation, and human exposure in the Niger Delta region of Nigeria. Her work involves analysing multi‑decadal satellite datasets, including MODIS/AOD, Landsat, MERRA‑2, and NiMet climate records, to quantify long‑term trends in key air pollutants and assess the influence of climate variability on pollution patterns.She is developing spatial models to identify pollution hotspots using the Getis‑Ord Gi* method and constructing population‑weighted exposure surfaces through dasymetric mapping techniques. Her ongoing work includes producing composite environmental risk maps using Multi‑Criteria Decision Analysis (MCDA) to determine the vulnerability of communities across the Niger Delta, with particular attention to areas experiencing high pollution burdens and climate‑related stressors.In addition to her PhD research, Maryann continues to build on her previous environmental assessment work, which includes soil quality evaluation in the urban fringe areas of Port Harcourt and a comprehensive water quality assessment across communities in Ogbia Local Government Area, Bayelsa State. Her current activities reflect a strong commitment to environmental sustainability, geospatial science, and evidence‑based approaches to climate and public‑health challenges.
