Jerome specializes in modeling the Water-Energy-Food-Ecosystem (WEFE) nexus, focusing on interactions between land, water, and ecosystems. His research aims to develop case-specific methodologies to support sustainable watershed and landscape management. By integrating hydrology, landscape ecology, and spatial data analysis, Jerome addresses the complex interconnections and trade-offs involved in managing natural resources.

A core aspect of his work is tailoring nexus methods to the unique characteristics of watersheds and landscapes. This involves identifying key drivers and pressures on water and land systems, assessing ecosystem dynamics, and exploring strategies to optimize ecosystem service delivery. Using tools like the Soil and Water Assessment Tool (SWAT), Jerome models hydrological processes and evaluates their impacts on ecosystems and communities. He complements these models with machine learning and spatial-temporal data analysis to uncover patterns, predict trends, and assess future scenarios.

Jerome’s research also emphasizes the development of decision-support tools to inform policymakers and stakeholders. These tools combine scientific rigor with practical utility, facilitating the integration of nexus principles into resource management and planning. By addressing challenges such as trade-offs between agricultural productivity, water availability, and ecosystem health, Jerome contributes to advancing holistic, multidisciplinary approaches to managing the water-land-ecosystem nexus. His work underscores the importance of balancing human needs with environmental sustainability, providing insights critical for improving watershed and landscape resilience in the face of climate change and resource pressures.
