Gloria Estefany Amaris Castro
About
I have more than 13 years of experience in choice modelling, combined with a strong understanding of real-world systems and the behavioural forces that shape them. My work is grounded in the belief that meaningful solutions to global challenges must account for how people think, decide, and act.
I specialise in mathematical modelling to understand and predict human decision-making processes. By integrating principles from choice modelling, psychology, and environmental sciences, I develop advanced models that address real-world challenges, particularly those related to sustainability, climate change, and emerging markets. Through my work under the ChoicemodAnalytics brand, I draw on expertise in behavioural sciences and sustainable urban systems, with a strong focus on people as the key agents driving demand. This approach generates actionable insights to support informed policy decisions across environmental, social, and engineered systems.
Research
My research examines how human decision-making shapes demand, system performance, and policy outcomes in environmental, social, and engineered systems. I focus on developing behavioural and choice-based modelling frameworks that capture how individuals respond to incentives, constraints, and uncertainty in complex, real-world contexts.
A key contribution of my work lies in advancing mathematical and econometric models that integrate behavioural theory with empirical data. I study heterogeneity in preferences and decision rules, and I design models that move beyond fully rational assumptions to better reflect observed behaviour. These frameworks are applied to problems in sustainability, climate change mitigation and adaptation, urban and transport systems, and the analysis of new and evolving markets.
My research is inherently interdisciplinary, drawing on choice modelling, psychology, environmental sciences, and systems analysis. By embedding behavioural responses within policy and system-level models, my work aims to improve the design and evaluation of interventions, supporting decisions that are both analytically robust and behaviourally realistic.
