Profile Summary

Applied computational scientist and research leader with over 20 years of experience developing and validating high-performance numerical and experimental models, probabilistic risk assessment methods, and large-scale data pipelines. I have a PhD in nuclear engineering with a minor in applied mathematics. My career spans across organizations such as Argonne National Laboratory, GE Hitachi Nuclear Energy, and international collaborations, where I directed DOE- and industry-funded projects. The projects I contributed to and led focused on computational fluid dynamics, numerical solvers, experimental validation, multiphase flow, uncertainty quantification, scenario modeling, and risk-informed decision frameworks for complex energy systems. I have a deep expertise in combining physics-based modeling with advanced machine learning to analyze high-dimensional, noisy data and translate results into actionable insights for stakeholders ranging from regulators to industry partners. Fluent in several languages (English, Spanish, French) and experienced as both a Principal Investigator and adjunct lecturer. I have a proven record of performing cutting-edge research, leading multidisciplinary teams, mentoring researchers, and shaping research agendas that bridge scientific rigor with practical, real-world outcomes.
