Researcher biography
My goal as a researcher is to conduct research that both advances theory and has practical impact. My research focus is on using computational models to understand how humans make decisions in dynamic, complex, and uncertain environments. Practical applications of this work include enhancing the capacity and safety of unmanned aerial systems operation, facilitating tactical decision-making in military contexts, providing tools to combat fatigue in submarine operations, and improving climate change mitigation practices.
