General Information

Prof. Nilchiani is a tenured faculty member in school of Systems and Enterprises at Stevens Institute of Technology. She received her Ph.D. in Space Systems Engineering from the Massachusetts Institute of Technology (MIT) in 2005. In the past two decades, Prof. Nilchiani’s research has focused in the area of modeling and quantifying complex systems response to change. Within this area, she has made significant contributions to the quantitative measurement and computational modeling of agility, flexibility, adaptability, and resilience of various complex systems such as space systems, infrastructure systems, and telecommunication networks. Her most recent work explores the relationship between system complexity, uncertainty, emergence, and risk with an emphasis on developing new perspectives and conceptual frameworks for risk management. Her research group has been formulating and modeling quantitative measures of complexity and increased entropy in complex networks and engineered systems with multiple applications across various domains.
Her current research team has formulated a novel approach for identifying and localizing the tipping points of complex networked systems, the critical threshold across which a system can collapse, and are testing this new theory on case studies involving disruptive technology, ecosystem collapse, supply-chain sustainability, and biological cell death.
