Meet Dr. Deliyianni!
Dr. Maria Deliyianni is a fourth-year postdoctoral research associate in the Department of Mathematics, working with Dr. Shankar C. Venkataramani. Her work revolves around nonlinear partial differential equations – math describing how physical quantities flow or spread – and their engineering applications.
Maria began her academic journey in Cyprus, where she earned a Bachelor's degree in Applied Mathematics at the University of Cyprus before relocating to the United States to pursue a PhD in Applied Mathematics (University of Maryland, Baltimore County). During her doctoral studies, she had the opportunity to experience a different and rather more collaborative research environment, which fostered her engagement in mathematical research and interest in pursuing research at the postdoctoral level.
Today, her research centers on partial differential equations (PDEs), a mathematical framework used to model real-world phenomena, such as how fluids like air and water move and interact. Specifically, Dr. Deliyianni studies how flexible structures, such as thin beams or plates, bend and vibrate when exposed to fluid flow – much like a diving board responding to a jump. These dynamics are key to flow-induced energy harvesting, where vibratory motion can be converted into electrical energy using devices attached to the structure, helping inform more sustainable energy technologies. In addition to interactions between fluids and structures, her research explores a broader range of complex nonlinear mathematical systems.
Beyond her research activities, Dr. Deliyianni is also committed to teaching and supporting the next generation of mathematicians. Her teaching philosophy emphasizes training in critical thinking, and encourages students to develop transferable problem-solving skills rather than focusing on solving specific types of problems. Notably, Dr. Deliyianni's teaching has been recognized with a departmental teaching and service award at the University of Arizona.
During her time at the University of Arizona, Dr. Deliyianni appreciated the strong sense of community within the Department of Mathematics and particularly enjoyed the weekly postdoc group seminars. She encourages early-stage postdocs to take advantage of departmental and university-wide resources, including guidance on writing strong grant applications and opportunities for professional development.
