Charlotte Geier, MSc

Bio: Charlotte received her Master of Science in Theoretical Mechanical Engineering in 2021 from Hamburg University of Technology (TUHH) after completing her Bachelor of Science in General Engineering Science in 2017. During her studies, she spent two semesters abroad: She visited the INSA Toulouse (France) for the summer term of 2016 during her BSc. and the University of Waterloo (Canada) for a trimester in 2018 while pursuing her Masters Degree. In 2021, she joined the Dynamics Group as a research associate. In her free time, Charlotte enjoys exploring the "great outdoors" via sailing, hiking, climbing or simply the own garden.

Research: Charlottes research interests include nonlinear dynamics, complex networks, physics-informed machine learning and data-driven system identification of nonlinear dynamical systems. Her current research activities focus on complex network approaches as a novel perspective on nonlinear engineering vibrations. Previous research includes physics-informed machine learning applications for friction-excited systems.

Collaborations and student projects: Charlotte is happy to collaborate on projects regarding complex networks and nonlinear dynamics! Interested students can contact her via Email.
