Dr. Gabriella Colajanni is currently a Research Fellow in the Department of Mathematics and Computer Science at the University of Catania, Italy. She received her Ph.D. in Mathematics and Computer Science in 2019 and her master’s degree in Mathematics from the University of Catania. Her current field placement is Operations Research.

Her research focuses on linear and nonlinear constrained optimization models based on networks and on optimization of UAV networks using 5G technologies.

She is interested in supply chain networks, variational inequalities, traffic and equilibrium problems, portfolio selection problems, cloud computing models, business management, cybersecurity, UAVs, and 5G networks.
