Dimitris Berberidis
Welcome
I'm Dimitris, and I am currently a Post-Doctoral Fellow working with Prof. Leman Akoglu at the H. John Heinz III College at Carnegie Mellon University. I obtained my PhD in 2019 from the Electrical and Computer Engineering (ECE) Department at the University of Minnesota, under the supervision of Prof. Georgios B. Giannakis.
My research interests span the areas of Network Science, Machine Learning, and Statistical Signal Processing. Specifically, I am interested in the discovery of simple yet expressive models, and the development of flexible and scalable algorithmic frameworks, accompanied by efficient and portable software tools.
Currently I am focused on learning over graphs, and particularly on embedding, classifying and detecting anomalies on large and possibly multilayered networks that arise from real-world processes.
