Sergül Aydöre

Applied Scientist at Amazon Web Services - Machine Learning Researcher

I am an applied scientist at Amazon Web Services focusing on privacy and security problems. Prior to AWS, I was an Assistant Professor at the department of Electrical and Computer Engineering of Stevens Institute of Technology. I received my PhD degree from the Signal and Image Processing Institute at the University of Southern California in 2014 under the supervision of Richard M Leahy . My PhD thesis was on Measuring Functional Connectivity of the Brain . After finishing my PhD, my research interests have changed towards machine learning algorithms. I was lucky to work with great researchers Gaël Varoquaux , Bertrand Thirion and Dean Foster.

Research

As a researcher, I am interested in robustness and generalization properties of machine learning models. Below are brief highlights of my research interests.

Robustness to Bad Samples
Robustness to Concept Drift
Robustness to Overfitting
