Iulian Ilies, PhD

    • LinkedIn - Grey Circle

    Iulian is a Research Scientist with interests and expertise in the broader area of exploratory data analysis. He has received his interdisciplinary education in mathematics, statistics, computer science and cognitive psychology from Jacobs University in Bremen, Germany, and has over 10 years of research experience in applied and computational statistics, mathematical modeling, and operations research. At HSyE, he is the technical lead on the surgical site infections and opioid epidemic modeling projects, provides predictive analytics support for other projects as needs arise, and is exploring the incidence and impact of multimodality on healthcare duration data. His previous work includes cluster analysis and classification of high-dimensional data, time series analysis and forecasting, image segmentation and reconstruction, modeling of nonlinear growth processes, and applications of general linear models and correlation analysis. When not working, Iulian enjoys hiking, exploring the nature preserves of the greater Boston area, reading fantasy fiction, occasionally drawing, or simply keeping up to date with the latest topics in science and technology.
