Ehsan is currently a post-doctoral researcher at Northwestern University Feinberg School of Medicine in the Department of Preventive Medicine-Health and Biomedical Informatics. His research focuses on social media, scholarly communication, online information behaviour, open science, information visualization and health informatics.
Before moving to Chicago, he was part of a research team at the Science Park at the University of Wolverhampton, UK to evaluate the Knowledge Exchange & Enterprise Network (KEEN) program.
Ehsan completed his PhD in Information Science from the Statistical Cybermetrics Research Group at the University of Wolverhampton, UK with Professor Mike Thewall. In his doctoral dissertation, he conducted a large-scale online survey and used massive quantitative data analyses of several online social platforms to provide evidence that social media metrics, known as alt(ernative)metrics, are able to capture otherwise invisible types of research impact that cannot be recognized through traditional metrics.
He also holds a master's degree in Library and Information Science. In the master's dissertation, text-mining and information visualization methods were used to map Nano science and technology publications.
To date, Ehsan has served as a lecturer and course designer on foundational and emerging courses related to information science at several universities, in both face-to-face and online settings.
