About

Overview

I am a Lecturer in City's Computer Science department and a member of its giCentre. My expertise is in data visualisation and visual analytics, and as part of my research I seek to understand how people think with and learn from digital visual content.

Qualifications

PhD Computer Science (focus on Visualisation), Brown University, USA, 2012
MSc Computer Science, Brown University, USA, 2007
BSc Computer Engineering, Polytechnic University Timisoara, Romania, 2005

Employment

2016 - present: City, University of London, UK
2012 - 2016: Florida International University, USA

Research

My research is focused on Visualisation, Visual Analytics, and Human Computer Interaction. Broadly, I'm interested in understanding how people explore, think with, and learn from digital visual content and data, and in creating novel methods that can support such activities. I investigate novel approaches that build on eye-tracking and user-study experimentation, and work with researchers in domains such as construction, architecture, and biology to discover how to facilitate novel insights into visual information consumption in practice. At the same time, I explore the interactive use of eye-tracking to create adaptive, gaze-contingent visualisations, and support the guided exploration of large data spaces.
