My research interests lie at the cross-cutting areas of information visualization, visual analytics, human-centered data science and human-computer interaction.


Background
Currently (since Fall 2018) at NJIT, I am leading the development of a new research program around data visualization and visual analytics.

Before restarting my academic journey, I spent three productive years as a research scientist at PNNL, where  I had the pleasure of collaborating with experts from diverse backgrounds such as biology, climate science, machine learning, cyber security, etc. I led multiple interdisciplinary projects funded by the DOE's Lab-Directed Research and Development Program.



I am seeking highly motivated PhD students (fully funded positions) to work with me on projects related to the issues of trust, transparency, and interpretability in human-data interaction. The goals of these projects will be to develop and evaluate novel visualization and visual analytic techniques for making data accessible, interpretable, and actionable to people with diverse backgrounds and skills.

Please contact me directly or look at this document for more details about these positions.
