About

I am a postdoctoral researcher at Linneaus University in the IsoVis group, working in Visual Analytics, Information Visualization, and Human-Computer Interaction.


I earned my Ph.D. in Computer Science from Stony Brook University under Prof. Klaus Mueller's at the Visual Analytics and Imaging Lab, where my research focused on lowering barriers to data visualization. I also co-founded 12bit AI, working on synthetic medical imaging data for AI-driven AI workflows, and previously worked as a Founding Software Engineer at Akai Kaeru on tools for accessible data analysis.


My research interests include human-centered visual analytics, visualization for AI and machine learning (including explainability and interaction), visualization design and literacy, and collaborative, task-oriented analysis systems.
