Interactive Visual Analysis and Data Exploration Research


Lab.: http://ivaderlab.unist.ac.kr/

Open positions)
*I am looking for motivated undergraduate research interns and graduate students, who will love to design and evaluate novel user interfaces,
visualization techniques, interaction methods, and visual analytics systems (using deep learning).

*If you are interested in researching on human perception, cognition, interactions (even in VR and AR), deep learning interfaces and applications, please email me.

Important! To work with me you should contact me first before you apply. 

See my calendar to schedule a meeting: http://ivader.unist.ac.kr/my-calendar

Desired programing skills) Any combination of C++, Java,
Python, OpenGL, Unity, Web development (JavaScript, D3.js, WebGL, jQuery, Django, HIghcharts, Raphael, Bootstrap, MongoDB,  ...).
