Associate Professor, Department of Mathematics and Computer Science
"Modern methods of data analysis include not only traditional statistical approaches, but also new techniques that are motivated by the complexity and size of the information around us. I am excited to explore different ways of visually representing data and to analyze the insight that such an approach can give. My topological background helped me better understand the ways in which ideas from a presumably unrelated field can be applied in this area with amazing results. I am enthusiastic about the multiple applications of data visualization and the perspectives and intuition that a graduate of our program will have when taking these ideas in solving concrete tasks."
With numerous awarded fellowships, Bogdan Vajiac is well-versed in the kind of research that graduate students need. In the Master of Science in Data Science program, Vajiac will focus on the visualization of data.
