Sergiu Nisioi
Hello!
I am an Assistant Associate Professor (since Febr. 2024) within the Faculty of Mathematics and Computer Science, University of Bucharest.
My research is related to various areas of computational linguistics, covering topics such as computational psycholinguistics, computational learning theory, bias, machine translation, and text simplification. In addition to academic research, for the past ten years I have been deploying machine learning pipelines in production. Some projects are visible on GitHub and on semantic scholar.
I’m also interested in sound art, algorithmic compositions, DSP, and modular synthesizers: former noize maker as part of godwana sound project, diy ecological research for chlorophylla.live, and part of HYPHA.ro initiative for digital autonomy.
