Wei Lin

I am a research associate at the Institute for Machine Learning headed by Prof. Sepp Hochreiter (Father of LSTM) at the Johannes Kepler University (JKU) Linz.

I did my PhD at the Institute of Computer Graphics and Vision, Graz University of Technology (TU Graz ICG) in Austria, supervised by Prof. Horst Bischof (Professor and the Rector of TU Graz) and Prof. Hilde Kuehne (University of Bonn, Goethe University Frankfurt, MIT-IBM Watson AI Lab)

I also work in close collaboration with Leonid Karlinsky and Rogerio Feris (Principal scientists and research manager) from the MIT-IBM Watson AI Lab.

Previously, I received my Master's degree in Electrical and Computer Engineering at the Technical University of Munich in Germany, and my Bachelor's degree in Eletronic and Information Engineering at the Beihang University in China.

I like traveling 🥾 and learning languages 🌍.

I am interested in computer vision and machine learning in general. My research is mainly about vision-language models, multimodal learning, domain adaptation and video understanding.
