Mohammad Hassan Vali is a Postdoctoral Researcher in the Department of Computer Science at Aalto University, Finland. His postdoctoral research, supervised by Prof. Arno Solin and funded by the Finnish Center for Artificial Intelligence (FCAI), focuses on discrete representation learning in deep neural networks. In particular, his work explores efficient vector quantization techniques with applications in image and speech processing, including image compression and generation, 3D Gaussian splatting compression, interpretable AI, speech privacy, and voice conversion.
He earned his Ph.D. in Electrical Engineering from Aalto University in 2025, where his doctoral thesis, “Vector Quantization in Deep Neural Networks for Speech and Image Processing,” was supervised by Prof. Tom Bäckström. He received his B.S. and M.S. degrees in Electrical Engineering from Babol Noshirvani University, Iran, in 2014 and 2017, respectively.
