Summary
👤
Senior🎓
Top SchoolMohammad Zeineldeen is a Speech Scientist and PhD candidate at RWTH Aachen University with a decade of engineering and research experience advancing end-to-end and streaming ASR systems. He combines academic rigor under Prof. Hermann Ney with industry impact at AppTek.ai, where he develops robust multilingual ASR and explores SpeechLLMs. His work spans acoustic and language modeling, neural LSTM variants, and practical deployable systems—evidenced by contributions improving LSTM layer normalization and stability in the widely used returnn framework. He has applied knowledge distillation techniques during a Google Speech research internship and routinely supervises student projects, bridging research and hands-on mentorship. Known for improving core RNN components and adding clear documentation, he brings both deep algorithmic insight and production-aware engineering to speech technology.
