Travelling from 23 September. I'll be in Sydney for Interspeech 2026, so replies may be slow for a couple of weeks.
My broader interest is in learning robust representations of human signals across modalities when data, labels, or linguistic resources are not clean or limited. Bengali is one important testbed for some of my works, but the methods I am interested in are intended to generalize across languages and modalities.
I am currently a research assistant at BUET with Dr. Muhammad Abdullah Adnan, an R&D engineer at TigerIT working on face and iris biometrics, and an adjunct lecturer at Presidency University. I also lead SignSpeak, an incubator project very close to my heart.
