Biography

Hi! Welcome to my website :)

I'm a Senior Machine Learning Engineer at Tulip Tech in Dhaka, Bangladesh, where I build agentic and voice-AI systems for healthcare. I received my B.Sc. in Computer Science and Engineering from Rajshahi University of Engineering & Technology (RUET).

My research asks how modern AI systems fail under real-world conditions, and how to detect and repair those failures without retraining: when do LLMs and agents state things they were never told, how much do vision–language models know about their own errors, and why do multilingual speech models stumble on rare letters and scripts? These questions come straight from the systems I have built in industry, from real-time Bangla voice agents to multi-agent assistants for healthcare.

I am applying to PhD programs starting Fall 2027. If our interests overlap, I would love to hear from you.

What I work on

Reliable LLMs and agents

When do language models and agents state things they were never told? I study fabrication and abstention in LLM outputs, and how agents that keep long-term memory handle the difference between what a user said and what the model inferred. I look for lightweight fixes that hold up across many models.

Uncertainty and interpretability in vision–language models

How much does a vision–language model know about its own errors? I study calibration and training-free hallucination detection, and whether mechanistic diagnoses of VLM failures actually turn into fixes that beat simple baselines.

Multilingual and low-resource speech

Text-to-speech for languages and scripts that large models underserve, starting from Bangla, with a focus on careful evaluation of where multilingual models break.
