About Me

Hello there, I'm Avijit, Welcome to my personal website! I am a PhD candidate at the Manning College of Information And Computer Science, UMass Amherst. I am advised by Professor Hong Yu in the UMass BIONLP Lab. I completed both my BSc and MSc in Electrical and Electronic Engineering at Bangladesh University of Engineering and Technology (BUET).

With a strong foundation in both engineering and computer science, I've had the privilege of interning at Amazon Alexa AI for three consecutive summers (2021, 2022, 2023). My research now revolves around the development and practical implementation of Natural Language Processing (NLP) systems in the healthcare domain, with a specific focus on harnessing clinical data, including Electronic Health Record (EHR) notes.

Before embarking on my PhD journey, I contributed as a Machine Learning Researcher at Semion, where I dedicated my efforts to crafting and deploying AI-driven solutions in the realm of healthcare. My passion lies at the intersection of cutting-edge technology and its transformative impact on healthcare, and I am committed to advancing the field.
