I am a Postdoctoral Research Scholar in the Wang group in the Radiological Sciences Laboratory (RSL) at Stanford University.

I obtained my PhD in Computer Science from the University of California, Los Angeles (UCLA) in 2020 under the supervision of Distinguished Professor Demetri Terzopoulos. During my PhD, as a member of the UCLA Graphics and Vision Lab, I worked on developing effective deep learning techniques for medical image analysis.

Earlier, I received an MS in Computer Science degree from Delaware State University (DSU) in 2016 and a Bachelor in Computer Science and Engineering (CSE) degree from Rajshahi University of Engineering and Technology (RUET), Bangladesh in 2012.

Previously, I worked in the Medical Imaging and Simulation (MEDIS) Lab at DSU in collaboration with the Penn XPL Lab, jointly advised by Professor David Pokrajac and Professor Predrag Bakic. I have also spent time at Philips Corporate Research NA at Cambridge, MA and Tencent Medical AI Lab at Palo Alto, CA.

Research

My research is primarily centered around artificial intelligence, computer vision, and medical imaging. I am particularly interested in developing advanced AI-powered medical imaging tools for clinical applications. Recently, I focus on semi-supervised learning with multi-task learning, self-supervised learning, and generative modeling. I am also interested in visual representation learning and domain generalization for medical image analysis tasks.
