I studied mathematics and biochemistry as an undergraduate and have been developing statistical models and image processing software since my first research position at the NIH NIBIB in 2013. I am focused on developing AI technologies to automatically segment, detect and analyze hepatocellular carinoma tumors at large scale from MRI pre-treatment imaging studies in order to improve patient selection and therapeutic outcomes.

Md Manjurul Ahsan, Ph.D.

I am a Postdoctoral Research Associate at Northwestern University, where I am working with Dr. Ulas Bagci as my principal investigator. Prior to this, I completed my Ph.D. at the University of Oklahoma under the guidance of Dr. Shivakumar Raman and Dr. Zahed Siddique. During my time at the University of Oklahoma, I worked as a research assistant on numerous projects, including machine learning-based disease diagnosis and optimal machine learning-based additive manufacturing. Additionally, I had the opportunity to develop two VBA software applications for Schlumberger. My research interests lie in developing artificial intelligence-based optimal solutions that are interpretable and accessible to researchers, practitioners, and users. Currently, my research focuses on developing novel explainable deep learning (DL) algorithms to identify patients at risk for the development of PASC pulmonary fibrosis (PF). This work involves combining imaging (initial CT scan) and electronic health record (EHR) data from multiple centers.
