Fnu Jaiprada

Research Fellow

I am International Medical Graduate worked as General Practitioner in my Home Country (Pakistan). My responsibilities include meticulously reviewing medical charts, extracting pertinent information, and entering this data into REDCap for further analysis.
My studies and areas of focus include improving the Precision of Management in Perianal Crohn’s Disease through Radiomic. While working clinically, I often felt that treating patients was incredibly fulfilling; however, I realized there was always so much more to uncover about the why and how behind the conditions we encounter. This curiosity sparked a deeper interest in understanding the underlying mechanisms of diseases, ultimately inspiring my transition into research.
