Arif was born and brought up in Dhaka, Bangladesh. He obtained his B.S. and M.S. in Biochemistry in Molecular Biology with distinctions from the University of Dhaka. During his M.S. thesis at the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) under Dr. Firdausi Qadri, Arif became interested in mucosal infection and immunity. Prior to his doctoral training, Arif worked on T-cell responses to gastrointestinal infections as an NIH Fogarty Fellow at Massachusetts General Hospital, Harvard Medical School. Arif earned his Ph.D. in Molecular Genetics and Microbiology from Duke University, where he studied innate immune defense mechanisms of mast cells and macrophages in Soman Abraham’s lab. He pursued his postdoctoral training with David Artis, focusing on the regulation of eosinophils by gut microbiota. During this time, he developed his current research program, which centers on understanding the role of diet and microbiota in mucosal immunity and beyond. Arif is interested in studying the signaling pathways of various microbiota-derived small molecules that influence host immunity in the contexts of infection, inflammation, metabolic homeostasis, and cancer. He aims to define the molecular mechanisms of immunoregulation mediated by dietary and microbial components, with the goal of designing precision nutrition and therapeutics to prevent and treat disease. Arif’s less scientific interests also include a passion for food and diet, as he enjoys learning about food culture and food psychology across different parts of the world, as well as discovering the endless culinary options that New York City has to offer.
