After receiving his doctoral degree Faiz worked at the Korea Research Institute of Bioscience & Biotechnology (KRIBB) where he was involved in generating different genetic mice strains and analyzed their biological characteristic & behavioral phenotypes under the umbrella of “Korea Mouse Phenotype Center”. He studied for his PhD at the National Creative Research Laboratory for Signaling Network, Chonbuk National University South Korea. He focused on the roles of gasotransmitters i.e. carbon monoxide and nitric oxide in Ca2+ Signaling for Insulin Secretion in Type2 diabetes using mouse model. In addition, he also investigated the role of nicotinamide adenine dinucleotide (NAD), a substrate for CD38/SIRT1 enzymes in hematopoiesis regulation. He previously received an MS/M.Phil degree from the Human Molecular Genetics Laboratory at Quaid-i-Azam University, Pakistan. This involved studies on epigenetic gene regulation.
