Malaeb founded DLOC Biosystems in 2017, a biotech startup that is developing new technology to accurately predict drug failure in human trials to enable preclinical trials on-chip. This technology is expected to make clinical trials cheaper and safer. The organ-on-chip technology also aims to fully replace animal testing in the future. Wadah has five years of research experience in tissue engineering and biomedical engineering. He invented the first concept of DLOC’s chip in 2017 during his master’s thesis at the American University Beirut.
