Lina Abi Mosleh, Ph.D.Principal Scientist at Ayass Bioscience and Vice President
Lina is the Vice President and Principal Scientist at Ayass Bioscience, LLC with the responsibility to oversee, manage, and lead daily operations in both the clinical and research laboratories. Prior to joining Ayass Bioscience, her career was focused on basic science research in academic institutions where she served as a faculty member. The opportunity presented at Ayass Bioscience allowed her to utilize her skills and dive into the world of translational research by bridging science to patient care. She is involved in the design, development, and validation of high complexity molecular testing from next generation sequencing to array-based genotyping assays. She is also part of a research team that utilizes nanotechnology for diagnostic applications, identifies and clinically validates new biomarkers for autoimmune disease, and develops aptamers for diagnostic and therapeutic applications in the fields of coagulation, allergy, cancer, and COVID-19.
Ayass Bioscience has been a pioneer in implementing artificial intelligence to predict patient outcome. It started with the development of ‘MoNet’, an advanced biological tool that uses CAI (Cognitive Artificial Intelligence) to collect and analyze data from hundreds of molecular tests conducted on thousands of patients at Ayass Bioscience to identify clinical associations between biomarkers and generate a prediction score for an individual’s risk of thrombosis. Lina had the privilege to be part of that project that opened the door for the development of Machine Learning Models for the prediction of patient outcome as it relates to cancer and metastasis. With data produced at an unprecedented rate, the new direction of Ayass Bioscience is to implement such tools to build models for prediction for better patient outcome in other disciplines of medicine such as immunology as well as in the biomedical research conducted.

Lina earned her Bachelor’s and Master’s in Cell Biology at the American University of Beirut in Lebanon. Upon moving to the U.S., Lina received her Ph.D. in Molecular Genetics and Biochemistry at the University of Texas Southwestern Medical Center at Dallas in the laboratory of Nobel laureates Drs. Michael S. Brown and Joseph L Goldstein.
