Biography
Dr. Lim is a co-founder of Xcellbio and is currently leading the company’s effort in the development of an advanced primary cell culture and analytics platform. Focused on technologies that enable therapeutic drug development, Dr. Lim is the inventor of the AVATAR cell control system. This IP protected system allows researchers to study primary cells under a diverse range of microenvironments found in the human body. Applications that utilize discrete pressure and oxygen settings were developed by Dr. Lim’s group to expand rare cell types (circulating tumor cells, cancer stem cells), enhance iPSC differentiation into neurons, and predict CAR-T efficacy utilizing autologous model systems. Dr. Lim received his B.Sc. In Cell Biology from McGill University, and his Ph.D. in Biophysics from The Scripps Research Institute. He conducted his post-doctoral studies at Harvard Medical School and launched Xcellbio while working as a researcher at the Lawrence Berkeley National Laboratory.
