Ignacio Nunez is a seasoned operator and manufacturing executive with deep expertise in biologics, cell and gene therapies, and complex GMP manufacturing systems. He has spent his career helping organizations translate breakthrough therapies into scalable, reliable operations.
Most recently, Ignacio served as Chief Operating Officer of CellReady, where he led the company's operational expansion in the cell and gene therapy space. He drove large-scale organizational and manufacturing transformations, delivering material reductions in capital expenditure and development timelines while strengthening GMP manufacturing, quality systems, and supply chain performance across collaborations with global biopharma, emerging biotech, academic institutions, investors, and CDMOs/CROs.
Earlier, Ignacio contributed hands-on to the industrialization and commercialization of next-generation therapies, including some of the first FDA-approved cell and gene therapies. He founded BioExcellence to bring operator-led execution to clients—developing high-throughput manufacturing and operational excellence models adopted in the design and optimization of large-scale cell therapy production facilities.
Ignacio holds B.S. and M.Sc. degrees in Chemical Engineering from the University of Granada and is a certified Lean Six Sigma Master Black Belt.



Dr. Talar Tokatlian is an accomplished biotechnology leader with over 15 years of expertise in CAR T cell therapies, nanoparticle vaccines, and biomaterials. She currently serves as the Director of Discovery Research at A2 Biotherapeutics, Inc., where she has spent over eight years advancing innovative, logic-gated cell therapies (Tmod™ platform) for solid tumors. Her career at A2 Bio spans progressive leadership roles, including leading the Adaptive Innovation group which bridges late Discovery Research and Process Development.
Prior to joining industry, Dr. Tokatlian completed a postdoctoral research fellowship at the Massachusetts Institute of Technology (MIT) in the lab of Darrell J. Irvine at the Koch Institute, focusing on nanoparticle design for HIV vaccines. She earned her PhD in Chemical Engineering from UCLA in the lab of Tatiana Segura, specializing in porous hyaluronic acid hydrogels for gene delivery, and holds a BS in Chemical Engineering from UC Berkeley. A frequent speaker at industry symposia, she is a driving force in the Southern California cell and gene therapy ecosystem.



Dr. Sareen is the founding Executive Director and Chief Biomanufacturing Officer of the Cedars-Sinai Biomanufacturing Center (CBC). A visionary leader at the intersection of biology and engineering, he has extensive experience in human iPSC-based platform technologies, GMP biomanufacturing, space medicine, mechanistic drug discovery, and the clinical translation of genetically engineered cell therapies.
As a pioneer in the field, Dr. Sareen leads the CBC, a premier Center of Excellence for cell and gene therapy innovation. He spearheaded the design and construction of a cutting-edge 25,000 SF current Good Manufacturing Practice (cGMP) facility. This "smart" infrastructure houses multiple ISO-certified cleanroom suites and leverages tech-enabled biology to support human IND-enabling clinical trials. Under his leadership, the CBC has established a robust biomanufacturing pipeline that bridges the gap between academic discovery and commercial reality.
Dr. Sareen is driving the next evolution of biomanufacturing by integrating artificial intelligence (AI) and machine learning into the production workflow. His team is building automated, data-driven pipelines that optimize iPSC generation and cell differentiation, ensuring reproducibility and scalability. He led the development of the world’s largest ALS iPSC and motor neuron biorepository (Answer ALS), comprising over 1,200 patient lines (>4,000 clonal iPSCs) distributed globally. Beyond the bench, Dr. Sareen is deeply committed to enterprise formation and the commercialization of science. He established the CBC as a unique Partnership Development Manufacturing Organization (PDMO)—a hybrid model that not only provides cGMP services but actively incubates early-stage companies and fosters new ventures in the cell and gene therapy space.
His research group remains at the forefront of innovation, specializing in the differentiation of stem cells into neurons, vascular endothelium, and organoids. A prolific inventor, Dr. Sareen holds several patents on reprogramming, differentiation, biomanufacturing automation, and immune-evasion platform technologies. By combining modern genetic engineering with AI-enhanced automation, he is building the infrastructure to scale the next generation of "off-the-shelf" therapies, championing symbiotic partnerships between academia and industry to accelerate cures for today’s most intractable diseases.
Hear firsthand from cancer survivor Laurie Adami as she shares her powerful journey of recovery alongside top industry advocates.
Join experts from Cedars-Sinai Medical Center, USC, and A2 Biotherapeutics as they discuss new cellular immunotherapies and hope for solid tumor patients.
Connect with leading scientists from UCLA and USC/CHLA to explore the next generation of manufacturing advancements.
