Christina is a pioneer in the fields of synthetic biology and metabolic engineering, where she has over 20 years of experience. As Professor of Bioengineering and Chemical Engineering at Stanford University, her laboratory led the breakthrough research to engineer baker’s yeast to produce valuable plant-based medicines, including the opioids and noscapinoids. Her innovative vision and accomplishments have garnered numerous awards, including the Chan-Zuckerberg Biohub Investigator, NIH Director’s Pioneer Award, Nature’s 10, World Technology Network Award in Biotechnology, and TR35 Award. As CEO of Antheia, she is committed to seeing their breakthrough science used to create a healthier people and planet. Christina earned her BS in Chemical Engineering from USC and her PhD in Chemical Engineering from UC Berkeley.

Christina Smolke, PhD

Co-Founder & CEO

Kristy has over 15 years of experience in the field of synthetic biology, focusing on yeast metabolic engineering for the production of small molecules. She did the founding work on the benzylisoquinoline alkaloid pathway during her graduate studies and gained valuable industry experience at Amyris and Lygos. Kristy is an expert in tool development, high-throughput screening, and host strain and heterologous pathway engineering. She believes that all plant-derived medicines will ultimately be produced using microbial fermentation technology. Kristy earned her B.S. in chemical engineering from Texas A&M University and her Ph.D. from the California Institute of Technology.

Kristy Hawkins, PhD

Co-Founder & CSO

Kate is a former plant biologist turned yeast metabolic engineer. She is passionate about studying the novel and specialized ways that plants make medicines and harnessing this knowledge to deliver new and better therapeutics. As a postdoctoral researcher at Stanford University, she was a part of the breakthrough team to first demonstrate total biosynthesis of opioids and noscapinoids in yeast. Her work now focuses on nature’s catalysts; discovering, improving upon, and ultimately using enzymes to make valuable plant-inspired medicines. Kate earned her BS in Biological Sciences from the University of Auckland, New Zealand, and her PhD at the John Innes Center (University of East Anglia), United Kingdom.

Kate Thodey, PhD

Co-Founder & Director of Enzyme Engineering

Isis is a seasoned yeast engineer with expertise in the production of benzylisoquinoline alkaloids, and now serves as the Vice President of Operations. As a graduate student and postdoctoral researcher at Stanford, she was part of the team that developed platform yeast strains for the production of diverse benzylisoquinoline alkaloids from sugar, and now she leverages her technical training to build processes that keep Antheia running smoothly. Isis earned her BS in Biomedical Engineering at the University of Texas at Austin and her MS and PhD in Bioengineering at Stanford University.
