The Future of Precision Oncology Starts Here

Cancer is a complex disease involving diverse cell types. Yet today’s diagnostics blur that diversity, leaving clinicians and pharma without the clarity needed to guide treatments or trials effectively.

At One Biosciences, we are transforming cancer care by bringing AI-powered single-cell analysis into clinical practice to turn routine biopsies into clear reports that deliver clear insights in less than two weeks.

Our Vision

To make clinical-grade single-cell analysis the global standard in oncology and to transform every biopsy into actionable insights, every decision into precision, and every patient outcome into progress.

Our Story

In 2017 at Institut Curie, we set out to probe tumor heterogeneity using single-cell methods and quickly hit a wall. Microfluidic workflows built for large fresh samples failed on real life patient biopsies, where input is limited and nuclei clump and stick. We were wasting precious material, even on our custom microfluidic station. Meeting Magali Richard and David Schilansky at Home Biosciences sharpened the vision: make single-cell work on real clinical samples, not just in research lab conditions.

In 2020 we created One Biosciences to turn that proof-it-can-work into a platform that delivers high-quality single-cell profiling across tumor types from clinical samples, so clinicians can grasp the heterogeneity that actually drives cancer.

Leadership Team

Our team combines deep oncology expertise, proven biotech leadership and AI innovation.

Dr. Vincent Miller is a world-expert in lung cancer and clinical trial design and interpretation. His role in collaborative research was critical to identifying certain EGFR mutations as the molecular basis of sensitivity and resistance to first-generation EGFR TKIs. Dr. Miller has previously served as Physician-in-Chief at EQRx and prior to that served as Chief Medical Officer at Foundation Medicine. Before joining the Foundation, Dr. Miller dedicated over 20 years to cancer patient care and research at Memorial Sloan Kettering Cancer Center. Among his many accolades, Dr. Miller received the American Cancer Society Clinical Oncology Career Development Award. He joined One’s board in March 2024.

Céline Vallot, PhD

CO-Founder and CSO

Céline Vallot is the head of the Dynamics of Epigenetic Plasticity group at Institut Curie (UMR3244/Translational Department). She joined the Translational Department of IC as a junior group leader in 2017 and is an expert in multi-omics data analysis and epigenetic regulation. She got awarded an ATIP-Avenir grant in 2017, the Bronze Medal of the CNRS in 2018, and the Prix Olga Sain in 2019. Her lab investigates the dynamics of acquisition of chromatin features in cancer cells in vivo and in vitro combining cancer biology to single-cell microfluidics and data mining. Her group has recently co-developed means to analyze the epigenome of cancer cells at single-cell resolution and revealed the heterogeneity of chromatin states within breast tumors. With her group, she has created a series of tools for single-cell data analysis. She has co-founded the single-cell facility of the IC. Céline also holds a MS from Ecole Polytechnique, Paris.

Juliette Bertorello

Head of Wetlab

Juliette Bertorello holds a PhD in Molecular Biology from Paul Sabatier University (Toulouse). She conducted her doctoral research at the Toulouse Cancer Research Center on mechanisms of glioblastoma resistance, particularly the role of RNA translation and DNA repair proteins in regulating RNA metabolism. She later joined Institut Curie as an R&D engineer, where she developed single-cell protocols and contributed to establishing the first One Biosciences laboratory. At One Biosciences, she leads the laboratory team and oversees the development, optimization, and automation of protocols for generating single-cell, single-nuclei, and multi-omics data. She is notably co-author of a publication in NAR Cancer on translational reprogramming in glioblastoma.

Lars Jorgensen

Head of Data

Lars Jorgensen has more than 20 years of international experience in bioinformatics, data science, and large-scale genomic infrastructures. He previously served as Senior Director, Data Science & IT at DNA Script, where he oversaw all Data Science, Bioinformatics, and IT activities, defined the AI strategy (including generative models and LLMs), and led data governance in a regulated environment. Earlier in his career, he led genomic computing activities at the Ontario Institute for Cancer Research (Canada), heading multidisciplinary teams responsible for multi-petabyte sequencing infrastructures and clinical oncology analyses.
