Empowering scientists to develop better medicines through deeper understanding of disease biology.

About Bifrost

Two kinds of systems biology have had a big impact on health. One provides great depth in terms of dynamics and spatial organization by directly observing live cells under the microscope. The other achieves great breadth through genome-scale perturbations and measurements.

Bifrost bridges the two, and also pushes the limits of both – imaging pooled libraries of hundreds of millions of cells with super-resolution and then genotyping each one.”

Our Story

Bifrost (biv-rost)

Noun. Norse Mythology.

The rainbow bridge of the gods
from Asgard, their home
to Midgard, the earth.

 

 

 

Adapting this concept to cell biology, Bifrost Biosystems aims to power efficient discoveries by optically linking deep, multiparameter single-cell phenotypes to related genes – an optical bridge to better understanding of biology.

How it began

Bifrost is a 2021 spinout from the Paulsson Lab at Harvard Medical School as part of a Defense Advanced Research Projects Agency (DARPA)-sponsored program, the Embedded Entrepreneur Initiative (EEI), aimed at translating innovative technologies from academia. Additional optical pooled screening expertise from the Elf Lab at Uppsala University in Sweden, the Church Lab at HMS and the Blainey Lab at the Broad Institute of MIT/Harvard has strengthened the technological depth and know-how of Bifrost. In late 2023, Bifrost was named in a major Advanced Research Projects Agency for Health (ARPA-H) program grant as the subcontractor responsible for delivering the core optical pooled screening instrumentation for the larger program.

Today, Bifrost continues its mission to democratize access to optical-pooled-screening technology as the tool for unlocking previously inaccessible understanding of complex biological pathways and processes.

Johan Paulsson, PhD


A leading researcher in single-cell dynamics, especially in method development and mathematical theory for stochastic processes.
Johan Paulsson is a Professor of Systems Biology at Harvard University. His lab works on dynamic processes in single cells, combining mathematical theory for stochastic processes, microfluidics, microscopy and new biochemical assays. Dr. Paulsson earned his PhD from Uppsala University, Sweden, on theory for stochastic chemistry, and was a Lewis-Thomas Fellow at Princeton University before becoming a tenured faculty member in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge. He joined Harvard in 2005, where he also serves as the founding faculty Director for the HMS microfabrication facility and for Theory in Biology.
Paul Blainey

Paul Blainey, PhD


Pioneering the integration of molecular, optical, microfluidic and computational technologies to solve pressing unmet research and medical needs
Paul Blainey is a core member of the Broad Institute of MIT and Harvard and an associate professor in the Department of Biological Engineering at MIT. An expert in microanalysis systems for studies of individual molecules and cells, his group develops and translates microfluidic, imaging, genomic, and computational approaches to create and share scalable solutions to major challenges in the life sciences and biomedicine. Dr. Blainey holds a BS in chemistry and BA in mathematics from the University of Washington, Seattle. He earned a PhD in physical chemistry from Harvard University and completed postdoctoral research at Stanford University.
Johan Elf

Johan Elf, PhD


A creative inventor of experimental methods and computational tools to study life at the molecular level
Johan Elf is a professor of physical biology at the Department of Cell and Molecular Biology at Uppsala University. A pioneer in single-molecule kinetics investigations in living bacterial cells, Elf is known for his creativity in inventing new experimental methods and computational tools to study life at the molecular level. The Elf group works across the boundaries of the traditional scientific disciplines to address fundamental biological questions related to gene expression, chromosome structure, and the bacterial cell cycle. Dr. Elf earned his Ph.D. in Molecular Biotechnology from Uppsala University, where he studied the theoretical aspects of metabolic fluxes in E. coli with Måns Ehrenberg. He then completed postdoctoral research at Harvard in the laboratory of Sunny Xie, where he pioneered the use of single-molecule fluorescence microscopy to measure in vivo kinetics. Since 2016, Elf has been a member of the Swedish Royal Academy of Sciences, where he also serves on the board. He is the recipient of several prestigious research awards, including the Gustafsson Prize in 2010 and the Norblad-Ekstrand medal in 2021.
George Church

George Church, PhD


Geneticist, molecular engineer, chemist, serial entrepreneur and pioneer in personal genomics and synthetic biology
George Church is Professor of Genetics and Director of PersonalGenomes.org, which provides the world’s only open-access information on human Genomic, Environmental & Trait data (GET). His 1984 Harvard PhD included the first methods for direct genome sequencing, molecular multiplexing & barcoding. These led to the first genome sequence (pathogen, Helicobacter pylori) in 1994. His innovations have contributed to nearly all “next generation” DNA sequencing methods and companies (CGI-BGI, Life, Illumina, Nanopore). This plus his lab’s work on chip-DNA-synthesis, gene editing and stem cell engineering resulted in founding additional application-based companies spanning fields of medical diagnostics (Knome/PierianDx, Alacris, Nebula, Veritas) & synthetic biology/therapeutics (AbVitro/Juno, Gen9/enEvolv/Zymergen/Warpdrive/Gingko, Editas, Egenesis). He has also pioneered new privacy, biosafety, ELSI, environmental & biosecurity policies. He was director of an IARPA BRAIN Project and 3 NIH Centers for Excellence in Genomic Science (2004-2020). His honors include election to NAS & NAE & Franklin Bower Laureate for Achievement in Science. He has coauthored 650 papers, 156 patent publications & a book (Regenesis).
