Brad Lipovsky combines controlled field experiments, dense fiber-optic sensing, and mechanics to test how fluid-driven fractures grow, arrest, and interact with ice, rock, and water.

A mechanics-first research program
Controlled experiments and dense observations test how pressure, elasticity, freezing, heterogeneity, and boundaries govern fracture and friction.

Controlled field experiments test how pressure, elasticity, freezing, heterogeneity, and boundary conditions govern crack growth and arrest.
Explore fracture mechanics02
Glacier beds, ice-shelf rifts, and calving fronts expose how deformation localizes and how failure couples ice, rock, water, and ocean.
Explore ice mechanics03
Dense fiber measurements turn cables into thousands of sensors for observing deformation, fracture, friction, and wave propagation in natural systems.
Explore field observatoriesMechanics in practice
The group designs field tests around specific mechanical questions, then builds the observations and models needed to resolve them.

Controlled field experiments
Experiments combine controlled pressure forcing, dense strain observations, and mechanics to test how elasticity, freezing, heterogeneity, and boundaries govern crack propagation.
See the fracture program
Ice as a natural laboratory
Ice-shelf rifts, calving fronts, and glacier beds reveal how cracks propagate, friction evolves, and failure couples ice to rock and water.
See the ice mechanics program
Enabling infrastructure
Purpose-built and existing cables provide dense measurements of strain, temperature, and wave propagation in systems that are otherwise difficult to instrument.

Leadership means more than publishing results: it means creating shared infrastructure, convening communities, opening data and code, and developing the people who will define what comes next.
Founder of the UW FiberLab, shared infrastructure for field experiments that test deformation, fracture, friction, and wave propagation.
Organizer of “Optical Seismology and the Next Era of Seismic Sensing,” plus sustained conference, working-group, and advisory leadership.
Open data, code, training resources, equipment access, and research translation designed to make new methods useful beyond a single project.
Current highlights
Recent measurements and collaborations that extend field mechanics across scales and settings.
A UW–Nokia Bell Labs demonstration measured strain and wave propagation across multiple spans of the Ocean Observatories Initiative cabled array, extending the scale of field observations.
Seafloor strain measurements resolved how calving drives waves, circulation, and melt—work led by postdoctoral scholar Dominik Gräff with Lipovsky leading the NSF-funded fiber component.
Applied Environmental Intelligence, co-founded by Brad Lipovsky, Stephanie Olinger, and Marine Denolle, applies dense sensing and physics-informed analysis to subsurface deformation and structure.

The Lipovsky research group
Our group pairs high expectations for ethical, reproducible work with kindness, inclusion, candid conversations about credit, sustainable careers, and intellectual ownership for students and postdoctoral scholars.
