Princeton geologists solve fossil mystery by creating 3-D ‘virtual tour’ through rock by Liz Fuller-Wright.

With an industrial grinder and a super-high-resolution camera, Princeton geoscientists Adam Maloof and Akshay Mehra can deconstruct rock samples and create three-dimensional digital versions that scientists can look at from any angle. In addition, they have developed software that allows the computer to segment images and isolate objects without human bias.

Paper on Cloudina published in PNAS

February 26, 2018

The first paper from the Princeton Grinder Lab was just published in the Proceedings of the National Academy of Sciences. In Multiscale approach reveals that Cloudina aggregates are detritus and not in situ reef constructions, Akshay Mehra and Adam Maloof leveraged GIRI to produce the first-ever three dimensional reconstructions of Cloudina aggregates.

Geoscience: Creative Destruction

Fossils, ancient rocks, and rare meteorites millions or billions of years old — these are just some of the items that Adam Maloof, an associate professor of geosciences at Princeton, is looking forward to feeding to an automated industrial-scale machine that methodically, efficiently, and precisely grinds everything to dust.

Stunning 3D Rock Images Revealed in New Lab by Laura Poppick.

A geologist and an architect standing in a lab may sound like the start to a very nerdy joke, but a pair of these professionals have joined together to revolutionize the way scientists study structures, such as fossils, inside rocks.

Our lab was recently featured in the Princeton Geosciences News. Grinding Imaging and Reconstruction Instrument (GIRI).

Thanks to funding from Princeton University and the National Science Foundation, the Geosciences lab that houses GIRI (Grinding Imaging and Reconstruction Instrument) opened in February 2013. The lab is dedicated to the digital reconstruction of objects hidden in solid materials through serial grinding and imaging.
