Extant life detection using label-free video microscopy in analog aquatic environments Open
The ability of microbial active motion, morphology, and optical properties to serve as biosignatures was investigated by in situ video microscopy in a wide range of extreme field sites where such imaging had not been performed previously. …

Microbial Motility at the Bottom of North America: Digital Holographic Microscopy and Genomic Motility Signatures in Badwater Spring, Death Valley National Park Open
Motility is widely distributed across the tree of life and can be recognized by microscopy regardless of phylogenetic affiliation, biochemical composition, or mechanism. Microscopy has thus been proposed as a potential tool for detection o…

Biogeochemical Responses to Mixing of Glacial Meltwater and Hot Spring Discharge in the Mount St. Helens Crater Open
Environments where geothermal waters and glacier meltwater mix are common on Earth yet little is known about the biogeochemical processes that occur when hot, reduced geothermal water mixes with cold, oxidized glacial meltwater in natural …

Biogeochemical responses to mixing of glacial meltwater and hot spring discharge in the Mount St. Helens crater Open
Analytical measurements of water at the three sampling sites: glacier, hot spring and downstream. Error in measurements (±) represents 1 standard deviation when replicate laboratory measurements were taken. Limit of detection (LoD) was cal…

Linking monitoring and data analysis to predictions and decisions for the range-wide eastern black rail status assessment Open
The US Fish and Wildlife Service (USFWS) has initiated a re-envisioned approach for providing decision makers with the best available science and synthesis of that information, called the Species Status Assessment (SSA), for endangered spe…

Large Data Considerations in Digital Holographic Microscopy Open
Digital holographic microscopy (DHM) is an interferometric technique with several advantages over traditional light microscopy.A hologram is an interference pattern produced by a coherent "reference" beam recombining with an "object" beam …

ELVIS: A Correlated Light-Field and Digital Holographic Microscope for Field and Laboratory Investigations Open
We are developing a unique multi-modal volumetric microscope capable of instantaneous imaging of sample volumes approximately 100-fold larger than those sampled by conventional fluorescence microscopy, with spatial resolution sufficient to…
