Welcome
My research combines engineering, data science, ecology, and visualization to measure behavior and physiology of marine animals in a changing climate. For my dissertation, I developed a non-invasive system to record and visualize the sleep patterns of seals at sea published in Science.

Sleep at sea
As increasing human impact coincides with changing ecosystems, it is important to assess how our activities affect animals' natural behavior. Marine mammal sleep had only been studied in the lab. For my dissertation, I combined art, engineering, and biology to develop a system to monitor and visualize the sleep patterns of seals at sea. These tools allow us to learn more about where, when, and how animals sleep at sea so that we can better manage and protect their critical resting habitats.
DESIGN
I designed a surface-mounted system for non-invasive recordings of sleep at sea.

VISUALIZE
I designed a visualization toolbox to allow us to see their behavior alongside their neurological state.

APPLY
I applied the EEG-derived sleep patterns of wild seals to interpret sleep patterns at the population level.

Comparing two futures: modeling the impact of future reef degradation on flooding in Florida
The future loss of reefs will increase flood risk in Florida. The map displays the projected loss in height of reefs (blue) off Miami by 2100 based on current rates of degradation. The 100-year floodplain would increase substantially (orange) based on this reef loss alone. Increases in sea level, storms, population, and development would add further risk.

Modeling the Impact of Future Coral Reef Degradation in Florida
The consequences of projected future reef degradation in Florida. The map identifies where further reef loss will increase risks the greatest. The size of the circles indicates the increase in annual expected economic damages per kilometer of coastline.

Where to restore reefs in Puerto Rico?
Risk Reduction Benefits of Reef Restoration. The full height of the bars indicates current expected flood risk in the 100-year floodplain in Miami, Florida. The blue bar tops indicate the risk that could be reduced with reef restoration; their height and color represent the expected benefit from restoration per 100,000 m2 (hexagon max width = 392 m). Residual risk remains even after reef restoration. The orange line offshore indicates the location of potential reef restoration assessed in the models. The blue polygons offshore represent the extent of current reef habitats.

The Impact of Hurricanes Irma & Maria on Flooding due to Coral Reef Damage
Hurricane Damage to Coral Reefs Increases Future Flood Risk. The blue polygons show the results of NOAA surveys of damages to reefs after Hurricanes Irma and Maria in 2017 around San Juan, Puerto Rico. The white bars indicate expected flood risk in the 100-year floodplain before the hurricanes and the colored bar tops indicate how much risk has increased because of damages to reefs per 50,000 m2 (hexagon max width = 277 m).

The Wave Power Project
This infographic, painted in Procreate and assembled in Adobe Photoshop by Jessie Kendall-Bar, aims to communicate the consequences of reef loss as well as the power of waves. The aim of this work is to communicate to policymakers and stakeholders the consequences of waves and the benefits of reefs. These decision-makers, even those in coastal districts, rarely understand how critical reefs are to preserving lives, livelihoods and property. This work has been presented to top level decision makers at forums with leaders across the US, Pacific and Indian Ocean nations. This included a forum with the 4 atoll nations of the world whose entire existence depends on reefs. The work was funded by the US Department of the Interior and the Kingfisher Foundation.
