Characterizing the diet of the yellowtail parrotfish with DNA metabarcoding 

Funded by NSF, this project uses the genetic technique of DNA metabarcoding to assess and characterize the gut contents of yellowtail parrotfish. This study will give us a better idea of the exact items that this parrotfish species consumes. This project is in collaboration with the University of the Virgin Islands.

Investigating the use of recycled glass sand for coral reef restoration


Sponsored by the local brewery, Medalla, our team is working to establish a sustainable solution to the glass bottle waste issue on the island by turning it into useable sand to incorporate into coral reef restoration. This exciting project will plant 400 coral fragments and observe their growth over the course of one year to test the suitability of using the recycled glass sand for this type of restoration purpose. Read more about it here.

Setting the baseline for a marine debris-free Puerto Rico


Funded by NOAA's Marine Debris Program as part of the Biden-Harris Bipartisan Infrastructure Law, this project will remove 70 abandoned derelict vessels (ADV) from around the island. We will also develop a coordination strategy between agencies to help facilitate a faster response to these issues. We will also be leading several outreach initiatives to educate about ADV prevention.
