She has been a RI NSF-EPSCoR Undergraduate Research fellow, as well as a recipient of a AMNH Lerner-Gray Marine Research Grant, and is an AAUS certified diver.

 

Alicia Schickle, Post-Baccalaureate Research TechnicianAlicia Schickle, Post-Baccalaureate Research Technician
Alicia, an RWU alum (Marine Biology/Visual Arts '18), is currently a Rhode Island INBRE-funded post-baccalaureate research fellow in the Sharp Lab. Before joining the Sharp Lab she had a background in ornamental fish husbandry and is now expanding her aquarium husbandry knowledge outside the realm of fish and into microbial ecology of corals and coral spawning. Alicia has recently managed the building of two new recirculating raceway systems to house Astrangia in the lab and helps care for an Astrangia exhibit at the Audubon Society of Rhode Island. She is currently performing experiments on how microplastic-associated microbes impact Astrangia ingestion behavior. When not in the lab, Alicia can be found drawing scientific illustrations or painting surreal works.
