Postdoctoral Researcher

Picture
Viktoria Bogantes, Ph.D,  vbogantesaguilar[at]uwf.edu 
Viktoria is originally from Costa Rica. After finishing her undergrad studies at the University of Costa Rica, she moved to Auburn, Alabama for her PhD. During her PhD she focused on studying taxonomy, diversity, and systematics of several groups of annelids, using morphological, molecular and bioinformatic tools. One of her favorite research tasks is doing taxonomic work. She is interested in promoting the use of integrative approaches to identify and describe species and emphasize the importance of museum collections as the main repository of evidence of global biodiversity. Viktoria is very interested in continuing to explore marine biodiversity and contributing to scientific knowledge that can be incorporated with environmental management. At UWF Viktoria will be working on a project that involves the use of environmental DNA to metabarcode reef fish from the Gulf of Mexico.
