Andrea Unzueta Martínez is a NSF Postdoctoral Fellow in Peter Girgui’s lab at Harvard University. She received her B.Sc. in Marine Biology from the University of Hawaii at Manoa in 2016 and her Ph.D. in Ecology, Evolution, and Marine Biology from Northeastern University in 2021. Andrea’s research uses molecular biology (e.g. metagenomics, transcriptomics) as well as physiological and geochemical techniques (e.g. absorption spectroscopy) to address questions about the contribution of microbial communities to the physiology and ecology of marine animals. On the R/V Falkor(Too) cruise to the Western Galapagos Rift, Andrea will be investigating whether deep-sea mussel microbial communities can play a role in regulating carbonate chemistry at the site of shell formation.
