Bhaya Lab Members

  • Victoria Calatrava Porras (Postdoctoral Fellow)

    My name is Victoria (Vickie) and I received my Ph.D. in Biochemistry and Molecular Biology (2018) from the University of Cordoba (Spain) in the lab of Profs. Aurora Galvan and Emilio Fernandez. My research focused on the assimilation of nitrogen by algae using the model microalga Chlamydomonas reinhardtii, as well as revealing insights of a new mutualistic interaction between this alga and the plant-benefiting bacteria Methylobacterium spp. that allows the alga to thrive under nitrogen limitation. I continued to investigate this algal-bacterial symbiosis as a postdoc fellow in the same lab until I joined Carnegie in 2020. As a postdoc in Profs. Arthur Grossman and Devaki Bhaya’s labs, I am currently investigating a more intimate symbiotic interaction between the amoeba Paulinella and its cyanobacterial endosymbiont to gain insights into the origin and evolution of photosynthetic organelles. Outside of the lab I enjoy outdoor activities, live music, brewing beer and kombucha, and traveling.


  • Frederick De St Pierre Bunbury (Postdoctoral Fellow)

    I started as a PostDoctoral researcher in Arthur Grossman and Devaki Bhaya’s lab in 2019 to study the microbial communities found in the hot springs of Yellowstone National Park. Prior to this, I did my undergraduate studies in Plant Biology at Cambridge University and continued with a PhD in Alison Smith’s lab, where I focused on mutualistic interactions between algae and bacteria centered around the exchange of vitamin B12. I’m currently working on better understanding how Cyanobacteria and Chloroflexi found in hot spring mats interact physically, move cooperatively and build biofilm structure, as well as how they interact chemically through nutrient exchange.
