Research Interests: Ecology and population structure of uncultured marine protist.

I am doing my PhD in the Marine Science Institute of Barcelona in the Ramon Massana’s group. I am working with protists, in particular with one of the groups of the marine stramenopiles, the MAST-4. This is a heterotrophic flagellate of 2-3 µm of size that is still uncultured. Moreover, MAST-4 is globally distributed and has a significant cell abundance (Massana et al. 2006. EM 8:1515). Lately, I have developed a Q-PCR system to quantify it in marine samples.

Currently I came to the Gabrielle Rocap lab to try to amplify the ITS1 and ITS2 region (Internal Transcribed Spacer) of MAST-4 from environmental DNA to make clone libraries. Then I want to study the microdiversity of the group, if some ecotypes appear, and their relationship with environmental conditions, such as water temperature for example. Furthermore, if is interesting for my samples, I want to develop an automated ribosomal intergenic spacer analysis (ARISA).
