CCAP Curator

Ceci is the CCAP curator. She has worked in the collection since 2007 isolating, characterising, and maintaining different groups of cyanobacteria, microalgae, macroalgae and protozoa. She is responsible for the molecular characterization of CCAP strains and has developed several cryopreservation protocols for both micro- and macroalgae.

Her main interest is the diversity of protists and unveiling some of the mysteries hidden within this extraordinary group.

Contact details:

I am the curator of certain groups of microalgae, seaweeds and protozoa from the Culture Collection of Algae and Protozoa, and my role involves the isolation of new strains, and the morphological and molecular identification of both, newly isolated strains and CCAP holdings. I develop cryopreservation protocols for certain strains to ensure their stability over time. I am also involved in several research projects looking into algae-pathogen interactions.

My main interest is phytoplankton diversity and populations, especially diatoms; and their wider role in the marine environment. I am also very interested in the diversity of algae pathogens and their interactions.
