We are seeking an enthusiastic and highly motivated PhD student to undertake a 
fully-funded research project investigating the cryopreservation and genetics 
of the nationally significant Cawthron Institute Culture Collection of 
Microalgae. The project will involve working with a multi-disciplinary team of 
environmental, molecular and chemistry researchers at the largest independent 
research institute in New Zealand, the Cawthron Institute, based in Nelson.

The microalgae collection is one of the largest in the Southern Hemisphere and 
includes hundreds of microalgae species from marine and freshwater environments 
in New Zealand, the South Pacific and Antarctica.

The research project involves microalgal culture, cryopreservation and 
molecular techniques. The student will play a key role in the project 
coordinating the various aspects of the research and addressing potential key 
research questions include:
1. Are cyst forms of marine microalgae more resilient to cryopreservation?
2. What new technology is available that could enhance cryopreservation success 
of microalgae? We anticipate that this part of the PhD will be undertaken 
jointly with collaborators in Europe.
3. Do the transcripts of key genes (i.e., those involved in toxin or high value 
compound production) and chemical profiles change after cryo-preservation? This 
section will involve working closely with Cawthron chemistry and biochemistry 
4. Does the environmental source (i.e., tropical vs temperate vs. cold) or 
habitat (benthic vs planktonic) effect cryopreservation success?
5. Are there any key attributes (genetic or structural) that make some 
microalgae more amendable to cryopreservation?
