The INA Foundation is designed to promote education and research on fossil or living nannoplankton through the accumulation, management, and distribution of charitable funds. Through our generous donors, we are able to award Student Travel Grants to partially defer the costs for students attending our INA Meetings and Workshops.

The INA Foundation also sponsors and awards the Katharina von Salis Graduate Research Fellowship to promote and facilitate research on fossil nannoplankton by the upcoming generation of nannofossil workers.

Katharina von Salis Graduate Research Fellowship - 2021 awards

The International Nannoplankton Association (INA) Foundation is pleased to offer two Graduate Research Fellowships honoring Prof. Dr. Katharina von Salis (also known as Katharina Perch-Nielsen) for her many contributions to fossil nannoplankton research and to the INA. The Katharina von Salis Fellowship is intended for students actively seeking advanced degrees researching any aspect of fossil nannoplankton research. There is one award round per year with the call for proposals made in June.

2021 Award winners

We are pleased to announce that the two award winners for 2021 are Janina Falkenberg and Boris Karatsolis.


Janina Falkenberg, 2021 Winner of a Katharina von Salis Graduate Research Fellowship

I am currently a PhD student at the Ruhr-University Bochum (Germany) and working on the use of calcareous nannofossils in archaeology, a field in which they are still poorly known and underused. My research focuses on historic lime-based mortars. These mortars are produced by burning naturally occurring limestones at > 800°C. Due to these high temperatures nannofossils are not expected to be present in the lime binders of mortars. They have, however, been detected in historic mortars.

The main goal of my research project is to establish the use of calcareous nannofossils as a tool for provenance analyses and archaeothermometry of lime-based mortars. By studying different historic buildings, I have already documented that nannofossils are preserved in historic mortars and can be used for provenance analysis. I further want to gain experimental data on how calcareous nannofossils react to increasing temperatures during the burning process. These data will then be applied to historic mortars to reconstruct the burning temperature reached during quicklime production. My studies will thus contribute to the understanding of historic mortar production.


Boris Karatsolis, 2021 Winner of a Katharina von Salis Graduate Research Fellowship

I have been studying nannoplankton and nannofossil assemblages since my bachelor years, moving across host universities that are roughly located in a south to north transect (University of Athens/Milano-Bicocca/Bremen). Loyal to this trip towards higher latitudes, I am currently a PhD student at the Department of Earth Sciences at Uppsala University, Sweden.

Disregarding my “host university transit”, my research has been mainly focused on low-latitude areas and, specifically for my PhD, the NW Australian shelf (IODP Expedition 356). My main scientific interest is understanding late Neogene coccolithophore paleoproductivity and species distribution changes in light of their potential paleoclimatic drivers. Additionally, I am interested in decoupling regional signals of change in coccolith assemblages from global evolutionary patterns. Finally, I aim to investigate an interesting period of elevated paleoproductivity, the late Miocene- early Pliocene biogenic bloom, and compare differences in expression and intensity of this event between lower (e.g the Tropics) and higher latitudes (e.g. north Atlantic-recently drilled IODP Expedition 395 Sites).
