MPI of Animal Behavior

Cecilia Baldoni (Post-Doctoral Researcher)
Animal Cognition; Neurobiology
I am a post-doctoral researcher at the Max Planck Institute of Animal Behavior in Konstanz. I study the link between brain size change and cognition and behavioral flexibility in the common shrew, one of the few mammals which experience the Dehnel phenomenon, a programmed and reversible shrinkage of body and brain size. My interest in Open Science is driven by the troubling frequency of questionable findings and retractions in recent studies. I advocate for reforming academic incentives, believing that promoting transparency in research will lead to more genuine scientific reliability.

MPI for Biogeochemistry

Arina Ivanova (PhD-Student)
Analytical chemistry, mass spectrometry, analysis of transformations of organic matter in the subsurface
I work with dissolved organic matter (DOM) using different mass spectrometric tools. DOM is a very complex mixture of soluble organic molecules of different origin; it represents the most mobile part of OM in the environment, and it reflects interactions between plants, microorganisms, and the medium. I’m interested in 1) developing new mass spectrometric methods for structural description of DOM; 2) fate of DOM in the subsurface: its transformations during the passage through soil to aquifers ,and DOM dynamics in the aquifers.

MPI for Evolutionary Anthropology

Annika Tjuka (Post-Doctoral Researcher)
Linguistics, Psychology
My main goal is to explore linguistic diversity, especially the variations of word meanings across languages. I integrate findings from linguistics and psychology in my research and adopt a computational approach. I received my doctorate with highest honours (summa cum laude) from Friedrich Schiller University Jena in March 2024 and I am working as a postdoctoral researcher at the Max Planck Institute for Evolutionary Anthropology. A major academic career achievement so far is developing a cross-linguistic database, which contains rich information on word properties across 39 languages (https://norare.clld.org). In addition, I have investigated the relationship between word meanings in the semantic domain of the human body, exploring the intricate interplay between language, culture and cognition. The key results of these investigations are reported in a study on body-object colexifications published in Linguistic Typology and a study on body part vocabularies published in Scientific Reports.

Sungbin Lim (PhD-Student)
Evolution of the bacterial translation system
I am a PhD candidate at the Max Planck Institute for Evolutionary Biology, studying the dynamics of bacterial translation traits. My research focuses on programmed ribosomal frameshifting (PRF) in release factor 2 (RF2) and the evolutionary absence of ANN-type tRNAs, by using approaches of experimental evolution, molecular genetics, and phylogenetic analysis. Through these systems, I investigate how traits are maintained, lost, or avoided under certain evolutionary circumstances, and how neutral processes and compensatory evolution contribute to it as well. I aim to expand my research toward the evolution of translation fidelity, fitness landscapes, and evolutionary constraints, while continuing to explore the philosophical aspect of my research as well.

Psycholinguistics, individual differences, language comprehension and production
I’m a postdoctoral researcher at the MPI for Psycholinguistics, where I focus on individual differences in language production and comprehension. My work centers around the development of a battery of linguistic and cognitive tasks for English speakers, which will also be made available as a tool to other researchers. I’m particularly interested in investigating the different pathways individuals may take to understand language and how these covary with other cognitive abilities or processing styles. Additional research interests of mine include probabilistic language processing and usage-based linguistics, and I take a special interest in statistical methods. Before coming to the MPI, I received my Ph.D. from the University of Freiburg in Germany. My undergraduate studies were at the University of North Carolina in Chapel Hill.

Julia Chauvet (PhD-Student)
Psycholinguistics and speech motor control
How do we articulate a thought into a sequence of spoken sounds? My research aims to bring together neurocognitive computational models of lexical access and speech motor control, examining the issues that arise at their interface. By integrating these frameworks into a model of lexical generation, we can uncover several key questions at their intersection. These include: (i) Identifying elements of linguistic planning that are relevant for—and cascade to—motor planning, and understanding their hierarchical relationship. (ii) Determining critical features of the different levels of self-monitoring, the conditions under which they occur, and the interplay between mechanisms of motor control and self-monitoring. I employ theoretical computational work simulates how elements of phonological planning are carried forward from linguistic planning to motor control.

The dispositional and social factors that influence selectivity in prosocial behavior.
My research focuses on the dispositional and social factors that influence selectivity in prosocial behaviour. Particularly, I’m interested in why some individuals are more selective than others in who they are prosocial towards, and whether such individual differences can be explained by personality traits. With this, I am also working on adapting well-established measures of prosocial behavior to capture inter-individual variance in selective prosociality.
