Every year, the Hector Fellow Academy supports several doctoral positions for promising young scientists from all over the world. Under the supervision of a Hector Fellow, they will work on their innovative doctoral projects over a period of three years. In addition to financing their positions, they receive additional research funding from the Academy and take part in further training events.

The following projects are currently supported:

Temporal and spatial microbial dynamics in the Arctic Ocean

Magda Car­dozo Mino – Hector Fellow Antje Boetius

The project investigates composition and function of microbial communities in Fram Strait, the major gateway between the Arctic and the Atlantic Oceans, and how these are linked with environmental conditions. A series of cutting-edge, molecular approaches are applied to assess microbial functional capacities, community composition and their temporal variation in a region under special threat by climate change. The project is supervised by Hector Fellow Antje Boetius. More ...

Photocatalysis and Transition-Metal-Catalyzed Reactions of Furane-Derivatives

Daniel Eppel  – Hector Fellow A. Stephen K. Hashmi

Fossil resources are increasingly depleted. They have to be replaced as quickly as possible by renewable raw materials, so that a slow transition to a new and modern production of „platform chemicals“ can take place. More ...

Towards Understanding the Genetic Basis of Appetitive Aggressive Behavior

Jan Gerwin – Hector Fellow Axel Meyer

Aggressive behavior can be of two distinct origins: (1) reactive aggression, as a response to threatening or dangerous situations and (2) appetitive aggression, that is motivated by intrinsic factors, for example positive feelings through the exertion of violence. More ...

Fermionic Quantum Gas Microscope

Joannis Koepsell – Hector Fellow Immanuel Bloch

A rich variety of phenomena in solid state systems such as quantum magnetism or high temperature superconductivity still pose open questions on parts of their microscopic explanation. Due to the complexity of these systems, the underlying quantum many-body dynamics is often not accessible to computational simulation. More ...

Unveiling the Galactic History with Pulsating Variable Stars

Gustavo Medina Toledo – Hector Fellow Eva Grebel

This project aims to explore the use of young and old pulsating variable stars to improve our current understanding of the Milky Way. This will be achieved by performing a novel study of the kinematics, ages and chemical compositions of Cepheids and RR Lyrae stars which, in spite of being archetypes of different stellar populations, represent key tracers of the recent star formation and assembly history of the Galaxy. More ...

Bank Structuring in Urban Environments through Micro Groins

Andreas Müller – Hector Fellow Franz Nestmann

The European Water Framework Directive requires that all waterbodies achieve a good ecological status until 2027. In urban environments the restricted spatial conditions and different interests cause problems in river restoration. More ...

Influence of and Climate Change Landuse Changes on Hydrological Variations of Meso-scale Semi-Arid River Basin

Phoebe Pauline Onjira - Hector Fellow Franz Nestmann

Increased anthropogenic activities and climate change are causing a global shift in patterns of water fluxes. Semi-arid river basins are characterized by more water stresses, extreme and sporadic climatic events, and have been projected to worsen in many regions under the influence of climate change. More ...

Sensitive period plasticity and functional recovery after sight restoration

Rashi Pant - Hector Fellow Brigitte Röder

Visual experience during a sensitive period is crucial for the normal development of the brain. Individuals who are treated for congenital cataracts more than a few weeks from birth suffer from low visual acuity as well as specific deficits (such as impaired face processing). This project investigates the possible mechanisms that mediate this sensitive period, by non-invasively assessing brain structure and function in congenitally and developmentally visually deprived individuals. More ...

RR Lyrae stars as tracers of substructure and Galactic archaeology

Zdenek Prudil - Hector Fellow Eva Grebel

Galactic archaeology uses stars as fossils to study the evolutionary history of galaxies like our own Milky Way. Cosmological simulations suggest that larger galaxies were partially formed by accreting smaller dwarf galaxies. Such merger events should leave observable signatures in the form of star streams, but empirical constraints on the times, numbers, and importance of such mergers are still missing. More ...

Towards Topological Many-Body Physics Using State-Dependent Optical Lattices

Hendrik von Raven – Hector Fellow Immanuel Bloch

In modern condensed matter physics topology plays a fundamental role in the classification of phases of matter. A prominent example is the quantum Hall effect discovered in two-dimensional electron gases under extreme conditions. Quantum Hall insulators are isolating in the bulk, but exhibit conducting edge states, which results in a quantised Hall conductance. More ...

Mechanisms of Reproductive Isolation During Rapid Speciation

Sina Rometsch – Hector Fellow Axel Meyer

Reproductive isolation, the ceased exchange of genetic material, is crucial for the divergence of populations into distinct species. This is commonly facilitated by an extrinsic physical barrier, but rarely it can also occur devoid of such barriers. Whether speciation proceeds by the same or different reproductive isolation mechanisms under these two geographic scenarios remains a matter of debate. We aim to contribute to this fundamental question in biology by taking advantage of a model system of speciation: the Midas cichlid fishes. More ...

Accommodation Behavior and Ciliary Muscle Activity in Myopia

Sandra Wagner – Hector Fellow Eberhart Zrenner

Prevalence of myopia (shortsightedness) increases considerably in industrialized countries. The mechanisms behind this development need to be fully understood in order to arrive at prevention. A well-founded hypothesis for myopia development is based on the underaccommodation during near-vision activities (lag of accommodation) which could trigger axial eye elongation. More ...

1,3-Diketon Based Ligands for Transition Metal Catalysis

Jonas Wunsch – Hector Fellow A. Stephen K. Hashmi

The development of catalysts to increase the chemical efficiency or to find completely new chemical reactions has found great interest. For this a wide variety of ligands are needed.
The doctoral is supervised by Hector Fellow A. Stephen K. Hashmi and aims at developing new ligands that are based on the formal double deprotonation of 1,3-diketones and thereby enlarging the chemical space of known ligands. For this new synthetic methods have to be found and the obtained ligands have to be tested and characterised. More ...

Epigenetic Underlying of Appetitive Aggression

Anja Zeller – Hector Fellow Thomas Elbert

Aggression can be distinguished in a reactive form, which is a protective response to an acute threat and an instrumental form, which is goal directed. Appetitive aggression is a sub form of instrumental aggression, which is defined by the experience of lust when perpetrating violence.

So far, the latter has been only assessed through self-report. The doctoral project under supervision of Prof. Thomas Elbert intends to create an objective, epigenetic marker for appetitive aggression. More ...
