My research has been focused on studying how intracellular trafficking is important for cellular function, in particular for neuronal function. It remains fairly unknown how the regulation of intracellular trafficking is important for synaptic function and dysfunction.
Currently, my major goal is to identify which mechanisms of intracellular trafficking in neurons become impaired with aging thus contributing to Alzheimer’s disease development.

Research Areas

We are currently working to answer the following questions:
1. How does neuronal intracellular trafficking contribute to the degradation of beta-amyloid in neurons?
2. How regulators of intracellular trafficking contribute to beta-amyloid accumulation in neurons?
3. How does cellular aging, the main risk factor for Alzheimer’s disease, contribute to beta-amyloid accumulation in neurons?

To answer these questions we use primary neuronal cultures as cellular model. We image the dynamics of intracellular transport in live cells using photoactivatable live reporters, cellular synchronization techniques and high-resolution spinning disk confocal microscopy, in addition to cell biology and biochemistry techniques.

Postdoctoral Position

anuncio postdoc

A full-time position, initially for 6 months, renewable up to the end of the project is available for a highly motivated post-doc to join a multinational project to set-up a precise model of the human blood brain barrier in the research lab headed by Claudia Almeida. Selection will begin now until 15th of November to start in January 2018 but will continue until the right post-doc is found.

Dr. Claudia Almeida laboratory focuses on the dysfunction of intracellular trafficking in neuronal aging and neurodegenerative diseases. Dr. Almeida is seeking a highly talented and motivated postdoc, preferably with a PhD in neurosciences with expertise in cell biology, to work on the neurobiology part of NAB3, a collaborative project funded by JPND/H2020, aimed at combining different cellular types and organotypic brain slices or neuronal cultures to achieve a more precise in vitro model of the human blood-brain barrier in the Alzheimer’s disease state. The NAB3 project brings together expertise from across the continent and in a range of different fields, including genetic engineering, physiology, neurobiology, neuroanatomy and biochemistry. It is a coordinated effort with partners based in four European countries – France, Germany, Italy, and the Netherlands.
