High-resolution Optical Imaging for Biology

The central aim of the Danzl lab is to shed light on problems of biological and ultimately also medical relevance using a set of advanced light microscopy tools.

In terms of microscopy, the emphasis is placed on approaches that are not limited in their spatial resolving power by the diffraction of light waves. This diffraction resolution limit entails a maximally achievable resolution of ~200 nm for conventional light microscopy. Diffraction-unlimited methods with a resolution of tens of nanometres allow capturing more details of biological specimens than conventional light microscopy approaches.

Analysing living cells and tissues at high spatial and temporal resolution in a minimally perturbative way poses a significant challenge. To this aim, we engage in the development of novel imaging approaches, building on our expertise both in fundamental physics and in high-resolution imaging. We integrate the imaging with state-of-the-art technologies to manipulate cells and tissues and to label them.

We are an interdisciplinary team of physicists, biologists, and neuroscientists.The life scientists in our group are thus able to directly employ highest performance optical microscopes tailor-made for addressing a specific biological problem while the physicists/engineers in the group enjoy their developments being driven by biological questions and finding immediate application.

Job Openings

We encourage applications from the physics, the biology, and the neuroscience sides (and related disciplines).

Students with a physics, medicine, biology, or neuroscience background interested in pursuing a PhD in our group are invited to apply to the IST graduate school. The graduate school has a strongly interdisciplinary character and is modelled after US graduate schools. Entry is possible with a bachelor or a master degree. All information can be found here.

The PhD admission deadline for the academic year 2019/20 is the 8th of January 2019!

Sample job descriptions for postdocs with a physics or biology background (or related disciplines) can be found here.

Students interested in internships should contact Johann Danzl directly. Please also be aware of the ISTern program during the summer (application deadline 15th of February).
