Open PhD Position

Interaction of solar light with cloud particle is one of the big unknows in climate science. Yet, accurate information on cloud particle optical properties are needed to evaluate the radiative effect of clouds and to interpret remote sensing observations. In-situ observations of individual cloud particles can help us to establish the link between particle morphology and it's optical properties. Here at KIT we are developing novel instrumentation to experimantally define the optical properties of cloud particles.
We are looking for a new team member who will help us to further develop, characterise and deploy a single particle polar nephelometer for cloud particle research. The work will include implementation of polarisation detection, characterisation of the measurement setup and peforming and analysing first laboratory and field measurements. 
What we offer
  • The possibility to work with one-of-the-kind instruments
  • Chance to participate and plan laboratory experiments in the AIDA cloud chamber and to participate to field work
  • Chance to work independently and realise your own scientific ideas
  • A dynamic team consisting of different nationalities

What we expect

  • Previous experience from working with instrumentation or experience from laboratory work. Experience with instrument development will be advantageous.
  • A Master degree in physics, meteorology, atmospheric sciences or a comparabel field. Experince with optics will be considered as an asset.
  • Ability to work independently and to solve problems
  • Willingness to work in the laboratory and to participate to field campaigns 

The position is a 3-year position for a doctoral student (75%, TV-L E13). Starting date is flexible but no later than by June 2022. To apply for this position, send your application package (cover letter, CV, contact details of two academic referees) per email to the contact below. Application deadline is 30.11.2021.

KIT does not cover relocation for this position.

Open Positions for Master Students

We are always happy to welcome students to work with their Master theses in our group. Right now we are looking students to join the following projects:

Investigation of Ice Crystal Morphology

Atmospheric ice crystals come in a myriad of different shapes. To what shape an ice crystal grows depends on environmental conditions, such as temperature and relative humidity. Laboratory work has shown some quidelines to what habits are expected in which conditions but as we are gaining ever-improving observations of real atmospheric ice crystals - this question should be revisited. Therefore, we invite a Master student to work with our data set of high-resolution stereo-microscopic images of real atmospheric ice crystals gathered from all over the world and to link their morphology to the simultaneously measured environmental conditions.

Photoacoustic Absorption Spectroscopy of Combustion Particles  

Combustion aerosols are affecting both climate and our health. Especially in the Arctic region absorping particles can lead to enhanced melting of snow and accelerate warming. We at KIT are developing novel measurement methods to detect and analyse combustion aerosol particles using photoacoustic method. We are looking for a Master student to work with improving our method and to analyse data from the Arctic region.
