Paul is interested in the atmospheric properties of exoplanets, both close-in (and potentially transiting) or young directly-imaged planets. For his work, he is using a suite of self-written software that can predict the structure and spectra of atmospheres, or retrieve it from observations. In addition he is interested in connecting atmospheric properties, most importantly the atmospheric composition, to models of planet formation. As a direct probe of the chemical abundances of exoplanets atmospheres may hold the key to unravel planet formation pathways. more

Jiao He works in the Origin of Life Laboratory. He carries out laboratory experiments under interstellar relevant conditions to simulate the physical and chemical processes that happen in the ice mantle on dust grains. He studies the formation of complex organic molecules, particularly those of prebiotic interests, either from thermal reactions between simple atomic and molecules or by irradiation of ice mixtures.

Dmitry Semenov is an astrochemistry expert at MPIA who is working mainly
on unraveling chemistry of planet formation. He has developed a number 
robust chemical modeling tools such as ALCHEMIC and MUSCLE to fit 
observations of molecular lines. Dmitry uses world-leading observational facilities 
such as NOEMA and ALMA to peer into rich chemistry of protoplanetary disks.
Last but not least, he is also interested in linking the astrophysical
knowledge with the origin of life studies.

Sierk van Terwisga is a PSF fellow working on the evolution of protoplanetary disks from an observational perspective, and particularly, on how they are affected by their environment. The sensitivity and speed of ALMA make it possible to study these effects, which are difficult to identify in individual disks, by observing large populations of disks in different environments and at different ages. His research combines observations of both the dust and molecular gas in these systems to get new constraints on how planet formation proceeds.

Grigorii is a PhD student working with Prof Henning and Dr Semenov on the thermo-chemical modelling and observation of protoplanetary disks. His project aims to characterize the physical and chemical structure of protoplanetary disks with sub-millimeter ALMA and NOEMA observations, and prepare data processing tools for upcoming JWST.

In my research, I collaborate with Prof Henning and Dr Semenov to investigate the fundamental properties of protoplanetary disks, in particular, their mass and spatial distribution. My interest is to link theoretical models with observational data, combining dust evolution and chemical models with sub-millimeter observations (such as ALMA/NOEMA) and scattered light (such as SPHERE) to provide reliable disk masses, to benchmark the depletion of the CO molecule and to constrain the vertical structure of disks.
