I am a senior research associate and a principal investigator of an Ambizione grant by the Swiss National Science Foundation at the University of Zurich. My group's work focuses on planet- and satellite formation, especially on the circumplanetary disks. I am also an associate member of the PlanetS collaboration.In 2017, I was selected among the "Forbes 30 under 30 in Science" by the Forbes Magazine. If you are interested in my research, you can check it out at the exhibition "Expedition Solar System" in Focus Terra (Zurich) till the end of June 2019! Press coverage here.
Prior my current appointment, I was an ETH Fellow at the Swiss Federal Institute of Technology in Zurich. I finished my PhD in 2015 in France and did my MS & BS in Hungary. I also worked as a NASA research assistant in 2009-2010 at Space Telescope Science Institute in Baltimore, MD, USA.
With my group, we are doing both theory and observations, including hydrodynamic simulations of planet- & satellite formation and disk evolution, population synthesis, as well as mock observations with radiative transfer. On the observational side, I am leading an ALMA project searching for forming planets and their disks, as well as I am a member of the SPHERE Science Team on direct imaging of protoplanetary disks.

Curriculum Vitae & Publications
Current Areas of my Research
Theory & Numerical Simulations of Planet Formation
In the era where thousands of exoplanets are known, we still have the difficulty to understand how the planets were formed in our Solar System and elsewhere. To seek for answers, I am using and developing radiative hydrodynamical simulations of gas-giants and super-Earths embedded in their natal protoplanetary disks.
Observational Planet Formation
I strongly believe that theory and observations only together can answer how planets are forming. For this prupose, I post-process my hydrodynamic simulations to create synthetic observations with wavelength dependent radiative transfer tools. I also use chemistry codes to provide predictions for observable species, such as the accretion tracer H-alpha. With all the models in hands, I also lead and participate in observational proposals to instruments like ALMA, SPHERE, JWST, etc.
Formation of Satellites
While we have difficulties to understand planet formation, we are completely in the dark about satellite formation around giant planets. Such as our Jupiter and Saturn, many planets thought form a circumplanetary disk during the early stages, where their regular satellites could have formed. I study the properties of this disk via hydrodynamic simulations coupled with population synthesis for satellite formation, in order to understand how the moons in our Solar System came to be, and also to reveal how many potentially habitable exomoons could be out there which we can detect in the near future.
Teaching & Advising
Planet Formation Lecture Script
This lecture script is for the two planet formation lectures within the "Exoplanets" course offered for all physics-, and engineer students (main lecturer of the Exoplanet course: Dr. Sascha Quanz).
Radiative Transfer -- Computational Astrophysics
This is part of the Computational Astrophysics course, offered for applied mathematics and physics students. The main lecturer of the course is Prof. Lucio Mayer.
1) Marco Cilibrasi completed his MS thesis and a paper on satellite population synthesis for Jupiter-analogs. He remains for PhD, which will be about further development of the population synthesis as well as magneto-hydrodynamic simulations of circumplanetary disks.
2) Cassandra Inderbitzi completed her BSc thesis on satellite formation around gravitational instability formed planets with population synthesis. She remains to continue her project to write a paper during her MS.
3) Fabian Binkert is working on his MS thesis of dust-gas hydro simulations and ALMA gaps.
4) Siri Dobler was working on accretion flows around giant planet during her bachelor project.
5) Evert Nasdekin was working on 3D visualization of hydrodynamic simulations with ParaView, as well as writing code to transform the hydrodynamic simulation output files into the VTK format. He finished this as a bachelor project.
6) Honping Deng was working on the inclusion of planetary magnetic field into the circumplanetary disk hydro simulations.
Research Projects for Students
I am currently (2018 fall term) saturated with 5 student projects, unfortunately I cannot supervise more at the moment. If you are interested to do an MS or BS thesis with me in the future (either from ETH or UZH) on the topics of planet-, and satellite formation, do not hesitate to get in touch.
1) Analytical work: converting ionization fractions into H-alpha flux (BSc project with possible extension for MS thesis)
2) Computational work: Satellite formation with population synthesis (for Master Thesis)
3) Computational work: adding ionization and dissociation of hydrogen to the hydrodynamic code, understanding the temperatures and shocks better in the planet vicinity (for Master Thesis)
