Evert Nasedkin

As of April 2020, I have begun work as a doctoral student at the Max Planck Institute for Astronomy. I'm working with Paul Molliere and Laura Kreidberg to advance our understanding of exoplanet atmospheres and to improve the tools with which they study them. Working with the ExoGRAVITY team I will be using state-of-the-art instrumentation in order to determine atmospheric properties and evolutionary history, using petitRADTRANS as the starting point for characterization.

I also organize the weekly 'Exocoffee' seminar for the APEx department; if you have an interesting paper you'd like to present, please get in touch!

I completed my Master's of Physics at ETH Zurich in March 2020, under the supervision of Sascha Quanz as a member of the Exoplanets and Habitability group. My thesis involved investigating the impact of instrumental effects from the MIRI MRS on atmospheric parameters retrieved from spectra of Jupiter-like planets and brown dwarfs. I also completed a semester project for Judit Szulagyi on the analysis of hydrodynamic simulation data for circumstellar and circumplanetary disks, and implemented the PACO algorithm as a module in Pynpoint. I completed my Bachelor's of Physics at the University of Waterloo in 2018. During my time at Waterloo, I wrote my bachelor's thesis on the analysis of filaments in interstellar gas clouds and their role in star formation. Through the co-operative education program, I also spent several semesters as a research assistant for various groups, including DEAP-3600, nEXO and ERIS.

Apart from astronomy, I'm an avid musician and photographer, and enjoy travelling around the world to learn about new cultures and people.

Research Interests

I'm mostly interested in exoplanet observation and characterization, trying to learn about atmospheric composition and structure and what this can tell us about the climate and formation history of the planet. I have worked with both ground-based and space based observatories, and hope to continue to push the boundaries of our observational capabilities using next generation telescopes.

In the long term I want to work towards measuring biosignatures in the atmospheres of terrestrial planets to determine prospects for habitability: are we alone out here?
