Postdoctoral reseacher · Globe institute, University of Copenhagen [lizxandra.rivera@sund.ku.dk]

I am a researcher studying the evolution of gas and dust during the early stages of planet formation in protoplanetary disks. My work involves running 2D and 3D hydrodynamical simulations of accretion disks, with a focus on how turbulence driven by hydrodynamic instabilities—such as the Vertical Shear Instability (VSI)—influences dust trapping, pebble transport, and observable gas–dust signatures. I also have experience modeling the chemistry of volatile species, both through time-dependent simulations and post-processing analyses, to investigate the chemical abundances and transport of volatiles in disks around protostars and more evolved Class II systems. I am currently completing my first postdoctoral position at the Globe Institute, University of Copenhagen, working with Dr. Michiel Lambrechts and Dr. Anders Johansen.

On this website, you will find information about my research, publications, talks, and links to data and code (work in progress). Feel free to contact me with any questions or collaboration ideas.

Research

My research aims to advance our understanding of gas-dust dynamics together with thermal evolution of protoplanetary disks.

These advancements have been accomplished step-by-step modifying existing hydrodynamical codes to incorporate more complex physics to make them more suitable to match it closely to observations.

Currently, I am collaborating with postdoc Rio Nakatani (from University of Milan, Italy) implementing a photochemical table in my simulations to correct the gas temperature with photochemical effects.
