About me:
I'm a astrophysicist and astrochemist, and currently a staff member at the Max Planck Institute of Astronomy in Heidelberg, Germany. Day by day I sit a front of my laptop and peer into the display, trying to unravel mysteries of formation of our solar system and other extrasolar systems. Major questions that I thrive to answer, using both theoretical predictions and observations at IR/radio frequencies, are 1) how and which simple and complex organic molecules can be synthesized at the verge of planet formation process, 2) analysis and interpretation of molecular emission lines and maps that we observe, and 3) predictions of what we may learn about planet-forming disks with new generation telescopes, such as Atacama Large Millimeter Array (ALMA), NOEMA Interferometer, and the forthcoming James Webb Space Telescope(JWST).

For that, during the last decade I've developed a robust, widely-used gas-grain astrochemistry code "ALCHEMIC" and a number of chemistry analysis and visualization tools written in IDL and Python. In addition to numerical codes, I've developed a number of chemical networks suitable for simulations of chemical evolution, including deuterium fractionation, in various astrophysical environments. Naturally, I couldn't have accomplish all of this without enormous help from my PhD students, which I supervise on a regular basis. Since 2012, I've begin giving lectures at the Heidelberg University, mainly on astrochemistry and molecular astrophysics. Below on my page you can find all the relevant information about my scientific life, publication record, PDFs of the lectures, codes, etc.

Research:
- Chemical evolution of the solar nebula, protoplanetary disks, and star-formation regions
- Isotopic fractionation and grain surface processes
- Interferometric and single-dish observations at (sub-)millimeter wavelengths
Large collaborations and programmes:
- Co-PI in the "Chemistry in Disks" (CID) international consortium to study physics and chemistry of protoplanetary disks
- Co-PI in the PdBI large programme "Fragmentation and disk formation during high-mass star formation"
