Exo-Life Finder (ELF):
We develop a hybrid interferometric telescope to directly image exoplanets and indirectly
map their surfaces using inversions of reflected light curves.
It will alow us to spatially resolve continents, oceans, life colonies and alien civilization
large-scale constructions on nearby exoplanets.

Solar Coronal Magnetic Fields:
We employ linear spectropolarimetry of neutral species and IR forbidden
lines for solar coronal magnetometry. This allows us for the first
time to obtain a full magnetic field vector in the solar corona
which is crucial for monitoring and forecasting space weather.

Hot Molecules in Exoplanets and Protoplanetary Disks:
This project develops several exploratory theoretical and observational aspects
of precision spectropolarimetry for detecting water and other molecules and life
on exoplanets and in the inner part of protoplanetary disks. This is a path towards
finding extraterrestrial life.
Funded by the ERC Advanced Grant HotMol

Innovations in High-Precision Polarimetry:
International collaboration between Germany (KIS), Finland (Turku University) and USA
(Hawaii University) has explored various technologies for high-precision polarimetry.
Three instruments have been designed and built: imaging polarimeter InnoPol,
dual beam polarimeter DIPOL2, and spectropolarimeter BioPol. Their copies are
deployed at various telescopes world-wide.

Starspot Evolution on Active Late-type Stars in the KEPLER Field
The goal of this project is to follow evolution of starspots by
obtaining differential rotation and spot maps
from inversions of continuous light curves obtained with Kepler.
This expands our knowledge on the stellar magnetism and allows to
distinguish stellar and exoplanetary signals.

Molecules in Magnetized Solar and Stellar Atmospheres:
This project has developed fundamentals of the molecular Zeeman, Paschen-Back,
and Hanle effects and their practical applications for studying magnetic fields
on the Sun and cool stars. It helped to solve several long-standing puzzles in
solar and stellar magnetism. We continue employing the developed techniques
for solar, stellar and exoplanetary applications.

Optical support of the NASA/Stanford Gravity Probe B mission:
Our participation in the mission was to provide the best knowledge
on the guide star IM Pegasi in the optics, including radial velocity measurements and Doppler imaging
with spectroscopy as well as photometry and polarimetry.
We have shown that the stellar activity has not affected the GPB results.
This unique campaign made IM Peg one of the best studied star.
Funded by research contracts with SAO (USA) and ETH Zurich grants, Switzerland (2004-2006)

Stellar magnetic fields:
This ongoing project is dedicated to a comprehensive study of magnetic activity on various types of stars
using Doppler imaging, photometric light curve inversions, and polarized molecular band modeling.
Nowadays this has become important in the context of detecting Earth-like planets which is limited
by the stellar activity "noise".
