Main achievements
- The best lower limits on half-life for neutrinoless double beta decay of 116Cd
and many other isotopes of Cd, W, Zn, and Gd.
- One of the best upper limits on the Majorana mass of electron neutrino (1.4 eV).
- The first observation of alpha activity of natural tungsten (180W) and europium (151Eu).
- The best limits on the Pauli principle violation in nuclei, on decay of nucleon pairs
into invisible channels, on the flux of low-energy antineutrinos in the Earth,
on heavy neutrino mixing to electron neutrino,
on electromagnetic properties of neutrino (all the limits are obtained
with the CTF detector of the Borexino collaboration).
- Measurement of the flux of low-energy solar neutrinos and of geo-neutrinos in the Borexino detector.
- The best (on the moment of publication) upper limit on the electric charge of photon.
- Limits on mass and coupling constants of hadronic axion emitted
by 7Li and 57Fe in the solar core.
- The investigation of many inorganic crystal scintillators
(molybdates, tungstates, fluorides) as detectors of rare nuclear events and for dark matter search.

Research interests and expertise
My main research areas are in the field of experimental non-accelerator nuclear and particle physics:
development of scintillation detectors for super-low background experiments
(investigations of double beta decay and other rare and forbidden nuclear decays,
dark matter search etc.);
processing of data obtained in these experiments;
Monte-Carlo simulation of these detectors (with Geant4 and other software).
I participated in the following collaborations:
BOREXINO (since 2001);
DAMA (R&D and small experiments);
Kiev-Firenze (since 1998);
NEMO-2 (in 1992-1993);
SuperNEMO (2006-2009).
EURECA (since 2007).
AMORE (since 2009).
Professional awards
Sinelnikov Prize of NASU (2007, together with F.A.Danevich and V.I.Tretyak)
for the cycle of experimental studies of rare processes in nuclear and particle physics.
Teaching activity
Since 2006, I give (together with two colleagues)
a course of astroparticle physics
for graduate students in the Physics Faculty of the Taras Shevchenko National University, Kiev.
I supervised one graduate MSc student and one PhD student (defended in 2007).
