Present Activities
Our interests encompass a wide range of disciplines, ranging from
understanding of fundamental physico-chemical processes to development of new
tools based on different spectroscopic methods for trace detection and to ex-vivo bone
regeneration.

Vibrationally Promoted Photodissociation Studies. This topic focuses on
one of the most sought after goals in the field of chemical physics, the dream of
selective bond breaking in polyatomic molecules. One of the fascinating schemes that
have been conceived to achieve this goal is that of vibrationally mediated
photodissociation, based on excitation of different skeletal motions of molecules and
their subsequent interaction with photons. To this end we have shown that in some
cases the desired reaction pathway can be preferentially selected, in others the state
distributions can be altered and the nature of vibrationally excited states can be
characterized (in collaboration with Prof. S. Rosenwaks).

Laser-based diagnostics. A great deal of effort is expended these days in
attempt to develop and utilize laser-based diagnostic techniques, owing to the
availability of laser sources with high temporal, spectral and spatial resolution. These
methods purvey high levels of analytical performance characterized by real-time or
nearly real-time capabilities, high selectivity and sensitivity and in situ monitoring.
Therefore, they might be employed for tagging and detection of atmospheric gases
and environmental pollutants, and for forensic and military applications and different
processes including combustion and incineration. In particular, we focus on finding
the spectral signatures, i.e., the “fingerprints” corresponding to nitro compounds
allowing detection of vapor-phase and solid traces of explosives in ambient air (in
collaboration with Prof. S. Rosenwaks).

Ex vivo bone regeneration. This newly and interdisciplinary project
combines principles of cellular-biological and biomimesis processes along with
photonics to explore cell–material-laser irradiation interrelations. We focus on the
development of novel biomatrices of marine origin and ablated biomatrices coated
with calcium carbonate and calcium oxide micro- and nano-sized particles, on the
establishment of a cell-material system for studying in vitro ossification, and on the
determination of the potential for modulating mesenchymal stem cells (MSCs)osteogenic phenotypes. Achieving an understanding of the biomechanism responsible
for enhanced bioactivity and pluripotency of MSCs is assessed by a variety of
physical, chemical and biochemical analyses and will hopefully lead to optimization
of bone scaffolds and to development of new methods of obtaining ex vivo
ossification (in collaboration with Dr. R. Vago and Prof. S. Rosenwaks).
