I am a theoretical physicist. For several years I have studied and described inclusive reaction for hadron-hadron collision from a new point of view. It was first publication in this area. I am an expert in Monte Carlo simulations of inelastic particle interactions with particles or nuclei at high energy. The results of my early work were published in the Russian academic review. These publications and my computer code for particle interaction are still widely used in several scientific centers in Russia and USA. At the same time I also worked on the development of quark-gluon picture of particle interactions and on describing Cumulative effect and multiquark states in nuclei, which was experimentally discovered in our Institute. The results were published in leading physics journals and were compiled in my Ph.D. thesis. In 1997 I was promoted to Senior Research Scientist by the Highest Scientific Attestation Commission of the Russian Federation. I was honored with award as one of the best physics at the Laboratory of Computing Technique and Automation (1981) and Laboratory of High Energies (1998) of the Joint Institute for Nuclear Research in Dubna. I have also been an active participant of the WA98, ALICE and CMS international Ion-Ion experiments in Geneva (Switzerland) during 1989-1999. As a collaborator within these experiments, I created several computer programs for numerical simulations of particles and nuclei interactions in the framework of the quark-gluon string model. I took part in work on the ALICE Letter of Intent and project in general. My results and publications in this area were included in final documents of ALICE experiment and still used in research group. I edited the Russian translation of the most widely used code PYTHIA which is nowadays a basic instrument for modeling lepton and exotic processes on future Large Hadron Collider experiments in CERN,Geneva. After invitation in March 1999, I started my work in the Department of Radiology with an important PET/SPECT project. I created and mastered several computer programs for two and three-dimensional image reconstruction which are still successfully used in our scientific researches. The results of this research were published in leading physics and medical journals and several reports were presented at international conferences (IEEE Medical Imaging Conf., 2000-2003 and Soc. of Nuclear Medicine, 2003) In November, 2001 I delivered several lectures to our University students on "Interactions of Radiation with Matter". At present, I am investigating light diffusion in biological tissues by using analytical (Boltzmann-like Radiative Transfer Equation for the wave intensity) and Monte Carlo techniques.I have created a 3D Image reconstruction software for Small Animal Light and Positron Emission Tomography with attenuation and scatter correction. The results of this research were given at SPECT Workshop (Arizona,2004) and conferences (Soc. of Molecular Imaging,2004 ,Biophysical Soc.,2005 and Soc. of Nuclear Medicine,2005), several publications are under preparation. I am author or co-author of over 80 scentific papers published in leading physical and medical journals My research here at UT Southwestern is very interesting and highly relevant to the advance of molecular medicine, particulary in regard to early cancer diagnosis and prognosis. I look forward to continuing participation in this exciting and challenging scientific endeavor.
