1977-1980. Main achievements in the field of bioorganic compounds

      Studied the reaction kinetics and equilibrium between nucleotides and  hydroxymethyl derivatives of beta-alanine as a perspective reagent for probing DNA structure. Proposed the reaction scheme, product structure, measured equilibrium and kinetic constants.
1980-1983. Main achievements in the field of molecular biophysics
 Studied of the interaction of the non-histone protein HMG1 with DNA of different origin and synthetic DNA matrices of different nucleotide sequence. Developed a micro method of measurement of protein binding constants to DNA by the gel-filtration. Measured binding constants and nucleotide specificity of binding. Described the HMG1-DNA complexes by the thermal melting, thermal profiles of CD spectra, analytical ultracentrifugation, and modified kinetic formaldehyde method.

1984-2015. Main achievements in the field of bioinformatics.
 1) Developed a package of programs for digitizing, storing, picturing and computer treatment of UV adsorption spectra, titration and kinetic curves, elution profiles, thermal melting curves etc.
2) Developed a package of program for the routine analysis of DNA and protein sequences
     (for ISKRA-226).
3) Took part in the development of the All-Union database GENEXPESS of primary
      structures of biopolymers (closest analog is EMBL database)
4) Developed a package of program for the study of some statistical properties of
      DNA sequences mainly the statistics of oligonucleotides, context-dependent
      codon bias, prediction of the protein coding regions, back translation of proteins
      (for ISKRA-226).  In collaboration with M. Borodovsky showed that context-  
      dependence mainly reduce code degeneracy in E. coli.
5)  Developed a package of program for the study of DNA sequences (for IBM PC).

6) Proposed and implemented an accelerated algorithm of dot-matrix calculation, as well as an algorithm of multidimensional dot-matrices.

7)  Developed a method of fast sequence comparison.

8) Developed a Bayesian method of alphoid sequences classification. In collaboration with I. Alexandrov and coworkers, classified alphoid sequences and studied its chromosomal topography, interspersed repeats inhabitation, and proposed a scenario of alphoid sequences origin and evolution. It is shown that subtypes of old alpha-satellite are arranged in concentric manner around living centromere originated during molecular evolution of centromere. 

9) Implemented an advanced version of Exon-Intron Database. Based on this DB is a number of workson the structure and identification of some classes of genes, RNA, introns etc.
