Vladimir Paar (born 1942 in Zagreb, Croatia), graduated in theoretical physics from the University of Zagreb, Faculty of Science (1965) and received PhD in theoretical nuclear physics (1971). In 1976 he was promoted to professor of physics at Faculty of Science, University of Zagreb. He was teaching undergraduate and graduate courses in physics, biophysics and bioinformatics, and was mentor of 15 PhD theses. Since 2012 he is professor emeritus at University of Zagreb.
In 1992 Paar was elected as full member of Croatian National Academy of Sciences and Arts (HAZU).
As postdoc, guest scientist or guest professor Paar visited a number of foreign institutions (Niels Bohr Institute, Copenhagen; Natuurkundig Laboratorium, Amsterdam; Ludwig Maximilian Universität, München; Johann Gutenberg Universität, Mainz; KFA Jülich; University of Maryland, College Park; Lawrence Livermore National Laboratory, University of California, Berkeley; CNRS, Orsay; JINR Dubna, Moscow; Universidade Federal do Rio de Janeiro; Yale University) (staying abroad seven years in total).
Paar is author of 229 scientific publications included in Web of Science/Science Citation Index (2771 citations, H-index = 25, January 2014). Also, he is author of 69 publications in scientific books and has three patents (encryption methods). He is also author of school textbooks, as well as books and articles in popularization of science and science education (published in Croatian).
His scientific work covers various scientific fields:
- cluster-vibration model in nuclear physics;
- boson-fermion models of nuclear structure;
- discovery of boson-fermion-fermion model for odd-odd nuclei;
- discovery of "parabolic rule" for odd-odd nuclei;
- nuclear field theory with pairing and vibrational phonons;
- nuclear level density at high energies;
- chaoticity of atomic nuclei;
- nonlinear dynamical systems and deterministic chaos;
- discovery of new method connected with "leaking" of chaos and control of chaos;
- nonlinear model of biological oscillators;
- robotic model with regular and chaotic behavior;
- encryption using chaotic transients;
- statistical methods in clinical medicine;
- computer modeling of fractals in biology, chemistry and geography;
- discovery of two new algorithms (Key String Algorithm – KSA) and Global Repeat Map (GRM) for identification of long repeats and higher order repeats in DNA sequences;
- identification of new long repeats and higher order repeats in human and apes chromosomes;
- discovery of idea of codon like trinucleotides (CLTs) in noncoding DNA sequences.
In last ten years his scientific interest is focused to bioinformatics and computational genomics. At the Croatian Academy of sciences and arts he continues scientific work on this problematics.
