S. Chekanov was born in Minsk (Belarus) and received his Ph.D. in experimental physics at Radboud University Nijmegen, The Netherlands. He has more than twenty five years of experience in high-energy particle physics including advanced programming and analysis of large data volumes collected by high-energy experiments operated by major international collaborations. He has written a book and over a hundred professional articles, many of them based on analysis of experimental data from large-scale international experiments, such as LEP (CERN, European Organization for Nuclear Research), HERA (DESY, German Electron Synchrotron) and LHC, the Large Hadron Collider experiment at CERN. Over the past decade he has divided his time between data analysis, developing analysis tools and providing software support for the Midwest data-analysis centre (USA) of the LHC experiment. He is founder of the jWork.ORG community portal for promoting scientific computing for science and education.In 2005 he created a data-analysis software environment, which is presently known as DMelt. Currently, this software is the world's leading open-source program for data analysis, statistics and scientific visualization, incorporating Java packages from more than 100 developers around the world and with thousands of users. Presently, he works at the Argonne National Laboratory (Chicago, USA).
