Member of the Telescope Array (TA) international collaboration, which consists of 147 members over 36 institutions from US, Japan, Belgium, Korea, Russia, and Czech Republic. The Telescope Array experiment is the largest cosmic ray observatory in the Northern hemisphere that was built in the desert of Millard county near Delta, UT to detect ultrahigh energy cosmic rays – mysterious energetic particles of extraterrestrial origin. In recent years, exciting discoveries in the cosmic ray energy spectrum, mass composition, and arrival directions were made. Main contributions are:
- Solved difficult problems, scraped data, built histograms, scatter plots, heat maps, graphs, and interpreted trends in the data. Personally authored or was a contributing co-author of at least 40 peer-reviewed and over 110 all publications .
- Wrote over 100,000 lines of production code in C++, Python, Bash, and FORTRAN. Developed, maintained, and executed fitting, reconstruction, and simulation codes on computing clusters. A source code sample can be found on https://github.com/ivanovdmitri.
- Managed a local 50 Tb data server for the University of Utah group. Applied and administered Web, Git, Subversion, and SQL services for the group. Assisted colleagues with statistics and programming questions.
- Mentored graduate and undergraduate students. Produced and maintained the official surface detector spectrum measurement for the Telescope Array collaboration.
- Performed an analysis using joint Telescope Array and Pierre Auger data and was elected twice (1, 2) to present the joint results of the two collaborations at major cosmic ray conferences.
