NICS Intern Spotlight—Vijay Koju

Student Simulates Light Transport in Turbid Media

Vijay Koju, a PhD student in computational science at Middle Tennessee State University and originally from Nepal, simulated the behavior of visible light during his summer 2014 internship at the National Institute for Computational Sciences (NICS) this summer.

His mentor was Dwayne John of the NICS high-performance computing User Assistance group. John and Koju collaborated with Dr. Justin Baba, who is a joint faculty associate professor in the departments of Civil and Environmental Engineering and Mechanical Aerospace and Biomedical Engineering (MABE) at the University of Tennessee, Knoxville, and a staff scientist at Oak Ridge National Laboratory.

The project investigated visible light as it backscatters when passed through a medium. Visible light has the potential to be used in the early detection of diseases such as skin cancer.

Says Koju: "The main task was to modify and add new physics to an existing Monte Carlo simulation program for light transport in turbid media such as tissue, et cetera." For more, view the video.

About JICS and NICS: The Joint Institute for Computational Sciences (JICS) was established by the University of Tennessee and Oak Ridge National Laboratory (ORNL) to advance scientific discovery and state-of-the-art engineering, and to further knowledge of computational modeling and simulation. JICS realizes its vision by taking full advantage of petascale-and-beyond computers housed at ORNL and by educating a new generation of scientists and engineers well versed in the application of computational modeling and simulation for solving the most challenging scientific and engineering problems. JICS runs the National Institute for Computational Sciences (NICS), which had the distinction of deploying and managing the Kraken supercomputer. NICS is a leading academic supercomputing center and a major partner in the National Science Foundation's eXtreme Science and Engineering Discovery Environment, known as XSEDE. In November 2012, JICS sited the Beacon system, which set a record for power efficiency and captured the number one position on the Green500 list of the most energy-efficient computers.
