Working on Gazebo, a dynamic multi-robot simulator. My project is on integration of dynamics solvers and build a benchmark interface for smart choice of solvers for different simulation scenarios. Based on my research work here: https://grasp.robotics.cs.rpi.edu/bpmd/• Built a standard interface for different solvers to be used on the same Gazebo platform. • Contributed parallel solver results to milestone reports. • Participated in the DRC Final Haptix demo. • Contributed pull requests to Gazebo project default branch.• Learned unit/integration/regression test with Google C++ testing framework. • Familiarized with product release procedure, such as feature freeze, code freeze.

Mainly worked with ticker plant team under Software Infrastructure: • Built a database for ticker plant synchronization status storage worldwide.• Created a request/response service for user to either write or access sync status in the database.• Implemented a user interface for the sync monitor with search, filter and sort features.• Modified the back-end data model to support real-time dynamic update on the UI monitor.

• Numerical Simulations of 3-D flows in different arrays of spheres.• Revision of Ergun correlation according to my simulation results.• Getting familiar with the programming environment in Fortran and C
