I work in the area of experimental high energy physics, which embarks on the fundamental understanding of the world around us by studying its smallest building blocks and forces that keep these blocks together. In big picture terms, we are trying to understand how the world around us is built and why, including the origin of masses, nature of the mysterious dark matter. To answer these fundamental questions we build large accelerators that smash particles at near the speed of light velocities. We then study the results of such collisions to search for new fundamental particles and study the forces that arise between the particles as they interact. In the past 50 years, nearly major discoveries in particle physics came from collider experiments. These experiments remain to be one of the most promising techniques for studying high-energy physics.
