I am someone who loves the idea of wearing multiple hats and working long hours to complete a goal, thrives in an

innovative environment, eagerly accepts challenges, and finds joy in knowing whats around the corner.

In recent years, my research work on dampers accredited a few remarkable papers, which entitled me the expertise in

mechanical vibrations. My creative approach towards problem solving drove my work with Dr. Oumar Barry to develop a novel

vibration damper. With all the dedication I have towards mechanical engineering, I only aspire to tackle much more complicated

problems.
