Mhar Ian Estayan

I am a goal-driven and enthusiastic scientist. My work involves using fundamental physics principles to solve problems in human biology such as physiology. I am highly motivated and inquisitive. I am currently exploring the fields of cardiac dynamics, applied neuroscience, and electrospray ionization instrumentation.
