Xu Yu graduated from physics department, Nanyang Technological University, Singapore in 2015. He has good knowledge with both nano-particle and optics. Working in Singapore Institute for Neurotechnology (SINAPSE) for more than one year, he is familiar with handling and calibrating photoacoustic microscopic imaging. He has also gained experience in handling animal studies and other laboratory lab skills. During his work in SINAPSE, he used computational modelling to help design hand-held probe of photoacoustic system. His capability in computational work can also be helpful in speeding up the procedure of nano-particle design.
