Dr RAMESH, Sai Sudha, Research Scientist, email: tslssr@nus.edu.sg

Background
I was born in 1981 in Neyveli, India. I graduated with Bachelors in Civil Engineering from the Birla Institute of Technology and Science (BITS, Pilani) in 2003 and was given a direct transfer to M.E (Structural engineering). I obtained my PhD degree in 2009 from the National University of Singapore (NUS) and pursued my postdoctoral research on computational acoustics and model order reduction in the Department of Mechanical Engineering, NUS. I joined Temasek Laboratories in January 2015. Research has been my passion since graduate years and I enjoy developing scientific research codes. Apart from research, I revel in singing/listening to classical music. I enjoy spending weekends with a group of young kids in SSE (Sai Educare), which fosters human values.

Research Interests
