Research Associate (Honorary)
Department of Physics,
University of Wisconsin-Madison, Madison, Wisconsin, USA.
I work on projects with theorists and experimentalists in the Quantum Computing in
Silicon group (http://qc.physics.wisc.edu/silicon.html). My contributions to the work
of the group as a Research Associate (2013 - present) culminated in several papers
in top journals like Nature, Nature Communications and Proceedings of the National
Academy of Sciences (nos. 7 - 10 of the Publications list on page 4). The honorary
nature of the position allows me to be based in Singapore with a full-time job, serving
my bond with the Ministry of Education, while working on Physics projects with the
Quantum Computing in Silicon group.

Grades 11-12 equivalent). I also conducted professional development courses for beginning teachers.
Head, Science Talent Programme
Jan 2006 - Dec 2007
Hwa Chong Institution, Singapore.
Hwa Chong is the premier Junior College in Singapore for exceptional students. I
was the Head of the gifted programme for students talented in science, a programme
which I initiated, planned and implemented from scratch. I was in charge of a team of
teachers who put in place a new curricula for such students. I oversaw the curricula
planning, programme evaluation and teacher appraisal aspects of the programme.
