Emma was born and raised in Beijing, China, and moved to Montreal with family at the age of 15. In June 2025, Emma finished studies at UofT as an undergraduate student with a specialist in Astronomy and Physics. Emma will continue to study at UofT for a MSc degree in Physics. Besides schoolwork, Emma loves acrylic painting and doing hand crafts. Emma enjoys going to work out after SURP and used to be a national second–level athlete in free-style swimming.
What made you decide to participate in SURP?
I gained great experience in AST425 and AST431. Since I will continue my masters study at UofT, I would like to take this opportunity as a smooth transition. I would like to have more instrumental research experience which is what I planned for my masters study, and aligned with my future career plan.
Can you tell us about your research project?
My research project is called “DMD-MOS calibration and On-Sky Testing” (Digital Micro-mirror Device-based Multi-Object Spectrograph). It is a new generation of spectrograph that allows for instantaneous slit mask configuration. Each micro-mirror is able to tilt to two opposite angles so that the light path can be split into either an imaging or spectroscopy channel. Since it can produce multiple slits, we can obtain the spectrum of multiple astronomical objects simultaneously. Compared with older spectrographs, we don’t have to finely adjust the telescope and the slit reconfiguration is instantaneous, which saves on-sky time.
What is your favourite thing about SURP?
I would say beside our great team and great supervisors, my favourite thing is the weekly seminars. It covers many aspects for example: the astronomy frontiers, different astronomy branches, mental health workshop, reading/writing/presentation workshops, etc. I really enjoys these talks and learned a lot from them.
Can you explain how SURP has been different from your undergrad work?
Compared with research courses like AST425 and AST431, SURP is a full-time job. Which means I am able to spend much more time onto one single project. And at the same time, there is no pressure from other courses or gradings. I can have a better focus while making more great progress in the project.
What are your plans for the future?
A short term plan for me is to successfully complete my masters degree with a prof who’s doing telescope/instrumentation relate to astronomy. A longer plan is to apply for PhD and continue my journey in astronomical studies.
