I no longer read or respond to most cold emails due to the large amounts of email I receive. There are only three exceptions:

• I already know you or know someone who knows you.
• You are my professional colleague contacting me about work.
• You are a UCSD student or affiliate. (See below for details.)

If you are a UCSD student or affiliate, feel free to email me about anything except:

• Do not email about trying to get into a course or registration issues. Talk to Thanh Maxwell or Quynh Dieu (undergrad advisors), or Ethel Lu (grad advisor).
  • If a course is overbooked and you are trying to get in, our policy is that we must prioritize students who fulfill all of the prerequisites and are already on the waitlist. I encourage you to always look into alternate courses to enroll in.
• If you're in one of my classes, use the course discussion forum (you can send private messages there) instead of email.
• Do not email me about course grades unless there is a data entry error. Each course's syllabus will have grading policies listed on it.

Please read the FAQ before cold-emailing.

Q: How can I get a job in a research lab on campus?

This is the most common question I get from students, especially undergrads. Here are some suggestions:

• Take upper-division courses, project-based courses, or even graduate courses, do well in them, then ask the professor at the end of the term whether there are available opportunities.
• Find any professor's office hours that you're interested in, even if they're outside of your department. Then go visit their office hours and ask for opportunities. Even if they don't have any job openings, they might be able to give you valuable advice.
• Find professors' lab webpages and look for postdocs (postdoctoral researchers), research scientists, research staff, lab technicians, graduate students (Ph.D. or masters students) there; then email them to ask for opportunities. They will be easier to reach than professors.
• You can also directly email professors, but your chances of getting a response are lower. Don't be discouraged if they don't respond; keep trying hard to find new opportunities.
• Look for newly-hired professors (often called assistant professors) since they may be looking to grow their new lab so are more likely to respond to your email.
• Again, be willing to look outside your department for opportunities.
• If any professors are giving special talks or guest lectures on campus, attend and go up to them afterward to ask for relevant opportunities.
• If you have friends who currently work in a research lab, try to get them to introduce you to the relevant graduate students, postdocs, research scientists, or professors. A good referral can be very effective.
