       Student Research Opportunities:
  • The WIRLab provides both funded and volunteer opportunities for graduate (JDP, MS thesis, and MS project) and undergraduate students.
  • Black and African-American students, Latinx students, LGBTQ+ students, and students from all groups traditionally under-represented in engineering are especially encouraged to apply.
  • There are a range of scholarships  available at the undergraduate and graduate levels. Visit SDSU's STEM website to find out more about these opportunities. Definitely consider applying!

  • Summer 2021 research opportunity for SDSU students in Brazil: Summer research experience in Brazil to study water and sustainability. Open to students who will be juniors, seniors, or graduate students at SDSU or Cal Poly Pomona by Summer or Fall 2021. More information about last year's research opportunity can be found here: IRES Summer Research in Brazil: Water and Sustainability.
