I am often looking for undergraduate students, graduate students and postdoctoral fellows:

  • Graduate Students: If you are interested in joining my team as a MASc, PhD, or a post-doc, please email me your recent CV, transcript, and a paragraph on what particular area of research you are interested in. Software skills in addition to basic knowledge of analytics and optimization methods is required.
  • Undergraduate Students: If you are interested in an undergraduate research experience, please email me your recent CV and transcript. Students are encouraged to apply for USRA and the President's Research Award in case they are eligible.
