Undergraduate Research Engagement Program (Spring 2016, Fall 2016, Spring 2017, Spring 2018)

The UREProgram at UMass partners advanced undergraduate political science and legal studies majors with faculty for hands-on, one-on-one research experiences. I have supervised over 20 undergraduate students for four different research projects. This involved training and mentoring them across all aspects of the research experience, including: developing research protocols, gathering and coding data, conducting literature reviews, and holding weekly mentoring meetings.
