Undergraduate Research
I had the privilage of acting as a research assistant for the Pacific Undergraduate Research Experience in Mathematics (PURE Math) hosted at the University of Hawai'i Hilo, under the direction of John Little in 2012 and Scott Chapman in 2013. These 8 week summer programs gave promising undergraduates from underrepresented backgrounds the opportunity to experience mathematics research as they worked on open problems in algebra and number theory.
I also served as a research assistant for the San Diego State University Mathematics REU in the summer of 2014, under the direction of Vadim Ponomarenko, and returned in the summer of 2017 in the role of codirector.
My experiences in these REUs have motivated the frequent inclusion of undergraduate projects into my own research.
Undergraduate projects are an important part of my research, and several of my publications have undergraduate coauthors. If you are an undergraduate student and interested in mathematics research experience, please let me know!
