Students

One of the great parts of my job is working with students on research and software development. This page collects information for and about those students.

If you are interested in doing research with me, there are two basic steps:

If you are curious about the kinds of skills you need or will learn in the course of working on research with our group, see my student research skills list.

If you are e-mailing me about our graduate program, please see my e-mail guidance.

For information on applying to graduate school, not just at Boise State, see resources for grad school applications.

Recommended Classes

Most of my students take several of the following classes:

  • CS 533 (Introduction to Data Science, every fall)
  • CS 534 (Machine Learning, every spring)
  • CS 538 (Recommender Systems, odd springs)
  • CS 537 (Introduction to Information Retrieval, odd falls)
  • CS 697 (Advanced Topics in Information Retrieval, even springs)
  • CS 569 (Human Computer Interaction, odd springs)
  • Math 561 (Probability and Statistics)
  • Math 562 (Computational Statistics)

I strongly recommend students interested in working with me take the first information retrieval or recommender systems class they can, and take the CS 533/534 sequence their first year.

Current Openings

Students interested in doing graduate work me and the People and Information Research Team (PIReT) should apply to our M.S. in Computer Science or Ph.D in Computing program. Feel free to e-mail me, but I am not directly involved in admissions and rarely commit to a student until after the admissions process is complete. I also usually don’t know how many funding lines I will have available until the spring, so it’s difficult for me to predict far in advance whether or not I will be able to take a new student in any particular upcoming year.

I am also interested in involving Boise State undergraduate students in our research. Sometimes I have funds myself for paid research opportunities; the university also has several programs that support undergraduate students involved in faculty research, and I am happy to discuss the possibilities of doing an independent study or an opportunity where you get course credit for research.

Current Students
