Rosenberg lab at Stanford University

Undergraduate research

Undergraduates have made substantial contributions to the research of the lab, and several undergraduates have led or contributed to published research. Research opportunities have included assistance on ongoing projects in the lab under the guidance of a graduate student or postdoc, as well as independent projects typically focused around a specific mathematical problem (or occasionally, data analysis). Undergraduate research experiences have ranged from intense efforts over a single academic term or summer to longer experiences that enable students to participate more substantially in the life of the lab.

Interested students are expected to have experience and interest in one or more areas of quantitative science, such as mathematics, physics, statistics, or computer science, as well as in areas of biology such as evolutionary biology, human biology, biological anthropology, or other related fields. Undergraduates at all levels have been part of the lab.

Stanford programs through which students have conducted summer research in the lab include B-SURP (Biology), SURIM (Mathematics), SURP-Stats (Data Science), and USRP (Bio-X).
