Alex graduated from Cornell University with a B.S. in Biological Sciences and Statistical Science in 2014. As an undergraduate, he studied with Dr. Charles Aquadro in the population genetics of genes associated with fertility in Drosophila, and the effects of their bacterial symbiont, Wolbachia, which alter the reproduction of their hosts. He was also a part of Cornell's 2013 iGEM team, which was inspired by biodegradable fungal alternatives to Styrofoam to create a synthetic biology toolkit for basidiomycota. He is a Genetics graduate student in the Parham lab and the Bustamante lab. Since his work with Drosophila and Wolbachia, he has been interested in host-pathogen coevolution. He is currently studying the evolution of the MHC system in primates, as well as human HLA diversity and ancestry.

Armin graduated from Harvard University with a B.A. in Physics and Mathematics in 2013. As an undergraduate, he was interested in statistical mechanics and condensed matter and he worked in a high-pressure-physics laboratory. At Stanford, he is a graduate student in Physics in the Bustamante laboratory, and he is interested in developing statistical models for genetics and bioinformatic applications as well as using machine learning and signal processing to improve the bioinformatic pipelines.

Jessica received her B.S. in Cell and Molecular Biology and M.s in Bioinformatics from San Diego State University in 2011 and 2013 respectively. During her masters and after, she worked for a biotech company developing noninvasive prenatal diagnostics before joining the Stanford Biomedical Informatics PhD program in 2014.  She is currently a student in both the Bustamante and Ashley laboratories. Her work and interests include algorithm development and using statistical and machine learning-based methods in population genetics and mobile health data obtained from wearable devices.
