Sara Pacheco

A fifth-year student in the Pathology Graduate Program at Brown University, Sara. Pacheco is a student leader with growing expertise in bioinformatics. Working in Brown’s Superfund Research Program, Pacheco aims to identify sperm biomarkers of environmental chemical exposure, with the ultimate goal of improving diagnosis and management of male infertility.


In both human sperm and sperm from rat models exposed to Superfund chemicals, Pacheco performs genome-wide analyses to identify changes in sperm that are associated with low sperm motility. In 2011, she demonstrated her promise as a scientist with publication of a significant paper describing her work in the journal PLoS One.


Pacheco has an intense interest in bioinformatics and working with large datasets. In her work, she employs multiple array techniques for high-throughput screening of her samples, including DNA methylation arrays, messenger RNA arrays, and microRNA arrays.


Pacheco has mentored numerous students in the Pathobiology Graduate Program and has sought leadership positions in national societies. She is the student representative to the Council for the American Society of Andrology and participates regularly in their Women in Science events.
