The purpose of this undergraduate research training program is to encourage promising students from all disciplines to consider research careers that are broadly related to the cardiovascular and cerebrovascular areas. Students are assigned to leading biomedical research laboratories in California, Nevada or Utah for a ten-week period during the summer to work under the direct supervision of experienced scientists. The projects students work on range from basic molecular research to direct physiological studies. Examples include signal transduction, gene expression, vascular wall biology, ion transport and cellular physiology. Some opportunities for participation in more clinical investigations are also available.
