Hélène Choquet, PhD, has been a staff scientist at the Kaiser Permanente Northern California Division of Research since 2016. Her research interests are in human genetics, with a focus on identifying genetic factors which influence complex diseases and their treatments. Dr. Choquet received doctoral training in human genetics at the Lille 2 University of Health and Law in France, and postdoctoral training at the University of California, San Francisco (UCSF). During her postdoctoral research fellowship at UCSF, she was the principal investigator of an American Heart Association award.

Studies

Genetic Etiology of Abdominal Hernia Susceptibility

The objective of this project is to investigate the genetic mechanisms that drive the development of abdominal hernias. This study has three major aims: 1) to investigate the shared and individual genetic risks of different types of abdominal hernia, 2) to examine the genetic risk factors underlying recurrence of hernias in individual patients, and 3) to investigate the genetic pathways and biological mechanisms through which abdominal hernia risk loci act.

The Role of Refractive Error in the Etiology of Glaucoma

The specific aims of this study are to: 1) Determine whether refractive error predicts the development of glaucoma due to direct effects or shared etiology, or both, by conducting a series of genetic analyses of the two conditions; and 2) Determine the contribution of refractive error (myopia) and relevant biological pathways in the development of glaucomatous neurodegeneration.
