Jen Sporleder, BS, is the Vietnam Era Twin Registry’s (VETR) program manager. She’s managed this closed cohort composed of ~7,000 middle-aged male-male twin pairs since 2005. Originally constructed from military records almost 20 years ago to address questions about the long-term health effects of service in Vietnam, the Registry has evolved into one of the largest national twin registries in the US. The Registry is a resource for genetic epidemiological studies of mental and physical health conditions and as such, Ms. Sporleder manages the use of twins for CATI projects, clinical studies, pilot studies, and secondary data analyses. The Registry also has a DNA repository housed at VA Puget Sound.

Ms. Sporleder’s research experience includes project management of multi-site, database, and women veterans' studies. She is also experienced in tracking database development, management, and programming.

She also provides guidance for ERIC Core staff in human subjects’ protection issues by assisting researchers in interpreting and complying with the myriad of IRB, VA, and federal rules and regulations. In accordance with these guidelines, she assists projects in developing SOPs, policies, and operation manuals.
