1. Epic Beaker AP was implemented at Geisinger Medical Center, PA. This laboratory information system

(LIS) solution is projected to help Geisinger Medical Center, PA optimize and manage Anatomic Pathology workflows and leverage a complete patient record to improve experiences for patients. I was among the team of Pathologists tasked to build and tailor the LIS to address the workflow at our laboratory.

2. I was tasked to build the Autopsy workflow and test the LIS. I completed this task successfully.

3. I also built and tested a novel trainee feedback and evaluation platform built into the LIS to assist residents to receive feedback, tracking, and trending the cases they participate in.
