Giselle Hepker

Financial Analyst, Laser Interferometer Gravitational Observatory

Giselle Hepker is the Laser Interferometer Gravitational Observatory (LIGO) Lab Financial Analyst. She earned her Bachelor’s degree in Business with an emphasis in Accounting and Finance from Walla Walla University in 2009, and is currently working on a MBA with a specialization in Project Management from the Florida Institute of Technology. Since 2015 when she started working for LIGO, Giselle has implemented new budgeting software (BudgetPak); developed processes to merge data from the Caltech accounting system, the MIT accounting system, and BudgetPak; and created easy-to-update monthly financial statements that can be rolled up at the highest level in multiple ways (including NSF 1030 categories), or drilled down all the way to individual transactional details. She has led budget managers through the task of bottom-up budget estimating for Fiscal Years (FY) 2016-2018, and developed a spreadsheet to quickly and easily calculate line items for NSF 1030 forms. In 2017, she helped LIGO Lab Business Manager Hannah Hansen design and manage the building of FY2019-2023 budgets for proposal submission to the NSF, including converting a functional WBS structure to an activities-based structure, developing and writing the Cost-Estimating Plan using GAO guidelines, developing Basis of Estimate templates that adhere to NSF Large Facilities Manual (LFM) guidelines, and helping budget managers build their bottom-up budget estimates to build a well-documented, comprehensive, accurate, and credible budget for FY2019-2023.
