William Fields became a Senior Advisor of Ceres in April 2024.

From 2022-2023, Will served as a White House Infrastructure Implementation Task Force official. He was involved in creating President Biden’s Invest in America agenda, working across the Bipartisan Infrastructure Law and the Inflation Reduction Act. These two infrastructure bills led to over US$1.7 trillion in public sector infrastructure funding. Additionally, he led the strategic direction of the Administration’s $65 billion broadband connectivity portfolio and the White House’s Infrastructure Task Force.

In 2021, Will was also an advisor to the United States Secretary of the Treasury, Janet Yellen. In this capacity, he was a “Day 1” member of the Treasury team (<10 individuals) that developed emergency Department actions in response to the COVID-19 economic crisis. He was an architect of the Administration’s strategy for deploying over $80B of federal relief and recovery investment across community banking institutions, broadband, housing, and mobility programs. He also focused on capital access for American small businesses and tech start-ups, working to marry public sector, philanthropic, and private sector capital to achieve catalytic outcomes.

Between 2018-2020, before joining the Biden Administration, Will worked at Sidewalk Labs, a company backed by Alphabet (the parent company of Google), where he was the team lead focused on urban development, diligence, and strategic acquisitions to enable the commercial scaling of Sidewalk Labs, an Alphabet company seeking to combine forward-thinking urban design and cutting-edge technology to radically improve urban life. He was a part of the ambitious team that attempted to build the first smart city in North America.

From 2013 to 2016, Will assumed various roles in economic policy at the Treasury Department during the Obama Administration, providing critical expertise, recommendations, and support for Department priorities and initiatives. He was a recipient of the United States Secretary of the Treasury’s Meritorious Service Award in recognition of significant accomplishments and distinguished service during his Treasury career.

In 2010 until 2013, William began his career as a staffer on the United States Senate Banking Committee under Chairman Christopher Dodd, where he was a part of the committee that drafted, passed, and implemented the Dodd-Frank Act rule, which reformed and still regulates banks in the United States.  William also focused on derivatives regulations and Volcker Rules implementation.

Will holds a bachelor’s degree from Morehouse College and an M.B.A. from The Wharton School.
