I am a professor of political science in the Department of Political Science and the Reviews and Book Editor for the Congress & the Presidency journal. My main area of expertise is the American presidency in which my research has focused on the unilateral presidency and the administrative presidency. Specifically, I assess how presidents make public policy by circumventing Congress through a variety of unilateral powers and tools and how they use administrative tools to influence and control the federal bureaucracy in relation to the policymaking process. I have written extensively on one type of unilateral tool, presidential executive orders, and I am considered to be one of the leading experts on this presidential power. In addition, I have written pieces on presidential appointments, the president's cabinet, religion and the American presidency, and the Trump presidency.
