Darin teaches political science at Missouri State University, where his areas of expertise include American government, American federalism (the constitutional relationship between the national and State governments), and State sovereignty.

He has worked at Missouri State in the Center for Social Sciences and Public Policy Research, and as Senior Analyst for the Missouri Local Government Program. Darin has lectured extensively on Public Budgeting and Finance and has taught Public Administration there at the university in Springfield.

Since one of his primary areas of study is regarding State sovereignty, it is no surprise that Darin has been active in the Tea Party movement from the very beginning. He has spoken at multiple tea parties and has been at the forefront of the struggle to maintain our rights, freedoms, and liberties.
