A full list of publications is hier.  A short list of one book and a sample of three papers looks like follows.

• Calculated Surprises. A Philosophy of Computer Simulation. New York: Oxford University Press, 2019.
  The book characterizes simulation modeling as a new type of mathematical modeling. It employs historical case studies and argues that experimentation, visualization, plasticity, and opacity are important concepts for reasoning about what makes simulation different.
• Lenhard, J. and H. Hasse (2023). "Traveling with TARDIS. Parameterization and transferability in molecular modeling and simulation." Synthese 201(129). doi.org/10.1007/s11229-023-04116-3.
  This paper exemplifies joint work in philosophy and engineering.
• Lenhard, J. (2022). "A Transformation of Bayesian Statistics: Computation, Prediction, and Rationality", Studies in History and Philosophy of Science, 92, pp. 144-151.
  Makes a claim about how using computational tools affects the concept of rationality underlying the (Bayesian) philosophy of statistics.
• Lenhard, J. (2018). "Holism or the Erosion of Modularity. A Methodological Challenge for Validation", Philosophy of Science, 85, pp. 832-844.
  Argues along two examples that the very methodology of computational modeling tends to undercut validation efforts.
