Ashley L. Kiemen, Ph.D. is an assistant professor in the computational division of the Johns Hopkins Department of Pathology. Kiemen’s main research interest is understanding microanatomical invasion patterns of pancreatic cancer by using a unique 3D reconstruction technology of serial histological sections. She integrates deep learning tissue labelling techniques with MRI images, DNA sequencing, immunohistochemistry, spatial transcriptomics, and immunofluorescence to characterize pancreatic cancer tissues. She also helped to map the microanatomy of a diabetic pancreas, skin, heart, fallopian tubes, liver, and lungs.

Kiemen earned her B.S. in chemical engineering from the University of Michigan in 2016, her M.S. in philosophy from the London School of Economics and Political Science in 2017, and her Ph.D. in chemical & biomolecular engineering from Johns Hopkins University in 2021.
