…according to https://research.com./. The d-index is the H-index for discipline specific journals. Unfortunately, they don’t specify the list of discipline-specific journals, but it almost certainly does not include student-edited law reviews (but almost certainly does include all faculty-edited law-related journals, including interdisciplinary ones). Some fields are promiscuous with their citation practices (e.g., health law and bioethics, law & psychology), and some are well-represented with faculty-edited journals (e.g., international law and cognate areas), so this is kind of an apples to oranges comparison, which is why I list the scholar’s primary areas of scholarship. For ties, the order reflects the total number of citations, as well as the D-index, with faculty coming first having more citations. Only non-emeritus law faculty are listed.
