With my colleague, Dr. John Knox, I have worked on the origins and biogeography of Helenium virginicum, an endangered plant found in certain sinkhole ponds in Augusta and Rockingham Counties, Virginia. By comparing the DNA sequences of the Internal Transcribed Spacer (ITS) regions, we have determined the relationship of H. virginicum to the other members of the Helenium autumnale species complex and its identity with disjunct populations recently found in southeastern Missouri. Our data also identified a sister-group of H. virginicum, uniquely found on the Bruce Peninsula, Ontario, Canada.
I also work with the W&L Legal Clinic's faculty and students who represent, pro bono, coal workers and their families to obtain compensation for medical treatment and disability in suits against coal companies. Since many of the facts in these cases revolve around the immunological bases of black lung disease (Coal Workers' Pneumoconiosis) undergraduate students and I research the current literature on this disease and report our findings to the Legal Clinic's faculty and students. We provide lawyers with the biological information and explanations needed for their court hearings.
