Assistant Professor, Department of Dermatology


Dr. Ericson joined the department in 1996 as part of the Clinical Research Division team. She is currently director of the Dermatology Imaging Center located in 2-145 Jackson Hall. Her interests lie in adapting imaging techniques such as single- and multi-photon laser scanning microscopy, second harmonic generation, correlative microscopy, TEM and SEM, live imaging, and super resolution microscopy to help parse out mechanisms of disease with cutaneous manifestations.

"I have a broad background (15+ years) in examining, imaging and quantifying biomarkers in skin and other organs using laser scanning microscopy and 3-dimensional analysis. I have successfully administered fruitful collaborative projects (including staffing, research protections, budgets, experimental plans) and produced several peer-reviewed publications from each project as well as funding. Based on my success with previous projects, I am aware of the importance of constructing a realistic research plan, timeline, and budget. Collaboration and innovation have been hallmarks of my research endeavors and afforded me the benefit of making contributions to a) understanding and treating cancer pain, b) identifying molecular targets of phytochemicals, comprehending the role of the peripheral nervous system in skin and hair biology, and c) recognizing the implications of Bartonellosis. I see a clear path towards recognizing, testing, and understanding this pathogen that is causing unprecedented health issues world-wide due to its stealth nature."

Research Summary/Interests

Of particular interest is the role of biofilms in chronic Bartonellosis and subsequent pathologies working with colleagues at the U of MN Twin Cities and Duluth campuses, North Carolina State University and UNICAMP in Brazil. Successful research collaborations include work with hair biology, the tick/mammal interface in Anaplasma spp., sun-screen development, natural products and skin cancer, leukemia, breast cancer, sickle cell disease and tumor pain.

Research collaborations:  University of Minnesota Departments: Hormel Institute, Hematology, Oncology and Transplant Medicine, Entomology, Veterinary Medicine, Chemistry, Duluth Medical School, and MinnCResT

Research affiliations outside of UMN: Vector Borne Disease Lab at North Carolina State University, Translational Medicine Group in North Bethesda, MD and Sao Paulo and UNICAMP in Brazil, Chemistry Dept at UMass
