Nicholas Crossland

Assistant Professor, Pathology

Dr. Crossland is a board certified Veterinary Anatomic Pathologist. He shares a dual appointment as an Assistant Professor in the Department of Pathology and Laboratory Medicine at Boston University School of Medicine and an Investigator at the NEIDL. He leads and orchestrates a comparative pathology laboratory service that operates safely and efficiently in all levels of biocontainment. His specialization is in veterinary pathology and the use of animal models to best mimic human diseases as a means to understand pathogenic mechanisms of emerging infectious diseases and as a platform to evaluate efficacy of medical countermeasures.
In addition to qualitative histomorphological reporting, he has extensive experience in biomarker assay development and interpretation of chromogenic and fluorescent immunohistochemistry and in situ hybridization assays. He also utilizes digital pathology and image analysis algorithms to refine legacy workflows with quantitative datasets.
His lab space is also open to MS graduate students from BUSM, where he provides mentorship in standard histology techniques, the development and optimization of immunohistochemistry and in situ hybridization, and image analysis to answer complex biological questions being asked by NEIDL investigators.
