Angela Kruse, PhD (Presenter)

Presenter Bio: Angela Kruse is a research faculty member in the department of Cell and Developmental Biology and the Mass Spectrometry Research Center at Vanderbilt University. Her research integrates imaging mass spectrometry, proteomics, spatial transcriptomics, biochemistry, and microscopy to understand how diabetes affects the molecular environment in the pancreas, kidney, and eye. She received her Ph.D. in Plant Pathology with a focus in Biochemistry from Cornell University prior to conducting her postdoctoral studies under the guidance of Drs. Richard Caprioli and Jeff Spraggins at Vanderbilt University. She plans to spend her career applying and integrating cutting edge technologies to address important challenges in human health and the environment.


The function of healthy human organs is dependent on highly coordinated interactions between cells and structures in 3-dimensional space. As part of the Human Biomolecular Atlas Program (HuBMAP), we apply multimodal molecular imaging to characterize the cellular and molecular organization of the human kidney, pancreas, and eye. Our pipeline integrates imaging mass spectrometry, highly multiplexed immunofluorescence microscopy, autofluorescence microscopy, stained microscopy, spatial transcriptomics, and spatial proteomics to understand molecular variation in healthy compared to diabetic individuals. Each modality is specifically chosen to span a wide range of spatial scales (e.g., single cells, functional tissue units, neighborhoods, and whole organs) and molecular classes (e.g., metabolites, lipids, proteins, and RNA transcripts). Using this workflow, we have identified key pathways involved in diabetic pathologies including pancreatic islet dysfunction and kidney glomerular sclerosis.
