Computational Spatial Transcriptomics Jobs in Nashville, TN

The Spraggins group develops integrated molecular imaging technologies to elucidate the molecular basis of health and disease. Modern instrumentation and computing capabilities have enabled researchers to move beyond reductionist biology and, instead, probe how the components of biological entities (e.g., molecules, cells, and tissues) interact globally to reveal the underlying biology of disease. This systems biology approach has been accelerated by advancements in high-throughput 'omics' technologies, however, genetic and molecular information are only part of the story. The challenge lies in understanding how these parts interact and how perturbations to the system relate to disease. To address this challenge, we are advancing instrumental capabilities and developing the computational tools necessary to integrate and mine multimodal data sets that bring together imaging mass spectrometry, highly multiplexed immunofluorescence microscopy, and spatial transcriptomics.
The Spraggins laboratory is part of the Mass Spectrometry Research Center (MSRC) and Department of Cell & Developmental Biology at Vanderbilt University. The MSRC consists of two research groups, including the Spraggins and Schey groups, and three cores that offer analytical services in proteomics, small molecules, and tissue imaging using mass spectrometry. The MSRC conducts collaborative research programs with investigators in nearly every Center and department in the Medical Center and Vanderbilt University as well as many trans-institutional initiatives. Team members have access to state-of-the-art instrumentation including 6 imaging mass spectrometers, a CODEX highly multiplexed immunofluorescence platform, 2 fluorescence slide scanners, a laser capture microdissection system, a Xenium in situ platform, and a GeoMx spatial transcriptomics instrument, as well as a collection of commercial and custom software for the analysis of imaging, multi-omics, and microscopy data. The group's research is embedded in large national consortia, including the Human BioMolecular Atlas Program (HuBMAP), the Kidney Precision Medicine Project (KPMP), and the Human Tumor Atlas Network (HTAN).
