E.M.P.O.W.E.R. (Electron Microscopy Program for Organellar Workflow Education and Research)

About This Grant

Electron microscopy (EM) remains the cornerstone of structural biology, providing unparalleled resolution for visualizing the ultrastructure of cells, tissues, and organelles. Despite its critical importance, formal EM training programs have declined nationwide, leading to a shortage of skilled practitioners capable of mastering advanced sample preparation, imaging, and three-dimensional (3D) reconstruction. The E.M.P.O.W.E.R. (Electron Microscopy and Professional Opportunities for Workforce Enhancement and Research) R25 program directly addresses this gap by training the next generation of biomedical researchers to apply, innovate, and sustain cutting-edge EM technologies in scientific discovery. Each year, twenty selected trainees will participate in an immersive training experience at Vanderbilt University, engaging in hands-on instruction across the full EM continuum Transmission Electron Microscopy (TEM), Correlative Light and Electron Microscopy (CLEM), and 3D Electron Microscopy (3DEM) using Focused Ion Beam-SEM (FIB-SEM) and Serial Block Face-SEM (SBF-SEM). Participants will gain practical expertise in fixation chemistry, resin embedding, ultramicrotomy, sectioning, image acquisition, and 3D data reconstruction using advanced computational platforms. The curriculum emphasizes the integration of classical EM craftsmanship with modern correlative and computational imaging techniques. Trainees will also receive structured instruction in complementary advanced light microscopy approaches, including confocal laser scanning microscopy, Airyscan, structured illumination microscopy (SIM), total internal reflection fluorescence (TIRF), and light sheet microscopy, enabling them to bridge molecular and ultrastructural scales of analysis. Aim 1: To develop and implement a comprehensive EM training curriculum that unites foundational and modern techniques for the study of subcellular architecture, ensuring mastery of both instrumentation and quantitative image analysis. Aim 2: To establish a mentor-guided practicum series where trainees apply EM approaches to active research projects investigating organelle ultrastructure, mitochondria ER interfaces, and other nanoscale interactions central to cellular function and disease mechanisms. Aim 3: To build technical leadership in microscopy through professional training that prepares participants to manage imaging laboratories, optimize workflows, and train future EM users. Through this integrated structure, E.M.P.O.W.E.R. will produce a technically proficient, scientifically rigorous, and sustainable EM workforce. Graduate students, postdoctoral fellows, and junior faculty will emerge equipped to independently conduct high-resolution imaging, perform quantitative 3D data analysis, and lead collaborative imaging initiatives that advance mechanistic discovery in cell and molecular biology. By restoring the craft of electron microscopy while embracing modern innovation, this program ensures that EM remains a living, evolving discipline, one that continues to define the frontier of biomedical research and technological excellence.
