Hello, fellow electron microscopy aficionados! My name is Dr. Nicholas Rudawski, (please call me Nick) and I am a faculty-level staff member of the Nanoscale Research Facility of the Herbert Wertheim College of Engineering at the University of Florida. On my channel, I cover all things electron microscopy-related from scanning/transmission electron microscopy, to dual focused ion beam/scanning electron microscopy and everything in between. If you want to take your microscopy skills to the next level and are looking for someone to assist you on your microscopy journey, you definitely came to the right place!
