I am a physician on the emeritus faculty of the University of Vermont in Burlington. I have practiced General Internal Medicine, and taught both research methods and clinical Internal Medicine. I am still engaged in research on quality of care.
I'm a good copy-editor in general, and I have lots of special knowledge in medicine, medical research, epidemiology, and statistics.

For images, there are free tools like GIMP and ImageMagick, and commercial ones like Adobe Photoshop that provide a variety of processing filters. The preferred formats are Scalable Vector Graphics (SVG) for drawings, and Portable Network Graphics (PNG) for pictures. You may also use JPEG.
Vector graphics are preferred to raster graphics for drawings, because they can be scaled as needed without losing information, and because they can be more easily edited. Please remember to follow our guidelines and policies when uploading images.
