Dr. Wells - Medical Author

Dr. David A. Wells is a highly regarded author and educator, with a body of work that includes a 600-page authoritative reference book on bioanalytical drug sample preparation, over 20 publications in scientific journals, 6 book chapters, 12 invited presentations, 29 poster presentations, dozens of technical application notes, instructions for use, and numerous product brochures for sales and marketing of sample preparation products used in pharmaceutical bioanalytical laboratories.

In addition, over the last 15 years, Dr. Wells has written thousands of medical response letters intended for health care professionals. Written responses for physician inquiries about medical devices were entirely based on summarizing the published literature, and these letters commonly numbered 12 to 20 pages in length and required several days to create.
