Researcher Ravaged by Disease He Studies

Rahul Desikan sits at his dining room table, a large computer screen before him, and works on his latest scientific paper. He types a single letter, then another, then another. For a man in a hurry, desperately trying to rid the world of terrible diseases, it’s an excruciatingly slow process.

Using a special mouse strapped to his forehead that detects his smallest movement, Desikan moves a cursor around an on-screen keyboard. When he finds the letter he wants, he clicks a button with his right thumb, and it appears in a white space to the side. Repeating the process over and over, he debates research ideas with colleagues, analyzes reams of data and competes for grants. He types so much that he occasionally wears out the clicker.
