D.E. Shaw Research — Science Beyond Finance

David Shaw didn't limit himself to finance. He founded D.E. Shaw Research (DESRES), a research firm specializing in computational molecular biology:

• Anton — built a specialized supercomputer for molecular dynamics simulation, considered one of the fastest in the world in this field
• Drug discovery — molecular simulations help design new drugs
• Scientific publications — DESRES regularly publishes in top scientific journals like Nature and Science
• Scientific philanthropy — Shaw funds research on a scale comparable to major universities

This is a rare example of a Wall Street billionaire making genuine scientific contributions outside the world of finance.
