On behalf of our faculty and staff, welcome to the Chemical and Biomolecular Engineering Department at the UCLA Henry Samueli School of Engineering and Applied Science.<br><br>This is a wonderful time to be a chemical and biomolecular engineer, as our profession is prepared to solve the most pressing problems facing the world, namely in the areas of energy, the environment, and healthcare.<br><br>The field of chemical engineering traditionally lies at the nexus of physics, chemistry, and mathematics. Chemical Engineers created the first revolution of chemical technology in the early 20th century. As an example, the Habor-Bosch process, invented by the German chemical engineers in the 1900's for artificial nitrogen fixation, solved the food shortage problem in the early 20th century and enabled the growth of the world population from 1 to 7 billion. The process is still being used today to synthesize fertilizers for the production of food and
