A professor of chemistry, nanoscience and chemical complexity, Lee Cronin and his research group investigate how chemistry can revolutionize modern technology and even create life.

Why you should listen

Lee Cronin's lab at the University of Glasgow does cutting-edge research into how complex chemical systems, created from non-biological building blocks, can have real-world applications with wide impact. At TEDGlobal 2012, Cronin shared some of the lab's latest work: creating a 3D printer for molecules. This device -- which has been prototyped -- can download plans for molecules and print them, in the same way that a 3D printer creates objects. In the future, Cronin says this technology could potentially be used to print medicine -- cheaply and wherever it is needed. As Cronin says: "What Apple did for music, I'd like to do for the discovery and distribution of prescription drugs."

At TEDGlobal 2011, Cronin shared his lab's bold plan to create life. At the moment, bacteria is the minimum unit of life -- the smallest chemical unit that can undergo evolution. But in Cronin's emerging field, he's thinking about forms of life that won't be biological. To explore this, and to try to understand how life itself originated from chemicals, Cronin and others are attempting to create truly artificial life from completely non-biological chemistries that mimic the behavior of natural cells. They call these chemical cells, or Chells. 

Cronin's research interests also encompass self-assembly and self-growing structures -- the better to assemble life at nanoscale. At the University of Glasgow, this work on crystal structures is producing a raft of papers from his research group. He says: "Basically one of my longstanding research goals is to understand how life emerged on planet Earth and re-create the process."

What others say

“Professor Lee Cronin is a likably impatient presence, a one-man catalyst. Cronin, 39, is the leader of a world-class team of 45 researchers at Glasgow University, primarily making complex molecules. ” — The Guardian

7 talks on the wonder of 3D printing

February 7, 2013

From ordering movie tickets to booking a dentist appointment, mobile and web apps have made the tasks of daily life easier. But there are some things that an app can’t do. Standing in line at the pharmacy is one of them. In today’s talk, Lee Cronin asks: “Could we make a really cool universal chemistry […]

A 3D printer for molecules: Lee Cronin at TEDGlobal 2012

June 26, 2012

Lee Cronin is a chemist at the University of Glasgow. At TEDGlobal last year he took the stage to describe his audacious idea to create inorganic life. This year, he is presenting a short talk on another ambitious idea: a 3D printer that, instead of printing objects, prints molecules. The question he starts with is, “Could we make a […]

Quotes from Lee Cronin

As a chemist, I wanted to ask myself the question frustrated by biology: What is the minimal unit of matter that can undergo Darwinian evolution?

Up until maybe a decade ago, we were told that life was impossible and that we were the most incredible miracle in the universe.
