The Krishnamurthy Lab
Research in our group is focused on the use of synthetic organic chemistry and methodology to
- experimentally address questions concerning the origins of life with respect to the advent of functional monomers and the emergence of informational polymers.
- fashion artificial informational polymers in order to expand the interface between synthetic nucleic acids and the natural biopolymers (proteins and RNA/DNA).
- make available novel molecular tools that may provide new avenues for probing biological systems and for research in synthetic biology.
- make available diverse novel molecules and intermediates that would be useful in chemical therapeutics.

New Clues to Chemical Origins of Metabolism at Dawn of Life
(by John Rennie, Deputy Editor, Quanta Magazine)
On the early Earth, a forerunner of the complex cycle of reactions that underpins metabolism in today’s cells might have originated from interactions between just two simple, versatile molecules in water, according to new research.
