book cover

Jeff, Alex, and Alon's paper on the development of cyclopropenimine catalysts has been accepted to Chemical Science.

Our paper in collaboration with the Campos group on the invention of cyclopropenium-based polyelectrolytes has been accepted to Nature Communications.

The Lambert group welcomes first year graduate students Barry Cohen and Zack Strater, as well as undergraduate researchers Louisa Carpenter-Winch and Gabrielle Lovett.

The Lambert group welcomes postdoctoral researcher Alexandre Barthelme from the University of Nottingham.

Jeff has defended his thesis and is off to a postdoctoral stay with the Buchwald group at MIT. Good luck Jeff!

Jeff's paper in collaboration with the Vetticatt group regarding transition state analysis of chiral cyclopropenimine catalysis has been accepted to J. Am. Chem. Soc. Congratulations Jeff!

Tristan has been selected as a Swiss Chemical Society Lecturer for 2015.
