Jonathan Collins is originally from Parkersburg, West Virginia and found his passion for chemistry as an undergraduate at Allegheny College. His career in organic chemistry began in the research laboratory of Professor Phillip Persichini where he studied carbon-carbon bond forming reactions mediated by boron.
After receiving his B.Sc. in 2005 he pursued his Ph.D. under the supervision of Tomas Hudlicky at Brock University in St. Catharines, Ontario. His thesis work included the total synthesis of various Amaryllidaceae alkaloids, opioids and cyclictols. Following completion of his Ph.D. in 2010 he took up a postdoctoral appointment at the Laboratory of Chemical Biotechnology at Technische Universit ät in Dortmund, Germany under the direction of Professor Dr. Andreas Schmid and PD Dr. Bruno Bühler. He investigated applications of biphasic whole-cell biotransformations and their downstream processing using supercritical carbon dioxide.
In 2012 Collins returned to the States as a visiting assistant professor and principal investigator at Amherst College. He joined the chemistry department at Whitman College in 2015 as an assistant professor. His research team, the Collins Lab, focuses on the development of new biocatalysts and supporting technologies for the efficient preparation of important small molecules.

The Collins Lab
The primary focus of the Collins Lab is on the development and application of biocatalysts for the selective oxyfunctionalization of small molecules. The Collins Lab employs a number of whole-cell-based systems for the production of chiral building blocks used in the chemoenzymatic synthesis of natural products and functionalized organic materials.
Biocatalysis
Over the last 30 years, the increasing scarcity of natural resources and the acknowledged impact of human industrial activity on our environment have led to a shift toward sustainable development. Within the chemical community this has translated into the search for “green” alternatives to traditional synthetic methods. The principles of green chemistry highlight the need for the development of processes which are highly selective, efficient and utilize environmentally-benign materials. Biocatalysis is uniquely positioned to meet these challenges as enzymatic reactions are often chemo-, regio- and stereo-selective while operating in water, under mild conditions.
Our approach to biocatalysis is heavily influenced by our point of view as synthetic organic chemists. We hope to focus our efforts in the development of new biocatalysts and supporting technologies toward efficient preparation of important small molecules. Accordingly, The Collins Lab is involved in three main areas of research: Engineering of powerful new biocatalysts to fill unmet synthetic needs, demonstration of their utility through their use to total synthesis, and the application of synthetic organic chemistry to develop supporting technologies capable of shortening development times and making biotransformations easier to use. Our ultimate goal is to encourage a shift toward a synthetic paradigm in which biocatalysis is adopted as a “first generation” method for efficient and environmentally responsible synthesis. Some examples of projects of current interest in the lab are:
- Investigation of molybdenum cofactor-containing dehydrogenases as productive biocatalysts for the stereoselective oxyfunctionalization of hydrocarbons.
- Development of chemoenzymatic methods for the synthesis of natural products, pharmaceuticals, and materials.
- Synthesis and application of custom organic materials/phases for enhanced biphasic biocatalytic system productivity and ease of downstream processing.
