Short Biography

Prof. Nelson earned a B.S. in Chemistry from University of California at Berkeley in 2004 and a  Ph.D. from the California Institute of Technology in 2012. After postdoctoral training at University of California at Berkeley, Prof. Nelson joined the UCLA faculty in 2015.
 

Research Interests

Broadly speaking, Prof. Nelson’s research program is focused on the development of enabling technologies for chemical synthesis and biology. His group will achieve this goal through two primary avenues of research.

Target-Driven Organic Synthesis:


 As both an inspiration for the development of new organic methodology and as a means to proactively contribute to the development of medicines, the Nelson Group will pursue the synthesis of bioactive complex molecules. Targets will be selected based on their biological activity and syntheses will be designed with a focus on modularity and efficiency.  Ultimately, through synthetic activities and collaborations, we hope to develop small molecules that will be widely utilized by practitioners of medicine and biology.
 

Reaction Development:


As a means to expand the methodology available to synthetic chemists, efforts to discover new concepts in catalysis and novel chemical transformations will be undertaken.   We are specifically interested in developing supramolecular organometallic catalysts that enable challenging stereoselective transformations.  Furthermore, the development of methodologies that rely on the catalysis of earth-abundant main group elements and base metals will be pursued.
