I was born and raised in Sacramento California and have stayed in that area for most of my life. After high school, I decided to make the bold move by traveling abroad and attending UC Davis (which is 40 miles away from Sacramento). There I majored in Biochemistry, Molecular/Cellular biology and Psychology. One of the required courses I had to take for the major was organic chemistry. I enjoyed the course so much that I decided to pursue a graduate career in the field. Thus, I completed my PhD in chemistry under Professor Mark Mascal, synthesizing oxonium ions with unusual topologies which impart unprecedented chemical behavior.

After earning my PhD, I decided on a change of scenery and traveled to the University of Strasbourg in France where I worked with Nobel Laureate Jean-Marie Lehn, exploring the rapidly growing field of constitutional dynamic chemistry.

In November 2013, I returned to the United States, where I have been serving as a squire for Sir J. Fraser Stoddart, and expanding the realms of molecular topology and materials chemistry.
