CURRENT GROUP MEMBERS


Postdocs


Guillermo Caballero Garcia ๐Ÿ‡ฒ๐Ÿ‡ฝ


Guillermo (nickname Memo) was born and raised in central Mexico. He studied chemistry at the Autonomous University of the State of Mexico, graduating in 2014. He then taught chemistry at the high school level (at the same high school he attended) for one year before starting his Ph.D. at the University of Cambridge. During his Ph.D., in Jonathan Goodman's group, he worked on asymmetric organocatalysis using chiral phosphoric acids and did computational chemistry to explain enantioselectivity outcomes. Memo joined the Britton group in 2021 and he's currently working on the total synthesis of complex molecules. When he is not doing science you can find him at the Jackalopes reading sci-fi novels while enjoying a beer with nice metal music.


Graduate Students


Ulises Vargas Cruz ๐Ÿ‡ฒ๐Ÿ‡ฝ


Ulises was born and raised in Toluca, Mรฉxico. In 2024, he received his degree in chemistry from the Autonomous University of the State of Mexico. During his degree, he discovered his passion for organic chemistry and had the opportunity to work on nitrene cyclization for the synthesis of fused heterocycles under the supervision of Dr. Moises Romero. Ulises joined the Britton lab in September 2024 as a Ph.D. student researching photochemical C-H fluorination using decatungstate. Outside the lab, Ulises enjoys watching movies and hiking.


Peter Palermo ๐Ÿ‡จ๐Ÿ‡ฆ


Peter was born in Mississauga Ontario, where he completed his BSc in honours Biochemistry at the University of Waterloo and gained a keen interest in organic chemistry under Professor Graham Murphy. Through a USRA, he studied the synthesis of radiolabeled Hoesch dye for DNA/RNA aptamers and later completed his undergraduate thesis with Professor Michael J. Chong developing methodology for the synthesis of Pyrethrin natural product analogues. Peter started his PhD at SFU in September 2025, studying methodology for the total synthesis of eribulin. Outside of the lab he enjoys reading, hiking and all kinds of nerdy interests.

James Song ๐Ÿ‡จ๐Ÿ‡ณ


James was born and raised in Beijing, China. He completed his BSc (Honours) in Chemistry under the supervision of Dr. Mark Lautens, where he worked on Rh/Ni dual-metal catalysis. He joined the Britton group in August 2026 to pursue a PhD in the total synthesis of complex natural product. Outside the lab, he enjoys reading history and science fiction, playing the electric bass, and working out. He also, admittedly, spends a great deal of time in front of a screen, frustrated over video games. 


Cassandra Sgarbi ๐Ÿ‡จ๐Ÿ‡ฆ


Cassandra was raised in Richmond, B.C., and completed her B.Sc. Combined Honours in Chemical Biology at UBC. During her undergraduate studies, she worked under the guidance of Dr. David Perrin, where she focused on the synthesis of unnatural amino acids and the total synthesis of peptide natural products. Cassandra joined the Britton lab in 2026 as a Ph.D. student, where she is currently working on the synthesis of iminonucleoside analogues. Outside of the lab, Cassandra enjoys staying active, drinking tea, and exploring new and exciting hobbies.

Sam Rommel ๐Ÿ‡บ๐Ÿ‡ธ


Sam hails from colourful Colorado, where he attended the University of Denver, completing his B.Sc. in Chemistry with distinction. While at the University of Denver, Sam conducted research under the supervision of Dr. Brian Michel, where his work focused on using organometallic catalysts for ethylene detection. Sam joined the Britton Lab in the fall of 2026, where he is currently working on optimizing the cyclization of RAvIN ketones to produce nucleoside analogues. In his free time, Sam enjoys mountain biking, ski touring, hiking, and all things outdoors. He is excited to explore all that British Columbia has to offer!
