Luis was a 4th year undergraduate and aspiring graduate student majoring in Molecular and Cell Biology. He joined the Arkin Lab in the summer of 2019 under the mentorship of Dr. Carim, with whom he studied phage-tail like bacteriocins, also known as tailocins. His first project encompassed designing vectors for the construction of recombinant tailocin proteins in order to investigate genetic determinants of killing specificity. He helped conduct genome-wide fitness assays to elucidate genetic factors of bacterial resistance to tailocins in non-canonical organisms such as Pseudomonas fluorescens and Pseudomonas protegens. When not in the lab, you can catch him with a Nikon taking photos around the city, riding his bike along the marina, playing soccer at the park, or on a hiking trail. Outside of research, Luis is passionate about providing guidance, support, and information to aspiring and current students about the college application process and the college life, especially as it pertains to the experience of first-generation, low-income, undocumented/DACAmented, and LatinX students in higher education. To this end, he actively devotes his time to the Let’s Talk Universi-Tea Podcast – a project created alongside a group of his childhood friends and which is soon to be released.
