Tina Del Carpio
Tina Del Carpio (pronouns: they/them) began their PhD in the fall of 2017 in Ecology and Evolutionary Biology. They joined the Lohmueller lab in 2019. Tina’s research reflects their interests in both genetics and improving graduate education. They are estimating recombination rates in North American gray wolf populations and breed dogs to investigate how domestication has influenced the evolution of recombination rates. They are inferring recombination rates using both population linkage disequilibrium (LD) based methods and pedigree based methods. Tina is also studying the impact of UCLA’s Competitive Edge bridge program for new doctoral students from underrepresented minority (URM) backgrounds. They hope to learn the strengths and areas of growth of the Competitive Edge program to improve URM student experiences and retention at UCLA. After completing their PhD, Tina plans to pursue a career working with STEM graduate programs to improve equity, diversity, and inclusion.
