Joshua Peñalba received his Bachelor's Degree (with honors) from the University of California, Berkeley in 2013. During that time, he developed his skills and passion for evolutionary biology in the Museum of Vertebrate Zoology. His undergraduate research focused primarily on phylogenetics and phylogeography of African and North American avifauna with Dr. Rauri Bowie and Dr. Carla Cicero. Additionally, he was involved in various natural museum work and field expeditions during this period. Currently, he is undertaking a PhD with Dr. Craig Moritz and Dr. Leo Joseph through the joint ANU-CSIRO Centre for Biodiversity Analysis.

Broadly, my research focuses on multiple aspects of speciation genomics. Speciation genomics focuses on the landscape of genomic divergence through the speciation process. This "landscape" can be influenced by multiple factors including the "drivers" of speciation, the biogeography of the organism, and other stochastic processes. My research aims to use empirical data to test standing hypotheses in speciation theory using modern genomic techniques in an Australian bird suture zone. The focal suture zone is located in northern Queensland, where populations from the Cape York Peninsula and central Queensland are shown to be in secondary contact and some of which hybridise. I will be utulising multiple species from Meliphagoidea (honeyeaters, fairywrens, pardalotes, gerygones, etc.) to take a comparative approach to test these hypotheses.
