I have a background in molecular genetics and conservation biology. My major research focus is to develop non-invasive tools for monitoring and conservation of wildlife populations. During my tenure at the University of Washington, Seattle I led a project to develop non-invasive monitoring methods to study ecological impacts of apex predator recovery. I developed a Real Time PCR and High Resolution Melt curve based method for species identification of large carnivores from scat.
As part of the project at UW, we used detection dogs for sampling of scat from seven large carnivores in high wolf density areas of Northeast Washington. This allowed high sample numbers which are necessary for comprehensive analyses in ecological studies. As part of this study we were able to determine distribution of large carnivores by season, species interactions and resource use as well as impact of wolf recovery on human-wildlife conflicts.
I recently received a grant from the Society for Conservation Biology-Marine Section for biodiversity indexing of sharks in India. I am currently involved in developing a species identification method for -sharks, rays and chimaeras using portable sequencers.
Secondly, I am interested in developing microbiomes as a non-invasive monitoring tool for wildlife populations. I am currently involved in studying microbiomes from killer whales and sharks to determine the effect of contaminants like persistent organic pollutants and heavy metals on the health of these marine species.
I enrolled the Joint Doctoral Program in Ecology at SDSU/UC Davis in the fall 2016. Before I joined the Dinsdale lab, I received my Bachelor in Biological Sciences (University of Brasilia, 2011) and defended a Master’s in Marine Ecology (Federal Fluminense University, 2015) in Brazil, where I was born and raised. The aim of my PhD dissertation is to investigate the relationships between the holobiont physiology and the associated microbiome. I am addressing this aim by conducting in situ and laboratory experiments in coral reefs and kelp forests.

I received my BS with an emphasis in molecular biology from San Diego State University in 2016. Following my graduation I moved to Seattle where I was hired as a level two laboratory technician at the Fred Hutchinson Cancer Research Center. In 2017 I returned to San Diego to enroll in the Joint Doctoral Program in Cellular and Molecular Biology at SDSU/UCSD. As a joint student of both Dr. Dinsdale and Dr. Forsberg, I intend to marry analytical techniques and next-generation sequencing to answer ecological questions concerning the well-being of sharks. The aim of my study is to develop measures of shark health, using both metabolomic analyses of the blood and metagenomic analysis of the skin microbes. By combining the two measures I will identify microbes that may be causing stress to the shark and be able to provide an early warning system of the declining health of the organism.
I enrolled in the Biological and Medical Informatics Masters program in the fall of 2017 and have been involved with the Dinsdale lab for the same amount of time. My undergraduate work was done at UC San Diego (go Revelle!) in Human Biology where I was a member of the Leutgeb lab studying the role of the hippocampus in memory formation and spatial mapping. From there I participated in studying the role of key proteins of CRLF2 Acute Lymphoblastic Leukemia at Loma Linda University with Dr. Kimberly Payne. Currently I am under the tutelage of Dr. Dinsdale investigating the microbial community structure and interactions in the mucosal layers of corals using metagenomics and other computational tools. From this analysis we hope to construct a mathematical model that can help us understand and predict these interactions so that ultimately we may comprehend the role microbes play in coral health.
I joined the Dinsdale Lab in 2018 after receiving my BS in Marine Biology from the University of Hawaii at Manoa. I am currently a Masters student in San Diego State University’s Ecology Program. I have a background in coral research, scientific diving, and fish research. My current research focuses on Leopard Shark skin microbial ecology. I am also currently working on a NSF GRFP proposal.
Hi! My name is Isabella Livingston and I am a third year Biology student with an emphasis in Zoology. I am extremely passionate about animals, especially Sharks, and I hope to pursue a career studying those beautiful creatures! Since joining the lab in Spring of this year, I have helped on a few different projects but mainly the study on Sharks that Shaili Johri has been conducting and putting together! This summer I spent some time in Sydney studying the marine and microbial ecology in the water in the harbor! Below are some pictures from my visit as well as a poster that was presented this summer in India of our findings in the Shark project!
I am an undergraduate majoring in Biology with an emphasis in Marine Biology at San Diego State University. Before attending San Diego State University, I first got involved in marine science by working at the Seymour Marine Discovery Center at Long Marine Lab at UC Santa Cruz. There I loved working with their swell sharks and plan on pursuing shark research in graduate school. Currently I am helping out with two projects in the lab, one looking at the role of microbes on sharks and the other linking genotypes to phenotypes for marine bacterial strains through experimental analysis.
During my second year at San Diego State University, where I am currently an undergraduate student studying biology, I became a member of the Dinsdale lab. At a young age I spent a lot of time snorkeling and swimming in the ocean, which is where my interest in marine life and ecosystems was first sparked. Eager to discover more of what was beneath the ocean’s surface, I became a certified scuba diver at the age of ten. Ever since, my curiosity towards the oceans ecosystems and inhabitants has only continued to grow. When I first came to SDSU, becoming a member of a research lab was something I strived to do and the Dinsdale lab proved to be a perfect fit. As a member of the Dinsdale lab, I have had the opportunity to integrate my passion for scuba diving and marine life into my education. Now, I am currently completing my third year at SDSU and have worked on projects that study the linkage between genotypes and phenotypes of bacterial strains in different substrates as well as study the microbial community that lives on the skin of various species of sharks!
My name is Anissa Busch. I am currently pursuing a B.S. in Environmental Sciences. After transferring to SDSU, I was eager and excited to have the opportunity to join a lab to further my interest in research. I have been involved with the Dinsdale lab since January 2018. After joining, my love of conservation for marine predators (such as sharks) has grown immensely.
I have worked on a couple of projects. In the summer of 2018, I worked with Dr. Johri on Chondrichthyan conservation. The project involved identifying species of the class, Chondrichthyes, taxonomically and mapping their range. I am now currently working on my own project with fellow undergraduates in the lab, Isabella and Emma. We are using environmental DNA (eDNA) to detect the presence of sharks and other organisms in their community. We are able to do this by collecting seawater samples, extracting and sequencing the DNA from the water, and analyzing the DNA to determine taxonomic identities. With this data, we want to use this information for a better understanding of sharks’ population size and their distribution.
In the future, I plan on furthering my education by obtaining a Master’s degree. I will be graduating in the summer of 2019. Being a part of the Dinsdale lab has given me many opportunities in research and I look forward to applying these skills in pursuing my academic career.
