Doctoral students

I’m a third year PhD candidate interested in environmental toxicants, adaptations, epigenetics/epigenomics and evolutionary genomics. My research is aimed at understanding the impact of environmental toxicants on mammal fauna through the lens of genomics/epigenomics. Currently, I am focused on the effects that mercury released from small scale gold mining have on bat fauna and the terrestrial ecosystem structure and function as a whole. Prior to joining the Hadly lab at Stanford, I was working on my master’s degree with Dr. Liliana Cortés-Ortiz at the University of Michigan. For my thesis, I studied the diversity and evolutionary history of Peruvian red howler monkeys.

Sergio Redondo

I am a third year PhD student in the Microbiology and Immunology Department, and am being co-advised in the Kirkegaard Lab. My interests involve understanding how ecological characteristics contribute to host immune responses. In particular, many recently emerged viral diseases including Nipah, Marburg, SARS, and Ebola are hypothesized to have their origins in bats. My thesis research focuses on using bat ecology to investigate unique innate immune mechanisms employed to limit viral infection, and allow them to be a reservoir of highly pathogenic viral diseases in humans. Outside of lab, I am extremely passionate about outreach and empowering others through education.

Dorothy Tovar

I am a second year PhD student in the Hadly and Petrov labs interested in studying the patterns of speciation and diversity at the genomic level. Specifically, I am interested in using genomic methods to understand how species adapt and diverge because of ecological pressures. Previously, I have worked on genome evolution in Hawaiian picture-wing Drosophila, population genetics in Ariamnes spiders, and worked on several genome assembly projects.

Ellie Armstrong

I am a first year PhD student in the Hadly Lab and my research goals will focus on reducing the long- and short-term impacts on biodiversity by incorporating applied conservation genomics into management strategies and policy change. This research will explore efficient, effective and sustainable approaches to secure, monitor and identify future protected areas in Africa such that wildlife populations, ecosystem function and natural resources will be able to evolve while responding to environmental and anthropomorphic change and stressors. Previously, I was working as a behavioral endocrinologist focusing on the reproductive success and management of African elephant and black rhino and founded Wildtrax Explorations as a way to train the next generation of conservationists.

Jordana Meyer

I’m a first year PhD student in the Hadly lab interested in the intersection of conservation biology and paleontology, or conservation paleobiology. I specifically use recent accumulations of bones and young fossils to understand how faunal communities respond to environmental perturbations (such as climate change) as well as establish baselines for conservation. I’m coming from the Sereno lab at the University of Chicago where I identified crocodile remains from a Saharan archaeological site as the cryptic species, Crocodylus suchus.

Maria Viteri

Rotation students

I am a first year PhD student in the Goldbogen lab at Stanford's Hopkins Marine Station. I am interested in studying the biomechanics of rorqual swimming and feeding, with particular focus on the tail and ventral throat pouch. I am also interested in quantifying the hydrodynamic profile experienced by different areas of the rorqual body during swimming. I am coming from the Fish lab at West Chester University where I described the internal morphology of the tail flukes of seven odontocete species.

Will Gough

I am a first year PhD student in the Palumbi lab at Stanford's Hopkins Marine Station. I am interested in conservation genomics and genetics applications in coral reefs. Particularly, I seek to better understand reef-building coral resilience as climate change effects continue to impact these ecosystems. Previously, I have worked on Caribbean larval coral transcriptomics and Indo-Pacific coral population genetics.

Nia Walker

I am a first year PhD student in the Palumbi lab at Stanford's Hopkins Marine Station. I am interested in utilizing conservation genetics as a tool to study how corals react and adapt to disease, climate change, and other anthropogenic factors. Specifically, I aim to identify corals resilient to bleaching caused by thermal stress and then determine genetic differences between resistant versus susceptible corals, their symbionts, and their microbiome. Previously, I have worked on the conservation genetics of bluefin tunas and the population genetics of Kemp's ridley sea turtles.

Katrina Hounchell

Master's students

I am a senior honors student studying Earth Systems (BS) and Environmental Communication (MA) with an emphasis on education. I study the endangered Hispaniolan solenodon, using camera trapping, ecological transects, and species distribution modeling to inform conservation efforts. In the future, I hope to explore implications of climate change on human and animal populations.

Lauren Gibson

Postdoctoral Scholars

I’m interested in using genetic data to inform species and habitat conservation in the context of environmental changes. During my Postdoc, funded by the Swiss National Fund, I aim to assess the reliability of eDNA-based species detection for faunal diversity surveys. My past and continuing work has been to assess the adaptations of various species to local environmental conditions.

Kevin Leempoel

I recently completed by dissertation research in the Hadly Lab. This work aimed at investigating the mechanisms underlying species tolerance of extreme environments, focusing on pika (genus Ochotona). Pikas are small mammals related to rabbits. They are cold-specialists and only live at high elevations or high latitudes, with about half of the roughly 30 pika species living at elevations above 4000 m and many may be forced to even higher elevations due to climate change. Specifically, my dissertation research has focused on how pikas are capable of tolerating the extreme hypoxia of their high-elevation habitat. Through the utilization of museum tissue samples, extensive field work in the Indian Himalayas, and the only captive colony of pikas in the world, I have investigated hypoxia tolerance in pikas from three different angles: (1) molecular evolution in mitochondrial candidate genes; (2) variation in gene expression along an elevational gradient within a population; and (3) plasticity in gene expression within an individual in response to hypoxia. Now, as a postdoc in the Hadly lab I am working on a project in collaboration with the department of Earth System Sciences to investigate how the population genetics of muskrat in Alberta, Canada have been impacted by damn construction.


Katie Solari

Undergraduate Researchers

I am a rising sophomore planning to major in computer science with a concentration in biocomputation. I will be working with Sergio studying bat epigenetics. I am interested in investigating the techniques by which biological data is collected and analyzed in the field.

Xóchitl Longstaff

I am a junior studying Earth Systems and CSRE. I am working on a research project studying a group of extinct Caribbean eulipotyphlans, examining possible factors for extinction such as limited diet. I am particularly interested in the implications for current conservation efforts that could be revealed.

Sijo Smith

I am a Sophomore majoring in Biology with a potential concentration in Microbes and Immunity. I am interested in infectious disease, particularly zoonosis and the way these diseases move through ecosystems. This Summer, I will be studying the consequences of mining activity on California bats.

Stephanie Sila

I am a freshman who plans to major in Biology with a concentration in Ecology and Evolution. I am currently working with Ellie on a project that applies survivorship data and genomic and pedigree analyses to the conservation of African Lions and several tiger subspecies. One key aim of the project is to identify the extent to which these big cats are inbred, and how that affects the occurrence of deleterious mutations in their populations. In the future, I hope to use genetic techniques to understand how species respond to anthropogenic pressures.

Lucy Arnold

I am a freshman double majoring in anthropology and biology. I am working with Sergio on the Black Rhino Genome Project to inform rhino population conservation strategies and wildlife management policy. I am especially interested in how humans interact with wildlife and how that relationship defines what it means to be human.
