Leopold Leadership Fellow

Doctoral students

I’m a fourth year PhD candidate studying the movement and impact of mercury in terrestrial ecosystems of California. 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 fourth 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 third 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 second year PhD student on the Ecology and Evolution tract in the Hadly Lab. My research goals focus on improving the effects of rewilding and rewiring on ecosystem functions and ultimately landscape-scale delivery of ecosystem services through applied conservation genomic techniques and network theory. 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 second 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

I am a second year PhD student in the Hadly Lab. I am broadly interested in environmental microbiology and the effects of climate change on microbial diversity and ecology. Currently, I am investigating the distribution and diversity of E. coli in the wild animals at Jasper Ridge. During my undergraduate career, I studied microbiology and environmental science. I also did research in a plant pathology lab on the type-III effector proteins of Pseudomonas syringae, a pathogen of tomato and Arabidopsis, and the role of calmodulin in Arabidopsis immunity against P. syringae.

Kate Lagerstrom

Postdoctoral Scholars

I am a postdoctoral fellow in the lab, primarily interested in using genetic data to help conserve species and habitats in the context of environmental change. As part of my postdoc, funded by the Swiss National Science Foundation and Jasper Ridge Biological Preserve, I seek to assess the reliability of environmental DNA-based species detection for faunal diversity surveys. To do this, I compare species for which their DNA was found in soil samples near camera traps with the species recorded by these cameras. If successful, our project would demonstrate the ability of environmental DNA to supplement or replace existing approaches and to facilitate wildlife monitoring. My other research project consists in documenting a trophic cascade using long-term camera trap data and to demonstrate the critical role that apex predators play in ecosystems. Prior to this postdoc, I had completed my PhD at the Swiss Federal Institute of Technology in Lausanne, where my research focused on the adaptation of various species to local environmental conditions using populations and landscapes genetics/genomics.

Kevin Leempoel

I am currently a Postdoctoral Scholar at the Stanford Woods Institute for the Environment. 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 and climate change. I completed my dissertation in the Hadly Lab in June 2017. This work aimed at investigating the mechanisms underlying species tolerance of extreme environments, focusing on pika (genus Ochotona).

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 sophomore planning to major in Biology with a minor in Economics. I am currently working with Maria Viteri on projects involving small mammal populations and how they have been affected by urbanization, climate change, and other factors. I am especially interested in environmental policy and how it can affect wild flora and fauna but also human populations.

Carson Conley

I am a senior majoring in Biology. I’m interested in genetics, animal behavior, and how they relate to population dynamics. I will be working with Kevin to identify individual mountain lions in Jasper Ridge based on their footprints. We will also be analyzing eDNA in water taken from around the preserve.

Kathryn Hoaglund

I am a junior majoring in Biology and minoring in Computer Science. I am currently working with Katie Solari and Kate Lagerstrom to study the distribution of pathogens, specifically Giardia, around the Stanford Dish and Jasper Ridge Biological Preserve.
