Dr. Jason Sexton (Associate Professor; Principal Investigator)
Dr. Sexton applies an evolutionary perspective and a collaborative interdisciplinary approach to pressing questions in evolution and ecology. He uses field and greenhouse experiments, genetic analyses, environmental modeling, physiological analyses, and biogeographic datasets to address these questions. Although he focuses primarily on plant climate adaptation, he also actively contributes to research on sustainability science, from biological invasions, and maximizing species diversity under climate change, to the role of sociocultural adaptive capacity in biological conservation. His research is driven by urgent questions, and is grounded in empirical study to test, enhance, and expand ecological and evolutionary theory.
Dr. Molly Stephens (Assistant Project Scientist, September 2014-present)
A native of the San Joaquin valley, Molly completed her PhD in Ecology at UC Davis in 2007. Her research over the past four years as an Assistant Project Scientist in the Genomic Variation Lab at UCD focused on: native trout population genetics and hybridization, Chinook salmon reintroduction, molecular diversity, and epigenetics; and Yosemite toad conservation genetics and systematics. Molly values interfacing with state and federal agency biologists to answer important species management questions; in the Sexton Lab, she hopes to undertake a greater focus on species plasticity and adaptivity to climate change. Favorite weekend activities include hiking, camping, woodworking, home improvement, and keeping up with her 5-year-old.
Dr. Dannise V. Ruiz-Ramos (Postdoc fellow, May 2017- present)
She is a marine biologist by training and a postdoctoral scholar with the UC Conservation Genomics Consortium working with the Dawson and Sexton labs. Her general interests include [factors influencing] the origins and maintenance of variation in natural populations. At the Sexton lab, Dannise uses environmental DNA to measure biodiversity in vernal pools and to detect threatened plant species. She also contributes to a range of other genomics projects from a search for signals of selection in the sea star Pisaster ochraceous (with the Dawson lab), to the genomics of Colusa grass.
Daniel Toews (PhD candidate, August 2015-present)
Daniel completed his undergraduate degree at the University of California, Merced and is now a PhD student in Environmental Systems graduate program. He’s research range from plant ecology, conservation biology, soil science and wetlands ecology; focusing on the emblematic California Central Valley vernal pools. In his free time he enjoys rock climbing, backpacking, biking and other outdoor activities.
Jorge A. Montiel (PhD candidate, August 2015-present)
Jorge A. Montiel, joining us from Mexico City, is a PhD student in Environmental Systems. He is interested in researching plant adaptation via fungal endophytes and disentangle the mysterious amphibious behavior of vernal pool plants. He obtained his B.S. in Biology from Metropolitan Autonomous University (UAM) and Master’s degree in Life Sciences in Environmental Biology from the Scientific Research and Higher Education Center of Ensenada (CICESE). His interests range from conservation biology, plant ecology, microbial ecology, fungal biology and mediterranean ecosystems ecology.
Lillie Pennington (PhD candidate, June 2017-present)
Lillie Pennington is starting her first year of graduate study in the Sexton lab. She is originally from Oklahoma and earned her B.S. at Oklahoma City University. Lillie is broadly interested in the impacts of climate change on plant communities and is hoping to refine her research goals in a timely manner. In her free time she enjoys shopping, watching movies, and adventuring with friends.
Jackie Shay (PhD candidate, August 2016-present)
Jackie Shay is a systems biologist exploring the symbiosis between fungi and plants. She is currently working on understanding the associations between fungal endophytes of the cut-leafed monkeyflower (Mimulus laciniatus) in response to range limits. Jackie uses an interdisciplinary approach to illustrate plant-fungal friendships in the natural world, quantify the complexities of these relationships, and demonstrate their significance in sustainable agriculture, climate change, and plant evolution.
