Lab Members
Assistant Professor of Plant Ecophysiology
Dr. Luiza Aparecido
I am a forest engineer turned plant ecophysiologist. My research focuses on the effects of global change, such as heat, leaf wetness, and herbivory stressors, on plant structure and function. I am lucky to have been able to conduct my work in exciting locations across the tropics, and now I am inspired by desert ecosystems -- natural and urban systems. In addition to my research, I am always happy to share my science through outreach activities (or anybody that is willing to listen). Being a good mentor is what drives me as a professor. My hobbies are hiking, reading, playing with our pets, and building puzzles. Proud to be Brazilian!
Postdoctoral researcher
Dr. Bianca Zorger
Bianca is an ecologist at the Univ. of Utah interested in the effects of climate change and anthropogenic disturbances in plants from individual to community level. Previously, her work has combined plant economic and physiological traits, especially hydraulics traits as descriptors of tolerance to stress and disturbance in a variety of environments in Brazil. During her master she studied the effects of drought and anthropogenic disturbance on the tropical dry forest. In contrast, for her PhD dissertation she explored not only the impact of precipitation fluctuations, but also the vapour pressure deficit and leaf wetting effects on tropical rainforest and montane grasslands. Now, as postdoctoral researcher, she will expand her skills exploring the hydraulic and thermal tolerance of plants to drought and heat of plants in native and urban areas of Utah and Arizona, USA. She was the first person in her family to conclude a course at a public University in Brazil. Now, she intends to inspire and create opportunities to other low-income students to access the University. She enjoys hiking, drawing, trying healthy recipes and spending time with her kid.
Postdoctoral researcher
Dr. Brad Posch
Brad is a post-doc at the Desert Botanical Garden in Phoenix, Arizona. As an ecophysiologist, Brad’s research focuses on understanding the various ways that high temperatures can affect plants from the molecular to the physiological level. This interest began during his PhD project at the Australian National University, where he studied the thermal acclimation of photosynthesis and respiration in wheat under the supervision of Prof. Owen Atkin. This was followed by further work on photosynthetic thermal acclimation during a post-doc with Dr. Nick Smith at Texas Tech. Currently, Brad is leading an NSF-funded research project looking at leaf cooling strategies and thermal tolerance during extreme heat exposure, under the supervision of Drs. Luiza Aparecido, Kevin Hultine (primary mentor), and Ben Blonder. Outside of work, Brad enjoys watching movies, cooking, crosswords, and playing any kind of sport.
PhD Student
Rebecca Senft
Rebecca is PhD student in the School of Biological Sciences at University of Utah. Her research explores the mechanisms that allow invasive plant species to succeed in their non-native environments, with a special interest in acclimation to thermal stress. She is currently studying the physiology of Russian olive, a riparian tree invasive to the Western US. Additionally, Rebecca is passionate about community outreach. During her undergraduate degree, she led multiple events aimed at educating students about biological research happening on campus. In her spare time, Rebecca enjoys the outdoors through activities like kayaking, backpacking, and climbing.
PhD Student
Rafael Freitas, MSc
Rafael is a biologist with a keen interest in plant responses to environmental stresses. He has always been captivated by understanding how plants can live and thrive in arid environments. Currently, he is focused on exploring plant responses to global climate change events, such as heat waves, drought stress, and invasiveness. His research interests stem from his childhood experiences living in arid regions of northeast Brazil and the influence of brilliant mentors with whom he has had the honor to work. In addition to his career as a plant ecophysiologist, he enjoys studying Art History and engaging in outdoor activities. Visiting museums and art galleries are some of his favorite pastimes.
PhD Student
Madeline Buhman, MSc
Madeline is an ecosystem ecologist interested in preserving rangelands and promoting native plants. She has previously worked in the Provo River watershed studying carbon cycling, New Jersey salt marshes studying food webs, and the Chihuahuan desert studying vapor pressure deficit and plant production. Currently she is interested in retaining and encouraging native grass growth in the Utah area, which includes eradicating invasive species such as Russian thistle. When she is not wrangling grass she enjoys good food, bad action movies, and generally being outside.
Undergraduate intern
Lucy Engar
Lucy is a first year undergraduate studying Plant Biology and Geography. She is passionate about the climate and learning how to protect ecosystems, and has a life-long interest and enthusiasm for science. She is super excited about getting more research experience, both in the lab and in the field. In her free time, she likes reading, climbing, hiking, and playing the piano.
Lucy is a Science Research Initiative (SRI) scholar within the College of Science at the University of Utah.

Undergraduate intern
Sydney Gardner
Sydney is an undergraduate at the University of Utah majoring in Earth and Environmental Science. She has always been interested in the outdoors and nature, and she got her start by working and volunteering for AZA accredited facilities in Utah, which she does in her free time. She also loves skiing, traveling, music, and is passionate about public education. She hopes to be able to apply knowledge from the lab to encourage others outside of the college of science to get involved in the outdoors and climate solutions. She is most excited about field work for the lab, but is also looking forward to learning new skills in data analysis and programming.
Sydney is a Science Research Initiative (SRI) scholar within the College of Science at the University of Utah.

Undergraduate intern
Cindy Juarez
Cindy is a senior undergraduate student majoring in Biology. She is passionate about conservation and ecology, and aims to make a positive impact through environmental stewardship. She is very excited about getting more research experience in the lab. In her free time, she enjoys baking, reading, hiking, and playing sports.
Cindy is a 2024 Biology Research Scholar sponsored by the UofU School of Biological Sciences. Her research is in collaboration with the Dr. Ponette-Gonzalez lab at the Natural History Museum of Utah.

Undergraduate intern
Brandt Winn
Brandt is a long-time undergrad Biology student with an emphasis in Ecology, Evolution, and Environment. Born and raised locally in Eagle Mountain, he has personally seen how climate change and human development has affected the climate and the local ecosystem of his hometown even in just a short time frame. Originally starting school to go into medicine, he changed his mind after captivating classes on topics of conservation, ecology, and plant biology. He has always been a lover of the outdoors ever since being in The Scouts and wants to keep the outdoors beautiful and extend that love and mindset to his biggest passion in life, solving problems: specifically anthropogenic climate change. His ultimate goal is to collect and consolidate data on anthropogenic climate change to educate and advocate to businesses, political officials, and the public as a science communicator, influencing sustainability efforts to restore the earth's natural carbon cycle. He is enthusiastic about his involvement in the Aparecido lab, where research on invasion ecology and plant ecophysiological responses will provide insights into future scenarios if current trends persist, therefore driving policy and action. In his free time, he likes to cook, bake, play video games, camp, study French, volunteer, and participate in performance arts like dancing, color guard, theater, and more.
Brandt is a Wilkes undergraduate research scholar.
