Faculty

Kiona Ogle

I am a professor in the School of Informatics, Computing, and Cyber Systems (SICCS) at NAU, and I am an affiliate faculty member in the Center for Ecosystem Science and Society (Ecoss) and the Department of Biological Sciences. I am also the T3 Program Director. My research and teaching employs an integrative approach that merges ecology, statistics, mathematics, and computing, with the aim of understanding and predicting how plants and ecosystems are affected by, or respond to, environmental perturbations such as those associated with climate change.

Research Faculty

Ana Miller-ter Kuile

Ana is a Postdoctoral Scholar in SICCS working with Dr. Kiona Ogle. She received her Ph.D. in Ecology from UC Santa Barbara and her B.S. in Earth Systems- Biosphere Track from Stanford University. Her general research interests include modeling and understanding how biological communities are impacted and respond to anthropogenic change, including species introductions and losses, invasive species, habitat change, climate change, and restoration efforts aimed at reversing or directing these changes. Ana has a background in community ecology and combines field, laboratory, and computational approaches in her work. She is also a Software Carpentries instructor and has training and experience with equitable STEM and data science education through an NSF-AGEP Hispanic Serving Institutions Teaching Fellowship and the Environmental Data Science Inclusion Network.

Postdoctoral Researchers

Brandon Strange

Brandon is a postdoctoral scholar in SICCS working with Dr. Kiona Ogle. He earned his doctorate in Natural Resources and Ecohydrology at the University of Arizona in the School of Natural Resources and the Environment as well as the Laboratory of Tree Ring Research in 2023. His research interests are broadly centered on understanding how anthropogenic climate change impacts forest vitality and function and how this in turn impacts the terrestrial carbon cycle. He uses a variety of techniques for this research including stable isotope biogeochemistry, dendrochronology, and ecophysiological approaches. Brandon’s background also includes training in paleoclimate, eddy-covariance techniques, xylogenesis, and climate-vegetation feedbacks on various spatiotemporal scales. He is currently working on an NSF Macrosystems Biology project quantifying how climate extremes impact forest function on various timescales using tree rings, eddy-covariance fluxes, and stable isotopes within a Bayesian modelling framework.

Graduate Students

Abraham Cadmus

Abraham is a PhD student in Biology at NAU and National Science Foundation Graduate Research Fellow. Abraham is interested in providing the community with pragmatic solutions that will help mitigate negative affects on Biodiversity in the increasingly dynamic environments of the Southwest. He is currently working on synthesizing common garden experiments and field measurements of plant physiological processes, to create predictive models that can be used to inform restoration projects of best practice. Email Abraham for more information.

Volodymyr Saruta

Volodymyr is a PhD student in the Informatics and Computing program in the School of Informatics, Computing, and Cyber Systems at NAU. His research is primarily focused on terrestrial  ecosystem carbon cycling. In this work, Volodymyr has used a variety of statistical and process-based modeling approaches. Currently, Volodymyr is working on modeling and understanding controls on soil CO2 fluxes using process-based models of soil CO2 production and transport. Volodymyr plans to apply emulation (meta-modeling) techniques to enable faster application of such process based models and for informing such models with data. Email Volodymyr ("Vova") for more information.

Emma Reich

Emma is a PhD student in the T3 program in Ecological and Environmental Informatics in the School of Informatics, Computing, and Cyber Systems at NAU and a NASA FINESST recipient. They study plant ecophysiology and ecosystem water fluxes in drylands, and are developing an evapotranspiration partitioning model with eddy covariance flux tower data using both process-based and Bayesian approaches. In 2019 they graduated from UC Berkeley with a BS in Molecular Environmental Biology and a concentration in Ecology, where they studied blue oak hydraulics and crustose coralline algae susceptibility to rising temperatures.

Alicia Formanack

Alicia Formanack is a second-year PhD student in Kiona Ogle’s Ecological Synthesis lab. Alicia is interested in tree physiology, ecological memory, and how climate change is affecting forest growth and mortality. She completed her Masters in Biology at the University of Central Florida in Dr. Sasha Hararuk’s Ecoinformatics Lab. As a masters student, she developed an individual-based model of tree growth and mortality to determine which pine species would have the highest carbon uptake and storage potential for a given geographic location and timeframe.
