Previous fires may hold the key to predicting and reducing the severity of future wildfires in the western United States as fire activity continues to increase, according to researchers from Penn State and the U.S. Forest Service.

Andrew Smye, assistant professor of geosciences at Penn State, will use a $640,000 Faculty Early Career Development Program grant from the National Science Foundation to shed light on a geological mystery while advancing educational opportunities for underrepresented students.
My research utilizes physical experiments, modeling, field work, and remote sensing to better understand (1) the morphodynamics of fluvial, deltaic, and coastal systems; and (2) interactions between vegetation, hydrology, climate, and surface processes. Understanding these complex interactions is essential for predicting landscape change, especially in a changing climate, and requires investigation across a broad range of temporal and spatial scales using a mixture of observational and modeling techniques. The goal is to understand not only how landscapes evolve but also how the processes and process interactions that shape landscapes change under different conditions. Given the rapid warming in the Arctic, much of my work is focused on high latitude landscapes, but I'm interested in morphodynamics, ecogeomorphology, hydrologic connectivity, and coastal change at all latitudes.

Kimberly Lau, assistant professor of geosciences and an associate in Penn State’s Earth and Environmental Systems Institute, received the Pre-tenure Excellence Award from the Geobiology and Geomicrobiology Division of the Geological Society of America. The award recognizes Lau’s accomplishments in the fields of research, mentoring, service and leadership in the geobiology and geomicrobiology community.
In my research, I use novel stable isotope tools to understand climate- and geobiology-related processes that shape our world. During my PhD at Harvard University, I generated triple oxygen isotope records of sulfate minerals to track atmospheric pO2 across the last 550 million years. As an ISEN postdoctoral fellow at Northwestern University, I measured calcium and strontium isotopes across Cretaceous Ocean Anoxic Events to understand marine responses in a high-pCO2 world.
At Penn State, I am an Agouron Geobiology Postdoctoral Research Fellow in the Ingalls group. My research focuses on applying stable isotopes to understand carbonate mineral formation in modern Green Lake. Working in a modern setting allows me to test hypotheses about ancient Earth.
My work focuses on using preexisting fiberoptic cables for seismic sensing in urban environments. By leveraging the dense spatial sampling DFOS systems provide, I can assign magnitudes to seismic signals. Additionally, I apply a deep learning model based on a convolutional neural network to identify low SNR signals. My work has broad application to monitoring enhanced geothermal systems where monitoring and characterizing low SNR microseismicity is crucial to operational safety.
My interests are: Distributed Acoustic Sensing (DAS), Seismology, Geophysics, Machine Learning, Magnitude Estimation, Seismic Inversion, Event detection and localization.
