Our Team

Allan Bacon, Principal Investigator

The goal of Allan’s research is to unravel the complex natural and human dimensions of soil formation, and to use this information to better understand the processes and improve management of Earth’s surface. His current focus is on biogeophyisical processes of subsoil, drivers and implications of parent material variation on depositional landforms, and regional pedogenic and anthropedogenic interactions in the southeastern United States. Before joining the Soil and Water Sciences Department at the University of Florida Allan received a B.S. in Forestry from Northern Arizona, a Ph.D. from Duke University for his dissertation titled “Pedogenesis and Anthropedogenesis in the Southern Piedmont, and was a postdoctoral Research Associate in the School of Forest Resources and Conservation at the University of Florida.

Julio Pachon, M.S. Student

Julio is redefining how we think about soil texture. He is using laser diffraction methods to quantify the particle size distribution of more than 2000 soil and subsoil samples from the PINEMAP Tier II Network. Julio’s work not only reveals how pedogenic gradients across the southeastern United States influence soil particle size distribution, but also how soil particle size distribution controls Earth surface properties and processes (including traditional soil biogeochemical properties, visible near infrared spectral properties, and even forest ecosystem C and N response to management). Before joining our lab Julio earned a B.S. from Cornell University where he majored in the Science of Natural and Environmental Resources and minored in Soil Science.


Kayci Kowalski, majoring in Soil and Water Science


Joshua Butterick, majoring in Civil Engineering

Kayci and Josh are critical members of our research group. In addition to providing support for day to day field and laboratory work, they are currently working with the PINEMAP Tier II soil archive to measure then visible near infrared spectral properties of soil and subsoil across the southeastern United States.
