- » More about David Bailey
"Ahoy! I’m David Bailey and I obtained a Bachelor of Science in Geoscience with a focus in GIS, from Tennessee Tech University in 2014. I then enrolled as one of the first batch of students in the newly created PSM program and acquired a Master’s in Environmental Informatics in 2016 from TTUs School of Environmental Studies.
Since then, I’ve performed various GIS related work with prospective political campaigns, undertaken entrepreneurial challenges of creating a business, and work as the GIS Systems Manager for the City of Cookeville, where I’ve been since 2019. The day to day involves maintaining the city’s GIS databases and the access to and sharing of data, creating and building apps, and performing various analysis typically pertaining to city planning which provides better information for decision making. In addition to that, I am also the city’s drone pilot. We have recently purchased a new drone and utilize it quite heavily for aerial mapping and general photo/video acquisition for project updates.
Tennessee Tech, and especially the faculty of the Earth Sciences Department, provided a great deal of knowledge and confidence which undoubtedly helped me to get to where I am now." David Bailey

- » More about Isaac Hollingsworth
Isaac Hollingsworth graduated from Tennessee Tech with a Bachelor of Science in Geosciences with a concentration in Geographic Information Systems. He later returned to Tech to complete a Professional Science Master’s in Environmental Informatics.

"My path into GIS actually began before coming to Tennessee Tech. I served as a Geospatial Engineer in the U.S. Army, where I was introduced to professional cartography, terrain analysis, and geospatial intelligence. After leaving the Army, Tennessee Tech gave me the opportunity to build on that experience and develop a much stronger foundation in geoscience, GIS, remote sensing, and research.
While at Tech, I had the opportunity to work as a GIS teaching assistant and participate in several research projects, including lunar mapping and planetary geospatial research. Those experiences ultimately helped turn what had been a career in GIS into an interest in applying geospatial science to planetary exploration.

Today, I work as a Geospatial Scientist supporting NASA’s Johnson Space Center in Houston, Texas. My work focuses on applying GIS and cartography to human lunar exploration, including the development of geospatial datasets, terrain analysis, mapping standards, and operational map products used to support Artemis mission planning, training, and simulations. It has been especially rewarding to see skills I developed through projects at Tennessee Tech translate directly into work supporting future exploration of the Moon.
Tennessee Tech played an important role in getting me where I am today. The opportunity to work closely with faculty, participate in research, teach GIS, and take on projects beyond the classroom gave me experience that I continue to draw from professionally. My biggest advice to current students would be to take advantage of those opportunities. Get involved with research, build things, work with your professors, and don’t be afraid to pursue an unconventional application of your degree. GIS and geoscience can take you into fields and places you may not initially expect." Isaac Hollingsworth

- » More about Rowan Freeman
“Hello, my name is Rowan Freeman and I attended Tennessee Tech between 2000 and 2004, graduating with a Bachelor of Science in Geology with a Geographic Information System focus. I headed to New Jersey shortly after and started my career as a contaminated land specialist and consultant, and after nearly six years there, I moved to New Zealand where I have resided ever since.
“My academic foundation at Tennessee Tech prepared me to fulfill several very rewarding professional roles which have largely involved contamination characterization, remediation, management, and monitoring, across a range of site types (including but not limited to brownfield, superfund, oil refinery, power generation, former gasworks, property development, and municipal). Ultimately, my work has been focused on assisting clients to fulfill their obligations to protect human and environmental health, whether driven by regulatory forces or for their own peace of mind.
“I have also recently obtained my Master of Science in Environmental Science and I am a Certified Environmental Practitioner (Site Contamination) under the Environment Institute of Australia and New Zealand scheme. My positive experience at Tennessee Tech, especially across the topics of geology, soil science, and general chemistry laid the foundation for my professional achievements to date and so far, it has been an awesome trip!” Rowan Freeman.

John Corley
B.S. Geosciences
Currently a registered professional geologist at the Missouri Geological Survey.
- » More about John Corley
"Hello! I’m John Corley, and I am proud to call myself an alumnus of the Tennessee
Tech Earth Sciences Department (’11). The Tennessee Tech Earth Sciences Department
has a rich tradition of laying down a substantial foundation of a broad range of geologic
fundamentals, which translates into success in the workplace. The quality of education
you get at the department is reflected in the history of the students’ successes Tennessee
Geoconclave.
"I am currently a registered professional geologist at the Missouri Geological Survey,
which is a division of the Missouri Department of Natural Resources. Our state survey
is special because it not only handles typical geologic survey duties such as mapping
and research, but my group also performs regulatory oversight. My day-to-day job as
an environmental geologist encompasses so many aspects of geology. We oversee the
design, installation, and review of groundwater and gas monitoring networks for sanitary
landfills; we conduct geologic and hydrologic evaluations of existing and proposed
wastewater treatment facilities including earthen storage basins, land application
sites, and mechanical treatment plants as part of their permitting process – this
also includes performing stream evaluations to determine losing or gaining classifications;
and we perform investigations related to geologic hazards such as sinkholes and landslides,
and remediation support for concerned citizens."Field work is performed on a weekly basis,and we have state-wide jurisdiction so I get to see all of Missouri’s rocks and wide variety of landscapes. Each day is different, which keeps me on my toes. Before my current job, I worked in water pollution enforcement and compliance. In this day and age, having a working knowledge of how to read and interpret rules and regulations will help you in not only your professional career (whatever that may be), but also help you in your personal life in helping you become a more informed citizen in regard to how rules and regulations are made – and how you can provide feedback and help change them.
"My feedback for potential or current students of the program: ask your professors
if they need help with a research project! Get out of your social comfort zones! Go
on all the school field trips! Go hiking, caving, or kayaking! The greater Cookeville
area has some world-class waterfalls and caves, so study hard and enjoy a well-deserved
break exploring Mother Nature and fully enjoying your current time and space at Tennessee
Tech. Because you never know where life will fling you, but I hope you enjoy your
journey along the way," John Corley.

I cherish the memories of teaching lab, going on local and international field trips, and getting to know the amazing close-knit faculty and my peers. As I look back on the support and memories during my undergraduate studies, I would have not changed a thing. The courses I took gave me a framework and understanding of geologic fundamentals that I used in graduate school and now in my career as a Lead Geoscientist at Ovintiv.
"After graduating from Tennessee Tech, I studied at the University of Kansas where I obtained a Master of Science in Geosciences. I defended my thesis in 2014 titled, “Fluvial to shelfal strata of the Late Cretaceous to Paleogene Dorotea and Tres Pasos Formations, Magallanes Basin, El Calafate, Argentina.” From Kansas, I went to work for Encana/Ovintiv in Denver, CO where I still work to this day. Since working at Encana/Ovintiv, I’ve worked multiple assets and basins in development and planning, explored North American plays, and now managing a team.
"Tennessee Tech shaped me into who I am today, and I am proud to be an alumnus. Without the caring nature of the professors and great education at Tennessee Tech, I do not know where I would be," Michael Waynick
