Research Staff


Bryan Page, MS

Bryan completed his undergraduate degree at Slippery Rock University in 2009. During that same year, he started working with BioMost, Inc. of Mars, PA. While at BioMost, Inc., Bryan worked with public and private clients on designing, operation, and maintenance of mine drainage passive treatment systems, along with other environmental services. In August 2014, he began his Master of Science in Environmental Science at the University of Oklahoma. His research focused on the hydraulic conductivity of vertical flow bioreactors. Bryan graduated from OU in December 2016.

Graduate Students


Juan Arango Calderon
PhD student, Environmental Engineering

Juan has a Bachelor of Science in Environmental Engineering and Master of Science in Civil Engineering, Water Resources from The University of Oklahoma. His current research focuses on using remote sensing technology to develop models capable of determining water quality parameters.

 


Brandon Holzbauer-Schweitzer
PhD student, Environmental Science

Brandon received his undergraduate degree in Environmental Geoscience from Winona State University in 2014. He then moved to Oklahoma and began his graduate work, which focused on utilizing low impact development (LID) best management practices (BMPs) as alternatives to traditional urban stormwater management. He is now working on his doctoral research, which uses drones to evaluate habitat quality and predict surface water quality. In his free time, Brandon enjoys eating, watching sports, and, when the sun isn't shining, the wonderful Oklahoma weather.


Derrick Nguyen
MS student, Environmental Engineering

Derrick is from Oklahoma City, OK and earned his Bachelor of Science in Environmental Engineering at The University of Oklahoma. He is currently working on his Master's degree at OU. He is an avid Thunder basketball fan. Derrick also enjoys hiking and photography, a hobby he recently picked up.


Nicholas Shepherd
PhD student, Environmental Engineering

Nick was raised in Miami, OK near the Tar Creek Superfund Site, and he has been working on Tar Creek related research projects since his sophomore year of high school. His high school work led to working for CREW as an undergraduate research assistant, where he received a BS in Environmental Engineering and his MS in Civil Engineering, Water Resources . His masters research investigated the benefits of Castor canadensis (North American Beaver) when repopulating a mine drainage impacted stream.


Amy Sikora
MS student, Environmental Engineering

Amy was born and raised in Calgary, Alberta, Canada. She completed her Bachelor of Science in Environmental Engineering here at The University of Oklahoma. She is continuing at OU to get her Master's degree. Amy enjoys flower gardening and spending time outside in her spare time.


Zepei (Maggie) Tang
PhD student, Environmental Engineering

Maggie is from China and spent two years in Scotland. She moved to Pittsburgh to earn her Master's degree from Carnegie Mellon University. She is now at The University of Oklahoma working on her Doctoral degree. Maggie's current work consists of looking at the relationships between metals and nutrients at the sediment-water column interface in a large multi-use reservoir.


Tiffany Verlander
MS student, Environmental Science

Tiffany is from Tulsa, OK, and is a first year graduate student at OU. She obtained her undergrad from Northeastern State University in Biology with a Wildlife and Fisheries Emphasis. She also acquired a certificate in Geographic Information Systems from Tulsa Community College, and was most recently a GIS Research Assistant intern at NASA's Jet Propulsion Laboratory. In her spare time she enjoys travel, art, hiking, and has a passion for natural sciences.

 

 


Taylor Wall
MS student, Environmental Engineering

Taylor is from Tuttle, Oklahoma. She received her Bachelor of Science in Environmental Engineering from OU in May 2017.
