Featured Students

Kavina Eksteen

Kavina Eksteen has completed a Bachelor of Science degree with majors in Zoology and Physiology at the University of KwaZulu-Natal, and an honours degree in Environmental Management from the University of South Africa. She is currently a Master’s student in the Environmental Science Graduate Program at Oklahoma State University. Her master’s thesis is focussed on water quality in the Lake Hudson Watershed in Mayes County, Oklahoma. Research components include 1) a riparian assessment prioritization scheme of the watershed, 2) pollutant loads and load reduction modelling with EPA’s STEPL model using riparian buffers as a best management practice, and 3) the economic costs linked to buffer implementation in critical areas of the watershed.



Stephen Angle

An invasive plant species, yellow floating heart (Nymphoides peltata), has successfully colonized Lake Carl Blackwell. Stephen's research is a management-based approach studying the efficacy of herbicide treatment targeting this invasive species over time. His monitoring methods include using unmanned aerial vehicle (UAV) imagery and multispectral satellite imagery to track the spatial extent and health of yellow floating heart. UAVs allow for very fine resolution imagery for improved detection accuracy, while satellite data allows for normalized difference vegetation index (NDVI) calculation. The objective of the research is to use these remote sensing tools to determine how the infestation is temporally changing, which will then aid in management decisions moving forward.

Stephen Angle received his B.S. in Environmental Science from Oklahoma State in Spring 2017. His favorite activities are fishing, kayaking, hunting, and watching Thunder games. Stephen’s career interests include water quality monitoring, watershed planning and restoration, and geographic information systems (GIS) of natural resources. Stephen is an active volunteer in the Oklahoma Conservation Commission’s Blue Thumb stream monitoring program and the current president of the Society of Environmental Scientists.


Lexi Freeman

Lexi is conducting field surveys of the federally endangered American burying beetle (Nicrophorus americanus) at Camp Gruber Training Center located in northeastern Oklahoma to determine if the carrion beetle utilizes the same habitat throughout the season. This research will provide a better understanding of how the species, which plays important ecological roles in scavenging and recycling decaying organic matter, utilizes a patchy environment.  Her results will inform conservation and recovery plans for this species.

Lexi earned her Bachelor’s of Science in Zoology at Oklahoma State University in 2016. Currently, she is pursuing a Master’s degree in Environmental Science while conducting research through the Department of Entomology and Plant Pathology under Dr. Wyatt Hoback. She is a member of the Citizen Potawatomi Nation. The ESGP works closely with the Center for Sovereign Nations, which made the ESGP program especially appealing in this regard. Additionally, Lexi feels that Dr. Stoodley "has been an incredible instructor and resource throughout the entire graduate program experience."

She says, “Ultimately, my goal is to return to tribal nations and help with the implementation and regulation of environmentally friendly practices. As a Native American I feel a close kinship to nature and respect and admire the work tribal nations do to preserve their natural surrounding and wildlife. I appreciate and believe in the Native American philosophy of seven generations. 'In every deliberation, we must consider the impact on the seventh generation.' I’ve thoroughly enjoyed my experience at Oklahoma State University as an undergraduate and wished to continue as a Cowboy into the Environmental Science graduate program.”

Lexi's goal of assisting her tribe with environmental issues will soon be realized: she was recently offered a position as Environmental Specialist with the Citizen Potawatomi Nation.


Justina Da Costa Belo 

Justina Da Costa Belo is a Fulbright scholar from East Timor, one of the newest countries in Southeast Asia. She finished her undergrad degree in the Philippines, earning a Bachelor of Science in Environmental and Sanitary Engineering. Currently, she is pursuing a Master’s degree in Environmental Science, focusing on watershed management. Here is what Justina has to say about her experiences at Oklahoma State University:

“In 2016, the Institute of International Education (IIE) helped me contact my academic advisor, Dr. Scott Stoodley, who is an expert in water and watershed management. As Dr. Stoodley’s student, I get the opportunity to be exposed to various aspects of environmental science and be able to solve environmental problems from social, environmental, and economic perspectives.

“During the first year of my study at Oklahoma State University, I joined the International Student Organization (ISO) as an intern on the cultural committee. This year, I am actively involved in several organizations: the Fulbright Scholar and Student Association (FSSA), Society of Environmental Scientists, Phi Kappa Phi Honor Society, and Phi Beta Delta International Honor Society.

“OSU is an academically diverse land-grant institution that challenges me to be a better scholar and helps me broaden my horizon as an international student. I am glad that I came to OSU and became a member of the Cowboy family. Go Pokes!”

Michael Thayer, PhD

Dr. Thayer completed his Ph.D. in the spring and has re-joined the ESGP as an adjunct instructor. His dissertation research focused on Environmental Management Systems (EMSs), such as ISO 14001 and EMAS, which are used by many organizations across the globe, with the overarching goal of continual improvement of environmental performance. Proponents claim that properly implemented, supported, and maintained EMSs will result in many organizational benefits; detractors claim EMSs are more akin to “greenwashing” and do not provide much in the way of organizational benefit. The most important and the most difficult piece of the EMS process is the identification of significant environmental aspects. The Aspect-Impact-Mitigation (AIM) Prioritization Program was originally developed to provide a holistic risk-based approach to identify significant environmental aspects in accordance with the guidance in the ISO 14001 standard. While the current version of AIM orders environmental aspects by relative risk (i.e., significance), it is not without its own shortcomings. Dr. Thayer's research resulted in an improved AIM approach for identifying significant environmental aspects through assessment of environmental impact risks and prioritized mitigation potentials.

Keima Kamara, MS

"Thank you for giving me the opportunity to complete my Ms degree in this wonderful program. Choosing the Environmental Science Graduate Program at Oklahoma State University is one of the best decisions I have ever made in my entire life. I have grown so much in my career as an environmental scientist. With wonderful people like Dr. Scott Stoodley I got to believe in my self and never to choose failure as an option. But rather to work harder in order to achieve my dreams and turn them into reality."- Keima Kamara

Keima is currently working as a Solid Waste Assistant Extension Specialist with the Oklahoma Cooperative Extension Service.


Aniko Konya, Visiting Scholar

Aniko Konya, Ph.D. student from Hungary, arrived in Stillwater during a tornado warning. Read about this and other educational experiences she enjoyed during her five months as a visiting scholar to OSU.


Sally Kheirandish, MS student

Sally is conducting research to develop an aeration diffuser system which employs a simple O-ring regulator to provide the oxygen necessary for effective activated sludge or water treatment. Her experiments manipulate air pressure and airflow rate to a disc diffuser which is immersed in a water tank. She uses regulators with varying O-ring hardness and observes the resulting width of the bubble plume generated by the diffuser. Sally's analysis characterizes vertical mixing of the water column based on bubble plume geometry to determine the optimal airflow. Her results will be useful in designing water treatment techniques that are both energy efficient and cost effective.

Sally received her bachelor's degree in environmental engineering from the University of Tehran in 2007 and spent the next decade working for engineering consulting firms in Iran in the fields of environmental planning, environmental assessment and natural resource management. She says studying at Oklahoma State University is one of the greatest experiences she has had during her academic career. Sally states, "Not only did I learn new scientific principles and methodologies to understand and analyze environmental problems, but also I met other students from around the world which helped me strengthen my international mindset," and she thanks her advisor Dr. Scott Stoodley "for his unwavering support and helpful advice" during her graduate program.

Abubakarr Mansaray, Ph.D. student

Abu Mansaray learned about Oklahoma State University through a network of former OSU students who conducted research at Njala University in Sierra Leone, where Abu earned his MS degree in Environmental Chemistry.

Abu’s research uses remote sensing imagery of the Grand Lake, Oklahoma, watershed and in situ water quality measures to develop algorithms which can be used for predictive modeling. By combining Landsat's multispectral reflectance bands with temporally coincident water quality parameters, Abu is developing tools to assist managers in monitoring reservoir ecosystems and forecasting trends, such as imminent pollution spikes that lead to algal blooms. Abu’s advisor is Dr. Scott Stoodley.

As a volunteer with the Oklahoma Blue Thumb program, Abu assists with monthly monitoring of Stillwater's Feather Creek.  He serves as student board member of Oklahoma Clean Lakes and Watersheds Association (OCLWA) and is active in OSU’s Fulbright Students & Scholars Association and the university's African Students Organization. Abu is also President of the Society of Environmental Scientists, a multi-disciplinary organization of graduate students who are interested in environmental sciences and related issues.
