The Department of Biological Sciences is home to several research laboratories. Laboratory work ranges from the molecular to the organismal scale. Check out the individual labs below:
Applied Plant Sciences Laboratory – (Dr. Jonathan Willis) The Applied Plant Sciences Lab conducts research intended to enhance the success of coastal restoration and management efforts, environmental assessments, and phytoremediation applications. Research needs in these focus areas are addressed using a combination of techniques from the fields of plant ecophysiology, pollution ecology, and multivariate statistical analysis.
Aquatic Ecology and Astacology Laboratory – (Dr. Chris Bonvillain) Research in the Aquatic Ecology and Astacology Lab focuses on the ecology and biology of Louisiana crayfishes and aquatic ecosystems. Research efforts assess ecological functions of aquatic habitats, the effects of physical and chemical habitat characteristics on aquatic biota, physical and physiological responses of aquatic biota to environmental hypoxia, changes in physicochemistry and biotic communities due to natural and anthropogenic influences, and distribution, life history characteristics, and diversity of crayfishes throughout the state.
Bayousphere Research Laboratory – (Drs. Allyse Ferrara and Quenton Fontenot) The Bayousphere Research Lab has its roots in fisheries but has expanded into coastal restoration. A large part of our fisheries research involves fish ecology within the upper Barataria Estuary. We use the Nicholls Farm to cultivate several species of plants that are used for restoration activities.
Environmental Biotechnology Laboratory – (Dr. Raj Boopathy) Research topics include biological treatment of wastewater, bioremediation of hazardous chemicals including explosives and oil spills, survey of antibiotic resistant bacteria in Bayou Lafourche and sewage treatment plants, lignocellulosic ethanol production, and antimicrobial properties of spices.
Gar Laboratory – (Dr. Solomon R. David) The #GarLab uses conservation biology and fundamental ecological principles to investigate patterns in life history, biodiversity, and evolution of species at multiple scales, and how these patterns can inform restoration and management of aquatic natural resources. We are particularly interested in the ecological roles of peripheral and migratory populations of species; these populations may be more susceptible to perturbations such as habitat loss, invasive species, and climate change. Fishes serve as our primary model organisms, including, but not limited to, the gars (Lepisosteidae). Additional collaborations include genomics and fishery management of “ancient sport fish” and sustainable aquaculture. We also use science communication and social media to raise awareness of the value of aquatic ecosystems and freshwater biodiversity.
Hollander Laboratory – (Dr. Aimee Hollander) The Hollander Lab studies environmental reservoirs for human pathogens as well as antibiotic resistance trends in the human pathogen Neisseria gonorrhoeae and bacteria that cause urinary tract infections. In addition to detecting pathogens and antibiotic resistance, we are also identifying transcriptional regulators that increase pathogen virulence as well as molecular mechanisms for antibiotic resistance.
Infectious Diseases Laboratory – (Dr. Raj Nathaniel) The IDEAL lab studies epidemiology of MRSA, anthropomorphic markers as measures of water quality, innate and adaptive immune responses in vertebrate and invertebrate animals, and characterization of vibrio-phages.
LaFleur Laboratory – (Dr. Gary LaFleur) We look at several different methods for monitoring environmental health by measuring distinct biomarkers in a range of estuarine species. Projects include the characterization of reproductive proteins in fish, surveys of the Maculata Apple Snail in the BTES, conducting frog call surveys every spring, and using unmanned aerial systems to collect images of barrier island vegetation.
Wetland Ecology Laboratory – (Dr. Sean Graham) The overall aim of the Wetland Ecology Lab is to gain a better understanding of (1) the functional role of plant-soil systems in wetland environments, (2) how global changes and environmental perturbations influence wetland ecosystem structure, function, and stability, and (3) how to optimize wetland restoration techniques so that ecosystem function is maintained and enhanced. In doing so, our research combines basic ecology with applied science to answer fundamental questions that address natural resource management concerns.
Zou Laboratory – (Dr. Enmin Zou) The Zou lab studies how aquatic invertebrates, primarily crustaceans, function under normal conditions and under chemical stress. Current efforts center around the elucidation of hormonal control of crustacean molting and mechanisms for molting disruption by xenobiotics.
