Biography of Dr. Antonietta Quigg

Phytoplankton ecophysiology, physiological adaptation, photosynthesis, biological oceanography, biochemistry and biophysics, molecular biology, plant physiology, evolution (look around the website for more specific information).

Teaching Philosophy:

Teaching remains both one of my greatest challenges and one of the most rewarding aspects of my position. I endeavor to inspire students with my enthusiasm for the subject matter, foster critical-thinking and decision-making abilities with examples and innovative testing approaches as well as encourage students to become active and competent learners outside the classroom. At a campus dedicated to marine studies, undergraduates arrive eager to learn about marine mammals and fisheries science, but rarely consider the role of phytoplankton and marine plants (seaweeds, seagrasses, marshes) as the base of food webs. Teaching Marine Botany, a core course taken predominately by juniors and seniors, is my chance to bring them towards the “light”. By blending traditional and contemporary topics (e.g. eutrophication, climate change, invasive species) I provide students with tangible examples from their daily lives. This is often when the light bulbs are triggered, and I will pause lecturing to talk/debate/stimulate students along a line that has clearly caught at least some of their attention. Part of my philosophy is to also lead by example: hard work, dedication and persistence in performing of research and presentations, participation and publication, as key for success in science. The other part is participation: my students and I have a strong bond forged from many days at sea (>100), as well as time in the field and laboratory. I have had >40 undergraduates work in the laboratory, 14 graduate students and 5 postdoctoral fellows. One of the advantages to being on a small campus is that teaching-related activities are indeed not limited to the classroom, but occurs in the hallways, offices and open spaces around campus.

Project

My research interests primarily focus on phytoplankton ecology in Galveston Bay. We have been working together to determine how the phytoplankton community changes in response to variations in the flow of freshwater into Galveston Bay. We recently published a paper in Frontiers in Marine Science, pertaining to the response of the microbial community in Galveston Bay following the extreme flooding event that was produced by Hurricane Harvey.  Another aspect of phytoplankton research I am involved with includes using an Imaging FlowCytobot to monitor for harmful algal blooms in Galveston Bay. We work in conjunction with Texas Parks and Wildlife and the Texas Department of Health and Safety to monitor for harmful species of phytoplankton that can produce toxins which can accumulate in finfish and shellfish which if consumed by can have deleterious effects on human health.

I also teach the Succeeding in Science course (MARB101) which is an introductory course in the Marine Biology department to familiarize students with the fields of Marine Biology and Marine Science. In this course, we discuss various career options in these marine fields as well as learn some basic sampling techniques commonly used in these disciplines. To learn more you can visit the TAMUG – Sea Camp YouTube channel to watch some of our class activities including: bag seining, a trip around Pelican Island on the R/V Earl Milan, water quality testing and more.

Project

 Hi! I graduated with my B.S. in Marine Biology from Texas A&M University at Galveston in May 2020.  I am currently a Ph.D. student co-advised by Dr. Quigg and Dr. Rooker in the Marine Biology IDP. My research interests include ecosystem-level interactions, stable isotope analysis, and integrating these two subjects to ask questions about an evolving environment due to climate change. I hope to design my dissertation to look at isotope fractionation and transfer through several trophic levels in the context of rising sea surface temperatures and ocean acidification and applying Compound Specific Stable Isotope Analysis of Amino Acids for analysis.

Project

I graduated from Colorado College in 2017 with a Bachelor’s degree in Biology (organisms, evolution and ecology track). I am currently a PhD student working on quantifying persistent man-made chemical pollutants, specifically PFAS compounds, in water and biota from Galveston Bay following the Deer Park ITC Fire. As a part of this work, I will also use bioinformatics to attempt biomarker discovery and to create models that will aid in further understanding an organisms adaptive potential under stressful environmental conditions. My other projects include PAH and PCB detection in fish, water and sediment samples, along with Dioxin analysis in dolphin blubber.

Project

Hello! Prior to joining the Phytoplankton Dynamics Lab in August 2020, I received a B.S. in Marine Science and Biochemistry at Coastal Carolina University. My current research interests include understanding how emerging pollutants impact aquatic ecosystems, specifically regarding their presence and levels in vulnerable systems, determining their impact on primary productivity, and understanding human perception of emerging pollutants. My current project works to identify how emerging pollutants impact primary producers by assessing how the emergent pollutant class, perfluorinated alkylated substances (PFASs), impacts phytoplankton physiology and phytoplankton community diversity. PFASs have been used ubiquitously by humans and are now found in environments around the world. PFASs can be toxic, bioaccumulate, and are persistent, so it's important to determine their impact on aquatic primary producers which fuel the rest of the aquatic environment.

Hello there! I graduated from Texas A&M University at Galveston in 2018 with a B.S. in Marine Biology and a minor in Diving Technology and Methods. I held a research assistant position here in the Phytoplankton Dynamics Lab from my graduation until I began by Master’s degree in August 2021. My Master’s research project focuses on relationships between water quality and phytoplankton biomass and community structure in Galveston Bay. Using image data collected by IFCB (Imaging FlowCytobot) and a manually trained automatic classifier program, this research aims to analyze a seven year dataset looking at community dynamics surrounding seasonal variation, Harmful Algal Bloom (HAB) formation, and severe weather events including flooding caused by Hurricane Harvey in 2017. With increasing frequency of HAB formations and severe weather events, analysis of how the phytoplankton community of Galveston Bay react in response to these events is critical to maintaining the health, safety, and productivity of the ecosystem.

Undergraduate Research Assistant



Howdy! I have been an undergraduate student researcher here in the Phytoplankton Dynamics Lab since Spring of 2021 and have spent time as a volunteer, lab technician, fellow, and most recently, research assistant. I am currently pursuing my undergraduate degrees in Marine Biology as well as Marine Fisheries. My areas of interest involve ecology, toxicology, and conservation of coastal and estuarine ecosystems. I am currently conducting research under the guidance of Ph.D. student, Sarah Davis.

My research project involves studying the impact of PFOS, a toxic, persistent pollutant, on natural phytoplankton communities found in Texas coastal ecosystems. I am currently working on my undergraduate thesis over this research, which will be available for public access following a 2 year embargo, in the meantime I plan to co-author publications relevant to the research I have been working on under Sarah along with my undergraduate colleagues Alexis Mitchell and Chris Pryor.





Christian Pryor

Undergraduate Researcher



Hello! I joined the Phytoplankton Dynamics Lab in the Fall of 2022 as an undergraduate researcher. I am currently pursuing a B.S. in Marine Sciences with a minor in chemistry. My research interests include microbial biogeochemistry and aquatic primary productivity.

My first year in the lab, I worked with Sarah Davis to assess the impacts of Per- and Polyfluoroalkyl Substances (PFASs), a class of persistent man-made chemicals, on Texas Coast phytoplankton. My project investigated the physiological toxicity of 6:2 Fluorotelomer Sulfonate (6:2 FTS) , a non-toxic substitute for bioaccumulative and toxic PFASs. The growing use of 6:2 FTS and a lack of knowledge on its aquatic toxicity make studies like ours necessary. Since completing my 6:2 FTS project, I am now designing an undergraduate thesis that examines bacteria-phytoplankton interactions.

Howdy! I am a sophomore currently volunteering in the Phytoplankton Dynamics lab. I monitor harmful Algal Blooms (HABs) in Galveston Bay through our Imaging FlowCytobot (IFCB). The IFCB uses a combination of flow cytometric and video technology to capture high resolution images of suspended particles. The process involves collecting specimen samples, filtering for Chlorophyll-a, focusing images captured on​ the​ IFCB, and evaluating these images of phytoplankton cells to determine the presence of HABs. I will graduate in the Spring of 2025 with a double-degree in Marine Biology and Marine Fisheries. My personal interests include plant ecology, molecular biology, conservation of marine ecosystems, and invertebrate zoology.

Project

Yes, it's me again! I currently have a few different roles in the lab. I started working in a phytoplankton physiology lab after I received my Bachelor’s degree in 2015. Most of the research I have been involved in up until this point has focused on the Deepwater Horizon oil spill of 2010 and the effects it had on the microbial community.  As a research Associate, I am helping with a Texas General Land Office funded project aimed at studying the effects of perfluorinated alkylated substances on phytoplankton in Galveston Bay. As the Lab manager, I am responsible for maintaining lab equipment, keeping the lab stocked with supplies, and helping the other lab members with anything from logistics to data analysis. I have also recently decided to go back to school part time working towards my master’s degree in Marine Biology- see my profile above for more details on that project!
