Dr. Quigg, Professor and Associate Vice President for Research and Graduate studies at Texas A&M University at Galveston. Since starting at A&M in 2003, she has participated in 42 research proposals (>21 million), acting as lead PI on 27 including the present project (>10 million).  This has led to >70 publications, most of which have students and postdocs at lead authors.  At any one time, she has several postdocs and technicians and typically 6-7 graduate students. Further, Quigg has spent over 150 days at sea in the Gulf of Mexico. Quigg has extensive experience leading and participating in multiple PI programs, including being responsible for all management aspects of the programs, writing reports and handling budgets, acting in effect as a program manager for these research programs. As the consortium director and chief scientific officer, she will lead this team towards an understanding of aggregation and degradation of dispersants and oil by microbial exopolymers (ADDOMEx). Quigg will bridge her expertise of phytoplankton ecophysiology with the chemists, biologists, engineers on the team to develop a process based understanding of this phenomenon. Quigg is currently involved in a range of projects from studying freshwater inflows and bioindicators in Galveston Bay, to mechanisms controlling hypoxia, and to lab studies on the impact of engineered nanomaterials and the potential for algal biofuels.

PhD student in Dr. Chin's lab, have both biotechnology and material science background. His has experiment on lab-on-chip design and fabrication for microfluidic application on bioreactor. Currently he works on the fabrication and design of microfluidic devices for environmental stress selection system.

I recently graduated from Texas A&M University with my bachelor’s in Biology and an Oceanography minor. I focused my undergraduate research project on phytoplankton community structure along the Texas coast using an Imaging FlowCytobot in Dr. Lisa Campbell’s lab. I joined Dr. Quigg’s lab to work on the Aggregation and Degradation of Dispersants and Oil by Microbial Exopolymers (ADDOMEx) project funded by Gulf of Mexico Research Initiative where we will be analyzing the effects of oil on phytoplankton and their production of marine snow. I am also helping with the new Imaging FlowCytobot by collecting samples and identifying phytoplankton. Prior to starting my Master’s degree, I worked as a Research Assistant for over a year on the ADDOMEx project and helped run and design the experiments. Now for my thesis, I have narrowed my focus to studying the effects of ocean acidification and oil on diatom aggregation and physiological responses.

I’m interested in the community response of phytoplankton to both anthropogenic effects and global climate change. I received my bachelor’s in Biology with a focus on Marine Biology in 2014 from the University of Texas at Austin. After graduating, I worked on a project investigating the use of phytoplankton for biofuels through Texas A&M Agrilife. Before moving to Galveston, I studied the effects of the Deepwater Horizon Oil Spill on the biogeochemistry and net primary productivity of Louisiana Salt Marshes as a research assistant in the Roberts Lab at the Louisiana Universities Marine Consortium (LUMCON). I’m currently a Master’s student in the Phytoplankton Dynamics Laboratory investigating the effects of crude oil and dispersants on the community structure and transcriptomes of both phytoplankton and microbes as part of the Aggregation and Degradation of Dispersants and Oil by Microbial Exopolymers (ADDOMEx) project.
