Archana Venkatachari

Archana obtained her B.Sc. with a triple major in Chemistry, Environmental Science and Zoology from Bangalore University, India. She went on to study Ocean Studies and Marine Biology in Andaman and Nicobar Islands and graduated in 2020 from Pondicherry University, India. In her master’s she studied the diel vertical migration of zooplankton in the South Andaman sea. She will be starting her doctoral studies under Dr. Bourbonnais in spring 2021. She will be analyzing nutrients and stable isotopes of nitrogen species for a project using computational methods and big data science to better predict harmful algal blooms in Lake Wateree and lake Murray in South Carolina. She is very thrilled to work on this project and is electrified to work in the Bourbonnais lab. 

Birch Maxwell Lazo-Murphy

Birch graduated from Syracuse University with a B.S. in Environmental Engineering in May of 2021. During his time at Syracuse, he worked for three years in Dr. Charles T. Driscoll’s biogeochemistry laboratory researching long term Hg and MeHg trends in a remote Adirondack watershed. In the latter half of his tenure, he began to analyze the relationship between Hg species, DOC, and fractional components of DOM. He has partaken in sampling trips and has presented his research at the annual New York Water Environment Association conference. He will bring both analytical and collaborative expertise to the University of South Carolina in the Fall of 2021 where he will work jointly in the Bourbonnais and Peng laboratories. He will be pursuing a PhD in Marine Science.

Darcy Perin

Darcy is an undergraduate student at the University of South Carolina, pursing a B.Sc. in Marine Science with a minor in geography. She plans to apply to a graduate school in 2021, where she hopes to study chemical or biological oceanography.

Over the summer after her freshman year, Maggie worked as a research assistant on multiple projects in the University of Tennessee’s Water Resources Engineering program. Maggie plans on continuing to work in research throughout undergrad, then attending graduate school for microbiology and pursuing a research career in environmental microbiology. She is very excited to be working with the Bourbonnais lab!

Elise Lumsden

Elise is an undergraduate student at the University of South Carolina, pursuing a B.Sc in Marine Science with a minor in public health. She plans to graduate in 2023 and hopes to pursue an accelerated master’s degree in physical or chemical oceanography. She will concentrate her profession towards the issue of climate change as this is something she is passionate about. Elise is currently interning in a research lab, under Dr. Bourbonnais. Through her internship, she has been introduced to different chemical methods used to analyze the nutrient concentrations and the nitrogen isotopic composition of nitrogen species sampled from the Western Arctic. In her free time, she enjoys working out, volunteering, snowboarding, and spending time with friends and family. She is very excited to be exposed to research early on and cannot wait for the professional and academic opportunities that lie ahead.

Lab Alumni
Holly Westbrook

Holly graduated from University of Connecticut with a B.S. in Marine Science with a minor in Chemistry in May of 2017. After graduation, she began working in Dr. Julie Granger's lab as a research technician where she researched the δ  O to δ  N relationship during nitrate consumption in different aquatic environments, and maintained in situ equipment in a local cove, and assisted in sampling trips in the Pawcatuck River over the summer of 2017. She also participated in the  GO-SHIP line IO7N cruise, running closed cell alkalinity titrations and collecting samples for University of Miami RSMAS. During her undergraduate studies she participated in a SEA Semester, which was a transatlantic crossing focusing on climate change and the global carbon cycle, as well as an independent study about organic alkalinity in wetlands. Under Dr. Bourbonnais, her research will focus on nitrous oxide in the water column and sediment in the Arctic.



Jaquan High

Jaquan is an undergraduate student at the University of South Carolina, currently pursuing a B.S. in Geology with a concentration in Environmental Science. After graduating in 2021, he plans to pursue a PhD in Ocean Ecology and Biogeochemistry. In the summer of 2021, Jaquan completed a 10-week research internship with NOAA and the Padilla Bay NERR testing a new method of snail sampling and studying animal-sediment interacts that occur in Padilla Bay, WA. His work with Dr. Bourbonnais will be a continuum of this research, while also gaining an invaluable experience working with particular lab equipment and learning how to navigate through academia.

Adriana Webb

Adriana is a current undergraduate senior at the University of South Carolina, pursuing a B.S. in Marine Science with emphasis on chemical and biological oceanography. She is currently applying to graduate schools to obtain a M.S. in marine science and possibly a Ph.D., where she is looking to study phytoplankton, their influence on chemistry as well as ecological roles in the marine environment. She is currently working in the Bourbonnais lab, as well as the lab of Professor Jay Pinckney, to provide any needed assistance and to learn more about freshwater phytoplankton in local lakes, using her previous lab and field work experience from classes at UofSC. Adriana is excited to be working with both professors and looks forward to Spring 2021, where she will continue to learn more about freshwater phytoplankton blooms and conduct her own research comparing freshwater and saltwater phytoplankton from the North-Inlet estuary.
