Dr. S.D.M Chinthaka Sinhapura
Ph.D Analytical Chemistry, Wayne State University
Post-doctoral Researcher
See Biography
Chinthaka Sinhapura is currently involved in determining pesticide residues and lipid levels in archived fish and fish from sublethal exposure experiments. The pesticide determination is carried out using a modified QuEChERS method, and lipid determination is carried out by the Vanillin phosphoric acid method. His main professional goal is to explore new knowledge and developments in analytical and environmental chemistry. I aim to acquire operational skills in state-of-the-art analytical instrumentation. Outside of professional work, Chinthaka enjoys cycling and gardening, especially growing vegetables and fruits.
Dr. Giovanni Molinari
Ph.D Zoology, Southern Illinois University
Post-doctoral Researcher
See Biography
Giovanni Molinari is currently focusing on the bioavailability, bioaccumulation, and subsequent effects of pesticides in aquatic ecosystems. His primary research goal is to develop response spectrum models for the effects of pesticides on Chinook Salmon, and to assess pesticide residues in Wakasagi collected from the Sacramento Deep Water Ship Channel. His previous research focused on fish nutrition and improving the sustainability of aquaculture through reduced fishmeal use and more efficient feeding strategies for larval fish. Outside of work, Giovanni coaches soccer for a nearby high school, and he also likes to fish, hike, and play video games with friends.
Dr. Hadis Miraly
Ph.D Environmental Biology, SUNY College of the Environment and Forestry
Post-doctoral Researcher
See Biography
Hadis Miraly is currently focusing on the bioaccumulation and biotransformation of pesticides in aquatic ecosystems. Their primary research goal is to develop response spectrum models for the effects of pesticides on Chinook Salmon. Hadis’s professional interests include the study of pesticide impacts on aquatic life and the development of models to predict these effects. Their previous research explored the influence of climate-driven deoxygenation on the bioaccumulation of mercury in fish, showcasing a commitment to understanding how environmental stressors affect aquatic ecosystems. In their free time, Hadis enjoys reading poetry, listening to podcasts, and engaging in yoga and hiking. These activities offer a balance to their scientific pursuits and contribute to their overall well-being.

Cristina La
B.S Environmental Science, Western Washington University
M.S Candidate
See Biography
Throughout Cristina’s time here at SIU, they have worked on multiple projects with the overall goal of looking at contaminant partitioning throughout the Sacramento Deep Water Ship Channel to get an understanding of the potential risk of contaminant exposure to aquatic biota and how different resuspension events may impact bioavailability. Cristina’s research interests center around the fate and transport of chemicals in aquatic environments, biomonitoring, and environmental justice. When not binging shows, they love going on bike rides and walks around the campus, cooking egregious amounts of food, and playing games with their fellow lab mates.
Braden Weaver
B.S Chemistry, University of Wyoming
M.S Candidate
See Biography
Braden Weaver is currently working on method development for the detection of neonicotinoid pesticides in chickens. These compounds can enter nontarget animals through various routes of uptake and may cause unintentional adverse health effects within the organism. Braden recently graduated from the University of Wyoming with a B.S in Chemistry and moved to Carbondale where both him and his spouse are enrolled in a graduate program.
