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. 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.
Graduate Students

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.

Trevor Grandy
B.S. Environmental Science, Alma College
M.S Candidate
See Biography
Trevor graduated from Alma College located in Alma, Michigan with a Bachelor of Science in Environmental Science. During this time, he participated in 3 years of undergraduate research investigating the impacts of road salts on aquatic plants and invertebrates. He is very excited to be investigating pesticide concentrations in Chinook salmon while in the Lydy lab at Southern Illinois University. Outside of work, Trevor enjoys fishing and watching movies.

Erin Melcher
B.S. Biology and chemistry minor, Slippery Rock University
M.S Candidate
See Biography
Erin recently graduated from Slippery Rock University with a B.S in Biology and minor in Chemistry, along with a B.A in Spanish. She has previous research experience with earthworm ecology, critical thermal maxima in Atlantic crabs, and behavioral spectrums in Adirondack brook trout. In the Lydy lab, Erin will be working with pesticide uptake in Chinook salmon. Outside of her research, she enjoys hiking, traveling, baking, and learning different languages.
Undergraduates

Juan Valencia-Tun
Zoology Major
See Biography
Juan Valencia-Tun is a junior at SIUC majoring in Zoology and minoring in English. His area of interest is the use of captive breeding as a means of conservation of species that are in danger of being, or already are, extinct in the wild. He is also interested in scientific divulgation with respect to educating the public on the importance of conservation, especially concerning “unwanted” or “unpopular” species, such as reptiles and invertebrates. In his free time he enjoys hiking, fishing, cooking, and herpetoculture.
