Pavani Ganju

Pavani Ganju

Laboratory Manager

While Pavani grew up in small-town India, she completed her bachelor's degree in Plant Sciences at the University of California, Davis. After completing her master's degree in Botany at the University of Wisconsin, Madison, where she investigated clay mineral interactions at the micro-scale, she joins the agroecology laboratory as our lab manager. She is very excited to be contributing to the lab's many research projects, and in making sure the lab is running smoothly and efficiently. When she's not in lab, she can be found reading science fiction novels and completing crossword puzzles in her free time.

Carson Pearl

Carson Pearl

Research Specialist

Carson is from St. Louis, Missouri and graduated with a BS in Plant Sciences from the University of Missouri, and most recently, an MS in Agronomy (2025) from the Purdue Agroecology Lab. He will continue to use his background in plant science as a research specialist to ask questions about how plant-soil interactions effect soil carbon building. Carson is a Purdue sports fan and even made the trek to West Lafayette from Missouri almost every home football weekend growing up. Carson is proud to be the next boilermaker in his family and is happy to continue working in PAL.

Binod Joshi

Binod Joshi

PhD Student

Binod is originally from Nepal and he obtained his master’s degree in integrated Agricultural Science from Texas State University in 2023. At Purdue, he aspires to enhance knowledge and skills in soil and crop science and will focus on assessing the holistic approach for fertility sources in corn production systems, utilizing the concepts of nutrient management strategies, microbial communities, soil health indicators, and socio-environmental impacts. He hopes to gain valuable insights into sustainable soil fertility management practices. Outside of academics, he loves to watch movies, travel, and play cricket.

Annie Benson

Annie Benson

MS Student

Annie grew up in central Minnesota where her family raised vegetables, chickens, and sheep. After graduating from Middlebury College with a degree in biology, she worked at Rodale Institute in Pennsylvania for several years as a research technician on a long term trial comparing organic and conventional grain cropping systems. She is ecstatic to have joined the agroecology lab on the Indiana Organic Network (ION) project team, where she will help conduct a statewide soil health assessment of organic farms and investigate how management practices influence soil health dynamics. In her free time, Annie enjoys rock climbing, baking, and tormenting her two cats.

Sheng Lu

Dr. Sheng Lu

Post-doctoral Researcher

Sheng is currently a post-doctoral researcher in our lab. His primary research focuses on the dynamic interactions between soil microbial communities and metabolite composition, with an emphasis on nutrient cycling. At Purdue, he’s investigating how these processes interact under different crop rotation systems. Sheng earned his doctorate from Hunan Agricultural University and then worked at Central South University of Forestry and Technology as an Associate Professor. Outside of his research, Sheng enjoys driving to new and exciting locations to take in the sights and enjoy nature.

Yang Chen

Yang Chen

PhD student
Yang is a PhD student in our lab. He completed his master’s degree at the University of Chinese Academy of Sciences. His prior work integrated meta-analysis with pot control experiments to examine how soil microbial communities and extracellular enzyme activities in the rhizosphere and bulk soil react to nitrogen addition. At Purdue, his research will concentrate on soil microbial regulation of organic matter dynamics and the influence of management practices, particularly focusing on perennial legumes.

Arsen enjoys connecting with people and exploring different cultures through travel. Deeply connected to his Kazakh heritage, he plays the Dombra, a traditional instrument, and is passionate about agriculture, driven by a desire to reconnect people with Kazakhstan's vast land resources. In his free time, Arsen enjoys outdoor activities, cooking, and spending time with friends and family. His varied experiences and interests make him eager to grow and collaborate with others in both his academic and personal life.

Dominic Uhelski

Dr. Dominic Uhelski

Visiting Scholar

Dominic is a visiting scholar in the lab. He is currently working as a postdoctoral researcher at Michigan Technological University, where he focuses on wetland restoration and biogeochemistry. His past research includes quantifying fire history and analyzing peat chemistry in the Northern Midwest, as well as studying pyrogenic carbon variance affected by forest fires in Northern Wisconsin. He has a broad interest in ecological stewardship and sustainability.

Panchami Jaya

Panchami Jaya

Visiting PhD Student

Panchami is a visiting Ph.D. student from the Kerala Forest Research Institute (Forest Research Institute Dehradun-University) in India. Her research focuses on the vertical distribution of soil carbon pools, mineral-organic interactions, and the impact of rising global temperatures on soil organic carbon in teak plantations and adjacent forests of the southern Western Ghats. At Purdue University, Panchami's work extends to studying how regenerative agroforestry systems affect soil microbial parameters compared to conventional agriculture, contributing to carbon sequestration and climate change mitigation. Beyond her academic pursuits, she enjoys reading and traveling, which continually inspire her commitment to developing innovative solutions for a sustainable climate future.

Ismael De lara

Ismael De lara

Undergraduate Student

Hello! I'm Ismael De lara, I’m a senior in Natural Resources with Environmental Science with a concentration in Environmental Quality and Restoration. I’m from Knox, Indiana. I came to Purdue through the Pathway to Purdue Program. On campus, I’m the Environmental Science Club president, an ambassador for the Natural Resources and Environmental Science Program, and I do research for the Purdue Agroecology Lab by helping with the ION project and a project on carbon sequestration policy integration into organic agriculture. In my free time, I’m working on a children’s book about community environmental advocacy, baking, and raising my two sheep in NW IN. I hope to go to graduate school to get my MS in Agronomy and influence agriculture policy.
