Dr. Kimberly Komatsu (she/her) - lead investigator

Dr. Komatsu is an ecologist who investigates how community dynamics are being altered by human-caused global change in ecosystems around the world, including grasslands, forests, and agro-ecosystems. Her research focuses on plant competitive dynamics, plant-herbivore interactions, and the legume-rhizobia mutualism. She utilizes long-term experiments, observational data collection, and broad scale data synthesis to uncover the consequences of climate change, nutrient pollution, and biodiversity loss.               CV​               Google Scholar               email    
Rachael Brenneman (she/her) - PhD student

Rachael is a PhD student interested in studying global change in grasslands, especially as it pertains to rangeland management and conservation. Understanding how our grasslands are changing is vital to finding the balance between conservation and proper management for grazing.               ​email

Elise Grabda (she/her) - PhD student

Elise's research interests are focused on understanding the impacts of climate change and anthropogenic stressors on community assemblages, ecosystem functioning, and the mechanisms which enhance resilience to those stressors. Specifically, how ecosystem functions in grasslands are enhanced by biodiversity across trophic levels and through time.               ​​email

Kelly Clark (she/her) - PhD student

Kelly's research interests include investigating plant soil-microbe interactions and how they influence community dynamics in various ecosystems. Currently, she is interested in legume/rhizobia relationships and how rhizobia can influence invasions.           CV               ​email

Kai DeLeon (he/him) - MS student

Kai is a master’s student who is interested in connecting biogeochemical cycles to population dynamics through the lens of the decomposer community. He is currently studying how decomposition drives nutrient cycling in the nutrient limited longleaf pine savanna.                             CV                                  email


Maya Parker-Smith (she/her) - lab manager

Maya is interested in the ecological drivers of change in tallgrass prairies. She completed her master's degree at the University of Missouri in 2022 where she studied how seed predation can affect restorative efforts in prairies. She hopes to delve further into how ecosystem management can mediate anthropogenic impacts in grasslands.               email


Jonathan Bean (he/him) - undergraduate researcher

Hey everyone, my name is Jonathan Bean. I am an undergraduate here at UNCG studying biology with a minor in chemistry. I am excited to get some hands-on experience learning lab techniques and to further my knowledge on the impacts of climate change. My lab interests lean more towards the realm of pathology and disease ecology, and I hope my time with the Community Dynamics Lab will strengthen my knowledge of the impacts climate change has on disease.

Miles Bellion (he/him) - undergraduate researcher

Hello! My name is Miles Bellion, I am an undergraduate Biology major, Chemistry minor here at UNCG with a concentration in Environmental Biology. I’m excited to learn more lab techniques and to continue my research which looks into how nitrogen based microplastics impact plant growth and germination.

Silver Caldera (she/her) - undergraduate researcher

My research interests are based around genetics. Understanding how the DNA and genes of bacteria can not only help themselves survive but also increase the survivability of other organisms.​
 

  
     
Amia Cox (she/her) - undergraduate researcher

Hi, I am Amia! I am a junior pursuing a Biology degree with an environmental concentration! I haven't yet found my specific area of research; but, a few areas I find most intriguing surround wildlife, ecology, and biodiversity. I’m interested in how different organisms work together and rely on each other to contribute to the many phenomena that go unnoticed on our Earth. I am also interested in natural remedies, primarily provided by plants, and how they can benefits organisms in the wild and us!     
Micah Monroe (he/him) - undergraduate researcher

Hello! I’m Micah. I am a senior biology major with a chemistry minor at UNCG, currently on the pre-med track. As an aspiring physician, I am very interested in the intersection between genetics and ecology and how they relate to medicine. Outside of the lab, you can usually find me in the EUC with friends, listening to music, or on a nature walk.

​
Airelle Newkirk (she/her) - undergraduate researcher

Hi, my name is Airelle Newkirk and I am currently a junior at UNCG I am majoring in Biology and have an interest in medicine, I hope to attend Physician Assistant school after undergrad. I'm grateful for the opportunity to be involved in undergraduate research, so far it has been a fun experience.

​
Madeline Wild (she/her) - undergraduate researcher

My name is Madeline Wild and I am a junior! I'm majoring in biology and am on the pre-med track. I joined the Community Dynamics Lab to further my knowledge about the environment and to also learn good lab techniques and practices that I can use for years to come. I have really enjoyed this opportunity so far and can not wait to learn more!
