Furthermore, a number of labs are dedicated to protein biochemistry and structural biology. They are working to understand how proteins fold into their precise three-dimensional structures and how misfolding can lead to diseases like Alzheimer’s, Parkinson’s, and cystic fibrosis. Using techniques such as X-ray crystallography, cryo-electron microscopy (cryo-EM), and nuclear magnetic resonance (NMR) spectroscopy, these scientists are generating atomic-level insights that are critical for rational drug design and therapeutic intervention. The interplay between fundamental cell biology and disease mechanisms is a recurring theme, driving the pursuit of knowledge that can directly impact human health.
2. Neuroscience and Behavior: Unraveling the Brain’s Enigmas
The human brain, with its billions of neurons and trillions of connections, remains one of biology’s most profound mysteries. Emory’s Neuroscience and Behavior labs are at the forefront of deciphering its complexities, investigating everything from the molecular mechanisms of synaptic plasticity to the neural circuits underlying complex behaviors and cognitive functions.
Research in this area often spans multiple levels of analysis. At the molecular and cellular level, scientists are exploring the development and function of neurons and glia, the non-neuronal cells critical for brain health. This includes studies on how neurons form connections (synapses) during development, how these connections are strengthened or weakened over time (synaptic plasticity), and how these processes contribute to learning and memory. Labs are also deeply invested in understanding the pathogenesis of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and ALS, identifying molecular targets and potential therapeutic strategies.
Beyond the cellular realm, researchers are investigating the neural bases of behavior. This involves using advanced imaging techniques (like fMRI and two-photon microscopy), electrophysiology, and optogenetics to map neural circuits involved in sensory processing (e.g., vision, olfaction), decision-making, social interactions, and emotional regulation. For example, some labs are studying the neural mechanisms underlying stress and anxiety disorders, while others explore the genetic and environmental factors that shape social behavior, often utilizing model organisms to gain insights into conserved neural pathways. The ultimate goal is to translate these fundamental discoveries into new treatments for neurological and psychiatric disorders.
3. Ecology and Evolutionary Biology: Understanding Life’s Interconnectedness
Emory’s Ecology and Evolutionary Biology (EEB) labs explore life on a grander scale, investigating how organisms interact with each other and their environment, and how these interactions drive evolutionary change over time. This research is crucial for understanding biodiversity, predicting the impacts of climate change, and developing effective conservation strategies.
One major focus is disease ecology, studying how pathogens spread through populations and across species, and how environmental changes influence disease dynamics. Researchers might investigate the ecology of vector-borne diseases like malaria or Lyme disease, or the spillover events of zoonotic diseases from wildlife to humans. This work often involves fieldwork, epidemiological modeling, and genetic analysis of pathogens and hosts.
Another key area is evolutionary genetics and genomics. Labs are using genomic data to reconstruct the evolutionary history of species, identify genes responsible for adaptation to new environments, and understand the genetic basis of complex traits. This includes studies on how populations adapt to climate change, how speciation events occur, and the evolutionary arms race between hosts and parasites. Researchers might analyze large datasets of DNA sequences from diverse organisms to uncover patterns of natural selection and genetic drift.
Furthermore, EEB labs are deeply involved in conservation biology and ecosystem dynamics. This research assesses the impact of human activities on natural ecosystems, evaluates biodiversity loss, and develops strategies for protecting endangered species and restoring degraded habitats.
