Dr. Harris H. Wang's lab focuses on understanding the complex ecosystems of microorganisms in the gastrointestinal tract, emphasizing how their spatial distribution impacts health and disease. By using advanced techniques like spatial metagenomics and single-cell genomics, the lab investigates how the gut microbiome contributes to digestion, immune responses, and recovery from infections, such as Clostridioides difficile. Their innovative approaches aim to enhance our understanding of microbial roles and pave the way for better microbiome-based therapies.

Dr. Hashim Al-Hashimi's lab at Columbia University focuses on understanding how HIV-1, the virus that causes AIDS, regulates its own replication through RNA structures. By studying the dynamics of RNA and its interactions with proteins, the lab aims to create models that predict how these processes work at a molecular level. This research could lead to new strategies for developing targeted therapies that impede the virus's ability to replicate.

Dr. Alexander Sobolevsky's lab focuses on understanding the structure and function of important proteins involved in sensory signaling and neurotransmission. His research primarily targets two classes of ion channels: the TRPV3 channel, which is involved in skin sensations and several skin diseases, and ionotropic glutamate receptors (iGluRs), which are crucial for communication in the brain. By exploring how these channels work at a molecular level, the lab aims to lay the groundwork for developing better treatments for various health conditions.

Dr. Stavros Lomvardas's lab at Columbia University focuses on understanding how olfactory receptors work at the molecular level and how they influence brain connections. The team conducts research on gene expression in sensory neurons and how these processes can lead to precise brain functions. Their work has important implications for treating neurodevelopmental disorders and understanding the basic biology of the sense of smell.

The Mann lab at Columbia University studies how certain genes, known as Hox genes, control the identities of different body parts in fruit flies, which helps us understand how animals develop. They combine techniques from genetics, biochemistry, and genomics to decipher the roles of these genes at a very detailed level. Through this research, they also explore the mechanisms that could be relevant to human diseases caused by gene regulation issues, like cancer and diabetes.

Dr. Laura F Landweber's lab at Columbia University focuses on understanding how natural processes in tiny organisms called microbial eukaryotes, like Oxytricha, edit their genomes. They explore complex ways DNA and RNA are processed and rearranged, shedding light on genetic diversity and evolution. This research is important because it can reveal insights into genetic disorders and cancers seen in humans.

Dr. Thomas P. Maniatis's lab studies how specific genes help form the connections between neurons in the brain during development. They focus on a group of genes known as protocadherins, which give neurons unique identities necessary for building proper neural circuits. By investigating how mutations in these genes can affect brain wiring, the research aims to understand their role in neurodevelopmental disorders such as autism and schizophrenia. Overall, the lab seeks to uncover the underlying mechanisms that could lead to new treatments for these conditions.

Dr. Samuel K Sia's lab focuses on creating innovative diagnostic tools that are both environmentally friendly and efficient. One of their key projects involves developing biodegradable materials for microfluidic devices, which can help reduce waste in medical testing. Another major aim is to create a rapid and user-friendly test for hepatitis C that combines sample preparation and testing into one quick process, making it easier for patients to get diagnosed and treated in a single visit.

Arthur G. Palmer's lab focuses on understanding how the shapes of proteins and their movements influence their functions in biological processes. They study conformational changes in proteins—like how they fold or interact with other molecules—using advanced techniques such as NMR spectroscopy and molecular dynamics simulations. Their research has implications for various diseases and can aid in the design of new therapeutic agents.

Chaolin Zhang's research lab at Columbia University focuses on understanding how RNA molecules and their binding proteins regulate gene expression, especially in the brain. They study alternative splicing, a process that generates diverse proteins from a single gene, which is crucial for the function of different neuronal cell types. Their work aims to map regulatory elements that control this splicing and investigate how alterations in these processes can lead to neurological disorders and other diseases.
