Research Summary
Microbial genomes encode the largest molecular, biochemical, and functional diversity on Earth. We focus on developing machine learning models and experimental approaches to discover and design novel biological functions. We integrate computation with expertise in evolution, ecology, and biochemistry to characterize and harness the functional potential of microbes.

Research Summary
Sergey Ovchinnikov uses phylogenetic inference, protein structure prediction/determination, protein design, deep learning, energy-based models, and differentiable programming to tackle evolutionary questions at environmental, organismal, genomic, structural, and molecular scales, with the aim of developing a unified model of protein evolution.

Research Summary
Different cells take on an astonishing variety of shapes, which are often critical to be able to perform specialized cell functions like absorbing nutrients or contracting muscles. We study how different cell shapes arise and how cells control the spatial distribution of their internal constituents. We take advantage of the tractability of fungal model systems, and address these questions using approaches from cell biology, genetics, and computational biology to understand molecular mechanisms.

Research Summary
We use the tiny, transparent jellyfish, Clytia hemisphaerica, to ask questions at the interface of nervous system evolution, development, regeneration, and function. Our foundation is in systems neuroscience, where we use genetic and optical techniques to examine how behavior arises from the activity of networks of neurons. Building from this work, we investigate how the Clytia nervous system is so robust, both to the constant integration of newborn neurons and following large-scale injury. Lastly, we use Clytia’s evolutionary position to study principles of nervous system evolution and make inferences about the ultimate origins of nervous systems.

Research Summary
Our bodies are tuned to detect and respond to cues from the outside world and from within through exquisite collaborations between cells. For example, the cells lining our airways communicate with sensory neurons in response to chemical and mechanical signals, and evoke key reflexes such as coughing. This cellular collaboration protects our airways from damage and stabilizes breathing, but can become dysregulated in disease. Despite their vital importance to human health, fundamental questions about how sensory transduction is accomplished at these sites remain unsolved. We use the mammalian airways as a model system to investigate how physiological insults are detected, encoded, and addressed at essential barrier tissues — with the ultimate goal of providing new ways to treat autonomic dysfunction.

Research Summary
We study how cells regulate the spatial organization of signaling molecules at the plasma membrane to control downstream signaling. For example, receptor clustering and higher-order assembly with cytoplasmic proteins can create compartments with unique biochemical and biophysical properties. We use quantitative experimental approaches from biochemistry, molecular biophysics, and cell biology to study transmembrane signaling pathways and how they are misregulated in diseases like cancer.

Research Summary
We study the interplay of gene expression and genome organization. Our work focuses on understanding how large molecular machineries involved in genome organization and gene transcription regulate each others’ function to ultimately determine cell fate and identity. We employ a broad range of approaches including single-particle cryo-electron microscopy (cryo-EM), X-ray crystallography, biochemistry, and genetics to mechanistically understand how these molecular assemblies regulate each other across molecular scales.

Research Summary
The Kaiser lab studied protein folding and intracellular trafficking in the yeast S. cerevisiae. Their work focused on the protein folding in the endoplasmic reticulum (ER), quality control mechanisms in the ER, and membrane protein sorting in Golgi compartments. They combined genetic, biochemical, and cell biological methods to gain an understanding of the molecular mechanisms underlying each of these processes. Chris Kaiser is no longer accepting students.
