The most widely-used mechanism to control cell volume is active ion transport. Experiments on adhered cells surprisingly revealed that their volume is significantly reduced as their basal area is increased1. We have developed a physical theory2 which considers both electrostatics and cell activity to predict a generic relation for how adhered cells regulate their volume in response to changes in their area, in agreement with the observations. Those measurements also show that the nuclear volume scales with the cell volume. Recently, the Volk group3 using intact-organism imaging, discovered that changes in nuclear volume dramatically varies the spatial organization of chromatin (DNA and associated proteins); this may have important consequences for gene expression. A simple polymeric model4 that includes the competition of chromatin self-attraction and interactions with the nuclear membrane, predicts transitions in the chromatin organization relative to the nucleus from peripheral to central to conventional, as the nuclear volume is reduced, as measured in the experiments of the Volk group. -

In my seminar, I will present our studies defining how a distinctive DNA methylation landscape is established in neurons and exploring how this methylation is read out to control critical gene expression programs. I will discuss the role of gene expression and genome architecture in shaping genomic profiles of non-CG methylation and highlight emerging mechanistic insights into how non-CG methylation and the Rett syndrome protein, MeCP2, work together to control transcription. Finally, I will outline growing evidence that disruption of this regulatory pathway contributes to neurodevelopmental disorders.

Thermosensitive microgels are widely studied hybrid systems combining properties of polymers and colloidal particles uniquely. This study explores the frequency-dependent linear viscoelastic properties of dense suspensions of micron-sized microgels in conjunction with an analysis of the local particle structure and morphology-based on superresolution microscopy. By identifying the dominating mechanisms that control the elastic and dissipative response, we can explain these widely studied soft particle assemblies' rheology. Interestingly, our results suggest that the polymer brush-like corona's lubrification reduces friction between the microgel contacts. -

This has been recently extended with the rather complete understanding of topological states of noninteracting electrons. In this talk I will focus instead on new physics that arises from the interplay of topology and strong interactions. A unifying theme will be the emergence of gauge fields rather than the classical order parameters of Landau theory. I will illustrate these general themes with two recent works. The first proposes a route to realizing a long sought after phase - the Z2 quantum spin liquid - in a synthetic platform, an array of highly excited (Rydberg) atoms [1]. A potential application to the engineering of naturally fault tolerant quantum bits will also be described. The second example describes a topological route to strong coupling superconductivity [2], which was inspired by recent experimental observations in magic angle bilayer graphene and related devices.

To accelerate native MS studies, the Sharon lab developed the direct-MS method for analysis of proteins directly from crude lysates. I will discuss a general overview of the many applications enabled by direct-MS, with a particular focus on my work extending the technique to eukaryotic expression systems. By analyzing proteins directly from eukaryotic cell lysates, we can observe changes in ligand binding due to addition of cofactors or drugs to the media. We anticipate that this method will be broadly applicable to studies of eukaryotic post-translational modifications and protein stability as well as drug uptake and target engagement in eukaryotic cells.
