Professor of Materials Science and Engineering
On Leave from 10/01/2020 To 12/31/2020BioThe Melosh group explores how to apply new methods from the semiconductor and self-assembly fields to important problems in biology, materials, and energy. We think about how to rationally design engineered interfaces to enhance communication with biological cells and tissues, or to improve energy conversion and materials synthesis. In particular, we are interested in seamlessly integrating inorganic structures together with biology for improved cell transfection and therapies, and designing new materials, often using diamondoid molecules as building blocks.
My group is very interested in how to design new inorganic structures that will seamless integrate with biological systems to address problems that are not feasible by other means. This involves both fundamental work such as to deeply understand how lipid membranes interact with inorganic surfaces, electrokinetic phenomena in biologically relevant solutions, and applying this knowledge into new device designs. Examples of this include “nanostraw” drug delivery platforms for direct delivery or extraction of material through the cell wall using a biomimetic gap-junction made using nanoscale semiconductor processing techniques. We also engineer materials and structures for neural interfaces and electronics pertinent to highly parallel data acquisition and recording. For instance, we have created inorganic electrodes that mimic the hydrophobic banding of natural transmembrane proteins, allowing them to ‘fuse’ into the cell wall, providing a tight electrical junction for solid-state patch clamping. In addition to significant efforts at engineering surfaces at the molecular level, we also work on ‘bridge’ projects that span between engineering and biological/clinical needs. My long history with nano- and microfabrication techniques and their interactions with biological constructs provide the skills necessary to fabricate and analyze new bio-electronic systems.

Timothy Meyer
Stanford University Professor of Nephrology
Current Research and Scholarly InterestsInadequate removal of uremic solutes contributes to widespread illness in the more than 500,000 Americans maintained on dialysis. But we know remarkably little about these solutes. Dr. Meyer's research efforts are focused on identifying which uremic solutes are toxic, how these solutes are made, and how their production could be decreased or their removal could be increased. We should be able to improve treatment if we knew more about what we are trying to remove.

Daria Mochly-Rosen
The George D. Smith Professor in Translational Medicine
Current Research and Scholarly InterestsTwo areas: 1. Using rationally-designed peptide inhibitors to study protein-protein interactions in cell signaling. Focus: protein kinase C in heart and large GTPases regulating mitochondrial dynamics in neurodegdenration. 2. Using small molecules (identified in a high throughput screens and synthetic chemistry) as activators and inhibitors of aldehyde dehydrogenases, a family of detoxifying enzymes, and glucose-6-phoshate dehydrogenase, in normal cells and in models of human diseases.

W. E. Moerner
Harry S. Mosher Professor and Professor, by courtesy, of Applied Physics
Current Research and Scholarly InterestsLaser spectroscopy and microscopy of single molecules to probe biological systems, one biomolecule at a time. Primary thrusts: fluorescence microscopy far beyond the optical diffraction limit (PALM/STORM/STED), methods for 3D optical microscopy in cells, and trapping of single biomolecules in solution for extended study. We explore protein localization patterns in bacteria, structures of amyloid aggregates in cells, signaling proteins in the primary cilium, and dynamics of DNA and RNA.

Denise M. Monack
Professor of Microbiology and Immunology
Current Research and Scholarly InterestsThe primary focus of my research is to understand the genetic and molecular mechanisms of intracellular bacterial pathogenesis. We use several model systems to study complex host-pathogen interactions in the gut and in immune cells such as macrophages and dendritic cells. Ultimately we would like to understand how Salmonella persists within certain hosts for years in the face of a robust immune response.
