Programmable Excitonic Systems on DNA Nanostructures Excitons are mediators in both absorption and emission of light. Mastering the flow of excitons is the “holy grail” of light-harvesting systems, which include photovoltaic devices and microscopy probes. I am programming DNA nanostructures for control of nanoscale energy transport and investigation of new optical properties.

Bacterial Cell Wall Synthesis
Peptidoglycan synthesis plays a central role in bacterial cell growth. I am applying super-resolution fluorescence imaging in collaboration with the Garner lab to extract chemical mechanisms of cell wall growth using single-particle trajectory analysis, fluorescence fluctuation analysis, and Bayesian inference.

Excitonics of Multi-chromophore-DNA Assemblies
I am designing and analyzing DNA-based multi-chromophore assemblies for nanoscale energy transfer, light-harvesting and biosensing applications.
Phenotypic Profiling of Neuronal Synaptic Proteins
Synaptic proteins regulate a wide range of activities central to neurotransmission including homeostasis, trans-synaptic cell-adhesion, and vesicle-mediated neurotransmitter release. I am using multiplexed fluorescence imaging to characterize synaptic proteins in neuronal circuits using nucleic acid based imaging probes.

Structural DNA Nanotechnology
I am developing sequence design procedures to render arbitrary 3D nanostructures using synthetic DNA.
Cell Classification using Multiplexed Immunophenotyping
Multicellular tissue environments contain a diverse mixture of cellular classes and states, for example, the tumor microenvironment consists of genetically diverse tumor cells as well as immune cells and normal stroma. I utilize multiplexed fluorescent imaging enabled by DNA barcoding to classify cells in complex tissue environments. I then teach computer vision systems to recognize these cellular classes in common histology images, enabling detailed characterization of the tumor microenvironment and other complex tissue environments.

Phenotypic Profiling of iPSC-derived Neurons
I am designing microfluidic systems to enable multiplexed fluorescence imaging of iPSC-derived neurons to model psychiatric disease.
Structured DNA Assemblies for Vaccines and Delivery
I am using structured DNA assemblies to organize antigens, peptides, and lipids for immune cell stimulation in vaccine development and targeted cellular delivery.
Structural DNA Nanotechnology
DNA can be programmed to self-assemble into diverse nanoscale geometries. Functionality can be programmed by scaffolding secondary molecules to create systems such as multi-enzyme cascades, biological delivery vehicles, and nanoscale energy transport systems. I am using a combination of computational modeling and experiment to distill thermodynamic principles driving folding pathways and stability of these assemblies.
