The Curtis lab is primarily focused on the physics of cell-cell and cell-extracellular matrix interactions, in particular within the context of glycobiology and immunobiology. Our newest projects focus on questions of collective and single cell migration in vitro and in vivo; immunophage therapy "an immunoengineering approach - that uses combined defense of immune cells plus viruses (phage) to overcome bacterial infections"; and the study of the molecular biophysics and biomaterials applications of the incredible enzyme, hyaluronan synthase. A few common scientific themes emerge frequently in our projects: biophysics at interfaces, the use of quantitative modeling, collective interactions of cells and/or molecules, cell mechanics, cell motility and adhesion, and in many cases, the role of bulky sugars in facilitating cell integration and rearrangements in tissues.

acoskun7@gatech.edu

Ahmet Coskun is a systems biotechnologist and bioengineer, working at the nexus of multiplex imaging and quantitative cell biology.

Single Cell Biotechnology Lab is strategically positioned for imaging one cell at a time for spatial context. We are multi-disciplinary researchers interested in photons, ions, and electrons and their interactions with cells and tissues.  Using large-scale experiments and computational analysis, we address fundamental challenges in cancers, immunology, and pediatric diseases. Variability of single cell profiles can be used to understand differences in therapeutic response, as well as satisfy our curiosity on understanding how cells are spatially organized in nature.

Our lab aims to deliver biotechnologies for spatial multi-omics profiling vision at the single cell level.

1) Spatial genomics: Our lab was part of an early efforts to demonstrate spatially resolved RNA profiling in single cells using a sequential FISH method. We will continue leveraging seqFISH and correlation FISH (another computational RNA imaging method) for exploring spatial dynamics of cellular societies.

2) Spatial proteomics: Our lab develops expertise on antibody-oligonucleotide based barcoding for multiplex protein imaging using CODEX technology. We combine CODEX with super-resolution and 3D imaging to visualize and quantify subcellular epigenetic states of immune and cancer cells.

3) Spatial metabolomics: Our lab works on computational and isotope barcoding approaches for small molecule profiling using MIBI (Multiplexed ion beam imaging). 3D and subcellular metabolic state of individual cells are used to model functional modes of cellular decision making in health and disease.

We also develop machine learning and deep learning algorithms to make sense of imaging based single cell big data.

In a nutshell, we create image-based ‘omic technologies to reveal spatial nature of biological systems. We benefit from enabler tools:  Super-resolution bioimaging, barcoded biochemical reagents, advanced algorithms and automated microfludics. Topical interests include Spatial Biology, Liquid Biopsy, and Global Oncology.

Ahmet Coskun trained at Stanford (Postdoc/Instructor with Garry Nolan), Caltech (Postdoc with Long Cai) and UCLA (PhD with Aydogan Ozcan). His lab is currently funded by NIH K25, BWF CASI, Georgia Tech & Emory.

My research interests center on control of movement by sensorimotor integration in the mammalian spinal cord. Using predominantly electrophysiological methods applied in vivo, we study neural signaling by spinal motoneurons, somatosensory neurons, and their central synapses. Our primary analyses include electrical properties, synaptic function, and firing behavior of single neurons. We are actively examining how these neurons and synapses respond soon and long after peripheral nerve injury and regeneration. Our recent findings demonstrate that successful regeneration of damaged sensory axons does not prevent complex reorganization of their synaptic connections made within the spinal cord. In separate studies, we are examining novel mechanisms of sensory encoding and their impairment which recently discovered in rodents treated with anti-cancer drugs. Both nerve regeneration and chemotherapy projects are driven by the long-term goal of accurately identifying the neural mechanisms behind movement disorders. We also continue to explore fundamental operations of the normal adult nervous system. Our most recent studies focus on synaptic modulation of motoneuron firing and on interspecies comparisons of spinal circuits.

Professor Cicerone works on development and application of spectroscopic coherent Raman imaging approaches and on dynamics of amorphous condensed matter. In the coherent Raman imaging work, his group introduced broadband (spectroscopic) coherent anti-Stokes Raman scattering (BCARS) microscopy in 2004. Since then he and his group have remained at the forefront of this field, introducing improvements such as a time-domain Kramers-Kronig transform to deal with non-causal signals for retrieving the pure Raman spectrum directly from the raw BCARS signal. The results of that work and other instrument design innovations utilizing impulsive vibrational coherence generation resulted in recognition as one of the top 10 innovations in BioPhotonics for 2014. His group has logged many imaging firsts, including the first to obtain quantitative vibrational fingerprint spectra from mammalian cells using coherent Raman imaging, and the first to identify specific structural proteins from coherent Raman imaging.His work on dynamics of amorphous condensed matter focuses on the impact of picosecond timescale spatial and temporal heterogeneity in dynamics on transport and relaxation in liquids and glasses. In 2004, he used neutron scattering to show for the first time that chemical and physical stability of proteins encapsulated in glassy sugars could be predicted by the profile of ps-timescale dynamics. Since then, he has developed a framework for calculating transport and relaxation properties of liquids and glasses over 12 orders of magnitude in time, based solely on ps-timescale dynamics, and identified the molecular origin of a relaxation process (Johari-Goldstein process) that had been observed but remained enigmatic for 50 years. He has also developed benchtop approaches accessible to pharmaceutical labs for measuring the relevant dynamics, and developed a protein stability approach for drug delivery that encapsulates proteins in nanometer-sized droplets of vitrified sugar-based glass and makes them impervious to traditional processing steps, allowing retention of ~99% of protein function or titer after all processing steps. This approach has now been used successfully in large animal trials, and has also been shown to be effective for transdermal drug delivery due to the nanometer size of the encapsulation materials.

"Craniofacial muscles are essential muscles for normal daily life. They are involved in facial expressions (facial muscles), blinking and eye movement (eye muscles), as well as speaking and eating (tongue and pharyngeal muscles). Interestingly, craniofacial muscles have differential susceptibility to several muscular dystrophies. For example, craniofacial muscles are the most affected muscles in oculopharyngeal muscular dystrophy but the least affected muscles in Duchenne muscular dystrophy. Among craniofacial muscles, dysfunction of tongue and pharyngeal muscles could cause an eating disability, called dysphagia, afflicts almost 15 million Americans including elderly, neuronal (Parkinson's disease and bulbar-onset amyotrophic lateral sclerosis) and muscular disease (oculopharyngeal muscular dystrophy) patients. However, no cure or therapeutic treatment exists for dysphagia caused by muscular dystrophy. Elucidation of the mechanism(s) behind these differing susceptibilities of craniofacial muscles could lead to development of potential therapeutics targeted to specific skeletal muscles involved in particular types of muscular dystrophy. The mechanisms of skeletal muscles are of interest here because skeletal muscle cells are multinucleated cells. Typically, skeletal muscle cells contain hundreds of nuclei in a single cell since they are generated by fusion of muscle precursor cells during development or by fusion of muscle specific stem cells, called satellite cells, in adult skeletal muscles. However, it is unclear how skeletal muscle cells regulate the quantity and quality of these multi-nuclei. Since craniofacial skeletal muscles, such as extraocular and pharyngeal muscles, have active satellite cell fusion in comparison to limb muscles, they are therefore suitable models to study myonuclear addition and homeostasis."

Yeast genetics and molecular biology, chaperones and protein misfolding, amyloid and prion diseases, epigenetics and protein-based inheritance. Mylaboratory employsyeast models to studyprionsandamyloids.Prionswere initially identified as proteins in an unusual conformation that cause infectiousneurodegenerativediseases, such as "mad cow" disease,kuruorCreutzfeldt-Jakobdisease. Infection depends on theprion'sability to convert anon-prionprotein, encoded by the same host maintenance gene, into theprionconformation.Prionsform ordered cross-beta fibrous aggregates, termed amyloids. A variety of human diseases, includingAlzheimer'sdisease, are associated with amyloids and possess at least someprionproperties. Someamyloidshave positive biological functions. Manyproteins can formamyloidsin specific conditions. It is thought thatamyloidrepresents one of the ancient types of the protein fold. Some yeastnon-Mendelianheritable elements are based on aprionmechanism. This shows that heritable information can be coded in protein structures, in addition to information coded in DNA sequence. Therefore,prionsprovide a basis for the protein-based inheritance in yeast (and possibly in other organisms). Major topics of research in my lab include cellular control of prion formation and propagation (with a specific emphasis on the role of chaperone proteins), and development of the yeast models forstudying mammalian and humanamyloids, involved in diseases.Our research has demonstrated thatprionscan be induced by transient protein overproduction and discovered the crucial role of chaperones inprionpropagation, shown evolutionary conservation ofprion-formingproperties, established a yeast system for studying species-specificity ofpriontransmission,and uncovered links between prions,cytoskeletalnetworks and protein quality control pathways.

Engineering of genetically encoded biosensors Quantitative fluorescence microscopy and image analysis Computational models of gene regulatory networks Transcriptional regulation and developmental biology of plants The past fifteen years has seen dramatic advancements in genome sequencing and editing. The cost of sequencing a genome has decreased by two orders of magnitude, giving rise to new systems-level approaches to biology research that aim to understand life as an emerging property of all the molecular interactions in an organism. At the same time, technologies that allow site-specific modifications of the genome are enabling researchers to manipulate multicellular organisms in unprecedented ways. From reductionist approaches to systems biology, and from conventional plant breeding to synthetic biology, the future of plant biology research relies on the adoption of computational methods to analyze experimental data and develop predictive models. In biomedicine, mathematical models are already revolutionizing drug discovery; in agriculture, they have the potential to generate more efficient, faster growing crop varieties. The goal of the Cheung lab is to bring quantitative techniques and mathematical modeling to plants in order to gain systems-level insight into their physiology and development - particularly to understanding how metabolic and gene regulatory networks interact to control homeostasis and growth.
