## Education and early career
Ellison earned a Ph.D. in geology from [Brown University](https://www.edgepedia.org/brown-university), then spent four years at Princeton University as a postdoctoral fellow. He followed this with five and a half years as a staff scientist at [Argonne National Laboratory](https://www.edgepedia.org/argonne-national-laboratory), where he twice received the Pacesetter Award for Excellence in Achievement and the Director's Outstanding Achievement Award.[1](http://hdl.handle.net/10829/20975)
## Career at Corning
Ellison joined Corning Incorporated in 1996 and rose to Corporate Fellow, a rank the company describes as the pinnacle of its technical recognition, "reflecting rare and truly exceptional career achievements."[1](http://hdl.handle.net/10829/20975) As of 2012 he was author or co-author of 36 patents, 48 pending patent applications, and 44 peer-reviewed publications, with inventions supporting Corning's commercial success in the Display Technologies and Specialty Materials market segments.[1](http://hdl.handle.net/10829/20975) A 2008 Corning patent application, on which he was a named inventor, describes an alkali aluminosilicate glass that is chemically strengthened and down-drawable, with a melting temperature below about 1650 °C, a liquidus viscosity of at least 130 kpoise, and ion exchange to a depth of at least 30 μm; this composition family underlies [Gorilla Glass](https://www.edgepedia.org/gorilla-glass)-type cover plates.[3](https://pubchem.ncbi.nlm.nih.gov/patent/US-2008286548-A1)
## Research and contributions
**Viscosity and the glass transition.** In a 2009 PNAS paper with J. C. Mauro, [Yuanzheng Yue](https://www.edgepedia.org/yuanzheng-yue), Prabhat K. Gupta, and Douglas C. Allan, Ellison addressed a long-standing problem: existing viscosity models, such as the Vogel-Fulcher-Tammann (VFT) and Avramov-Milchev (AM) equations, exhibit systematic error when extrapolating to low temperatures.[2](https://doi.org/10.1073/pnas.0911705106) The paper presents a model with the same number of parameters as VFT and AM but with a clear physical foundation based on the temperature dependence of configurational entropy, the entropy associated with the many ways atoms can be arranged in a glass. It predicts low-temperature isokoms (curves of equal viscosity) accurately without any singularity at finite temperature. Because the leading theories of an ideal glass transition, including the Kauzmann entropy catastrophe, require such a singularity, the authors state that their results cast doubt on the existence of a Kauzmann entropy catastrophe and an associated ideal glass transition.[2](https://doi.org/10.1073/pnas.0911705106)
A 2010 companion study in the Journal of Chemical Physics gave the framework experimental footing. Current models of the glass transition implicitly assume that the thermal expansion coefficient of a glass-forming system is the sum of vibrational and configurational contributions, an assumption made without rigorous justification. The paper presents a statistical mechanical analysis resolving the two contributions and shows experimental proof of their separability in Corning Jade glass.[4](https://doi.org/10.1063/1.3481441)
**Room-temperature relaxation.** The legend that cathedral windows thicken at their bases because glass flows has circulated for centuries. In a 2013 [Physical Review Letters](https://www.edgepedia.org/physical-review-letters) paper, Ellison and colleagues reported quantitative measurement of glass relaxation at room temperature, finding that Corning Gorilla Glass shows measurable and reproducible relaxation under ambient conditions. The relaxation follows a stretched exponential decay rather than simple exponential relaxation, with a stretching exponent of β = 3/7 that follows a theoretical prediction made by J. C. Phillips for homogeneous glasses.[5](https://doi.org/10.1103/PhysRevLett.110.265901)
**Collagen-mimetic peptides.** In a marked change of subject, Ellison's later work applies self-assembly and thermodynamic reasoning to collagen, the most abundant protein in humans and the major component of human skin. Collagen-mimetic peptides (CMPs) are short peptides that fold into collagen's triple-helical structure and can anneal to damaged collagen in vitro and in vivo. A 2020 [Journal of the American Chemical Society](https://www.edgepedia.org/journal-of-the-american-chemical-society) paper evaluated disulfide-templated CMP "dimers" and found that such linked pairs retain their collagen-like structure even without a third strand, but only when their strands can adopt a triple-helical fold, a result that explains the success of sticky-ended CMP association and informs synthetic collagen design.[6](https://doi.org/10.1021/jacs.9b07583)
The biomedical thread runs through several 2018–2024 papers. A 2024 Advanced Science paper describes sticky-ended symmetric self-assembly (SESSA), an approach that maximizes interactions between the strands of the triple helix, allowing CMPs to assemble into robust synthetic collagen nanofibers. The study found that 33-residue CMPs not only self-assemble through sticky ends but also form hydrogels, with behavior consistent across multiple scales and a clear link between triple-helical architecture and hydrogel properties.[7](https://doi.org/10.1002/advs.202303228) Synthetic, chemically defined hydrogels matter because animal-sourced collagen hydrogels, widely used as extracellular-matrix mimics in tissue engineering, suffer from reproducibility, immunogenicity, and contamination problems.[7](https://doi.org/10.1002/advs.202303228) Related work includes a cyclic peptide mimic of damaged collagen with potential use in diagnosing and treating fibrotic diseases and wounds,[8](https://doi.org/10.1021/acs.biomac.0c00103) a fluorescent CMP that labels Group A Streptococcus cells but not bacteria lacking collagen-like surface proteins, consistent with streptococcal collagen forming triple helices with damaged collagen in a wound bed,[9](https://doi.org/10.1021/acsinfecdis.0c00073) and a modular strategy in which conjugating salicylic acid to a CMP retains the sunscreen filter on collagen-containing skin surrogates after repeated washing.[10](https://doi.org/10.1039/c8ob01773e)
