Fluctuations in auxin levels depend upon synchronicity of cell divisions in a one-dimensional model of auxin transport (2023)
Journal Article

Auxin is a well-studied plant hormone, the spatial distribution of which remains incompletely understood. Here, we investigate the effects of cell growth and divisions on the dynamics of auxin patterning, using a combination of mathematical modelling...

In silico evidence for the utility of parsimonious root phenotypes for improved vegetative growth and carbon sequestration under drought (2022)
Journal Article

Drought is a primary constraint to crop yields and climate change is expected to increase the frequency and severity of drought stress in the future. It has been hypothesized that crops can be made more resistant to drought and better able to sequest...

Modeling root loss reveals impacts on nutrient uptake and crop development (2022)
Journal Article

Abstract Despite the widespread prevalence of root loss in plants, its effects on crop productivity are not fully understood. While root loss reduces the capacity of plants to take up water and nutrients from the soil, it may provide benefits by decr...

The effect of renewable energy incorporation on power grid stability and resilience (2022)
Journal Article

Contemporary proliferation of renewable power generation is causing an overhaul in the topology, composition, and dynamics of electrical grids. These low-output, intermittent generators are widely distributed throughout the grid, including at the hou...

Show me the money: Income inequality and segregation in UK cities (2022)
Journal Article

The social geography of cities is argued to be changing globally; rising economic inequality is associated with increasing segregation. Yet, income inequality has been predominantly mobilised through national and regional imaginaries. In cities, a nu...

Non-cell autonomous and spatiotemporal signalling from a tissue organizer orchestrates root vascular development (2021)
Journal Article

During plant development, a precise balance of cytokinin is crucial for correct growth and patterning, but it remains unclear how this is achieved across different cell types and in the context of a growing organ. Here we show that in the root apical... Read More about Non-cell autonomous and spatiotemporal signalling from a tissue organizer orchestrates root vascular development.

Cauliflower fractal forms arise from perturbations of floral gene networks (2021)
Journal Article

Throughout development, plant meristems regularly produce organs in defined spiral, opposite, or whorl patterns. Cauliflowers present an unusual organ arrangement with a multitude of spirals nested over a wide range of scales. How such a fractal, sel...

A network of transcriptional repressors modulates auxin responses (2020)
Journal Article

The regulation of signalling capacity, combined with the spatiotemporal distribution of developmental signals themselves, is pivotal in setting developmental responses in both plants and animals. The hormone auxin is a key signal for plant growth and... Read More about A network of transcriptional repressors modulates auxin responses.

Understanding Microwave Heating in Biomass-Solvent Systems (2020)
Journal Article

A new mechanism is proposed to provide a viable physical explanation for the action of microwaves in solvent extraction processes. The key innovation is Temperature-Induced Diffusion, a recently-demonstrated phenomenon that results from selective hea... Read More about Understanding Microwave Heating in Biomass-Solvent Systems.

Cascading failures in networks of heterogeneous node behavior (2020)
Journal Article

Variability in the dynamical function of nodes comprising a complex network impacts upon cascading failures that can compromise the network's ability to operate. Node types correspond to sources, sinks or passive conduits of a current ow, applicable... Read More about Cascading failures in networks of heterogeneous node behavior.

Chaos in a ring circuit (2019)
Journal Article

A ring-shaped logic circuit is proposed here as a robust design for a True Random Number Generator (TRNG). Most existing TRNGs rely on physical noise as a source of randomness, where the underlying idealized deterministic system is simply oscillatory... Read More about Chaos in a ring circuit.

Local negative circuits and cyclic attractors in Boolean networks with at most five components (2019)
Journal Article

We consider the following question on the relationship between the asymptotic behaviors of asynchronous dynamics of Boolean networks and their regulatory structures: Does the presence of a cyclic attractor imply the existence of a local negative circ...

The logic of the floral transition: reverse-engineering the switch controlling the identity of lateral organs (2017)
Journal Article

Much laboratory work has been carried out to determine the gene regulatory network (GRN) that results in plant cells becoming flowers instead of leaves. However, this also involves the spatial distribution of different cell types, and poses the quest...

A stochastic multicellular model identifies biological watermarks from disorders in self-organized patterns of phyllotaxis (2016)
Journal Article

Exploration of developmental mechanisms classically relies on analysis of pattern regularities. Whether disorders induced by biological noise may carry information on building principles of developmental systems is an important debated question. Here...

A modular analysis of the Auxin signalling network (2015)
Journal Article

Auxin is essential for plant development from embryogenesis onwards. Auxin acts in large part through regulation of transcription. The proteins acting in the signalling pathway regulating transcription downstream of auxin have been identified as well... Read More about A modular analysis of the Auxin signalling network.

Inference of the Arabidopsis lateral root gene regulatory network suggests a bifurcation mechanism that defines primordia flanking and central zones (2015)
Journal Article

A large number of genes involved in lateral root (LR) organogenesis have been identified over the last decade using forward and reverse genetic approaches in Arabidopsis thaliana. Nevertheless, how these genes interact to form a LR regulatory network...

Cytokinin signalling inhibitory fields provide robustness to phyllotaxis (2013)
Journal Article

How biological systems generate reproducible patterns with high precision is a central question in science. The shoot apical meristem (SAM), a specialized tissue producing plant aerial organs, is a developmental system of choice to address this quest...
