Model Theory and Complexity Theory

This presentation explores the intersection of finite model theory and complexity theory, with a focus on descriptive complexity—a framework that classifies computational problems based on the logical languages needed to express them. It highlights classical results such as Fagin’s theorem (NP = Σ₁¹) and Immerman’s characterization of P, and introduces

A THEORY OF COMPLEXITY, CONDITION, AND ROUNDOFF [PDF]

Forum of Mathematics, Sigma, 2015
We develop a theory of complexity for numerical computations that takes into account the condition of the input data and allows for roundoff in the computations. We follow the lines of the theory developed by Blum, Shub and Smale for computations over $\mathbb{R}$ (which in turn followed those of the classical, discrete, complexity theory as laid down ...

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

FEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Community Networks and the Nature of Emergence in Civil Society

Cosmopolitan Civil Societies: An Interdisciplinary Journal, 2010
Our research challenges the limitations of extant knowledge of social formation by its focus on the ordinary, everyday lived reality of maintaining community and on identifying its operations from the internal perspective of civil society.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Prosperous teaching and the thing of darkness: Raising a Tempest in the classroom

Cogent Arts & Humanities, 2016
This essay uses Shakespeare’s The Tempest as a way of conceptualising modern institutional education. The over-systematisation of formal education which characterises professional teaching and learning in the twenty-first century is designated “SysEd ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.
