Magical Implementation
Joint work with Jacob Glazer. Abstract: A principal needs to decide which of two parties deserves a prize. Each party privately observes the state of nature that determines which of them deserves the prize. The principal presents each party with a text that truthfully describes the conditions for deserving the prize and asks each of… Continue Reading Magical Implementation

Deep Learning for approximating solutions to hard computational problems indirectly
Abstract: Computational reduction serves as a powerful tool in optimization by enabling the translation between different computational problems while preserving key structural and computational properties. This allows one problem to be reformulated in terms of another, often facilitating the solution of otherwise complex problems. Since reductions are mostly manual, it is plausible that alternative, better… Continue Reading Deep Learning for approximating solutions to hard computational problems indirectly

GRD and the Other GRD: Goal Recognition Design for Guardrail Design
Abstract: Ensuring that Large Language Models comply with desired behavioral specifications, such as safety constraints, stylistic requirements, or task instructions, remains a key challenge due to their open-ended generative nature. We propose a novel compliance framework based on Goal Recognition Design, a classical planning technique that reduces ambiguity over an agent’s goals by strategically modifying… Continue Reading GRD and the Other GRD: Goal Recognition Design for Guardrail Design

Moonshot: The role of courage in stretch goal pursuit – Job Talk
ABSTRACT In recent years, organizations have been facing increasingly volatile environments that require decision makers to operate under conditions of uncertainty and risk. Alongside these conditions, organizations – and societies at large – face ‘grand challenges’, complex and uncertain problems such as climate change and financial instability, as well as opportunities such as rapid innovation… Continue Reading Moonshot: The role of courage in stretch goal pursuit – Job Talk

Emergent population dynamics of random walkers with cooperative reproduction and spatial selection
Abstract: We extend the $N$ branching Brownian motions model of population invasion to higher-order asexual reproduction. Increasing reproduction order leads to qualitative changes: invasion fronts generically cease to exist beyond binary reproduction; and in the binary case itself, their speed becomes diffusion-independent. Ternary reproduction shows critical behavior, with collapse into a strongly localized `invasion bullet’… Continue Reading Emergent population dynamics of random walkers with cooperative reproduction and spatial selection
