Key research themes

1. How does the DRAGON lattice code perform in simulating neutron transport and reactor physics benchmark problems for different reactor types?

This research area focuses on benchmarking and validating the DRAGON code's capability to accurately simulate neutron behavior and reactor physics parameters in Pressurized Heavy Water Reactors (PHWR), Boiling Water Reactors (BWR), and Mixed Oxide (MOX) fuel assemblies. Accurate neutronic modeling at the lattice level is crucial for reactor design, safety, and fuel cycle analysis. The research explores methodological choices such as the use of collision probability and Method of Characteristics (MOC) solving techniques, sensitivity analyses of solver parameters, and comparisons against experimental data and Monte Carlo reference codes.

Key finding: This paper demonstrates DRAGON's effective simulation of both PHWR and BWR lattice benchmark problems using a collision probability method and updated nuclear data libraries, achieving results consistent with multiple... Read more
Key finding: Through a detailed sensitivity study of Method of Characteristics (MOC) parameters within DRAGON5, this paper identifies optimal settings—such as azimuthal angles between 16 and 32, ray density above 10 cm⁻¹, and an 8×8... Read more

2. What socio-cultural dynamics and discursive mechanisms contribute to gender erasure and male preservation in Dragon Magazine and the tabletop role-playing game community?

This research theme addresses the historical and discursive processes that have marginalized women's participation in tabletop role-playing games (TRPGs), focusing on Dragon Magazine as a key cultural artifact. It investigates linguistic practices, representations, and gendered socialization that sustain a male-dominated TRPG subculture, influencing contemporary issues of gatekeeping and gender inclusivity within gaming communities.

Key finding: Using critical discourse analysis of 45 Dragon Magazine articles, this study identifies textual mechanisms—such as predominant masculine pronoun usage, characterization of women in protective and comedic roles, and... Read more

3. How do dragons function as symbolic and narrative entities across media, cultures, and genres, and what new interpretations emerge in contemporary literature and digital media?

This theme investigates the multifaceted symbolism of dragons, spanning historical mythology, cross-cultural interpretations, literary role reversals, and digital cultural artifacts. It explores dragons as creatures embodying cultural power, wisdom, and transformation with emphasis on dualities such as destruction and protection. The research also considers modern reinterpretations where dragons shift from adversaries to protagonists, and the impact of programming languages on poetic conceptions of dragons, revealing evolving narratives and identities influenced by technology and global cultural exchange.

Key finding: This study analyzes two young adult novels where dragons assume the hero role, challenging traditional Western paradigms that cast dragons as villains. By applying Joseph Campbell's hero's journey framework, it demonstrates... Read more
Key finding: The book synthesizes a vast iconographic, literary, and mythological corpus to argue that the dragon's defining characteristic is its inherent ambiguity—embodying both destructive and protective forces in dualistic... Read more
Key finding: Analyzing the 2013 poetry collection 'Dragon Logic', this article elucidates how computational programming languages and print poetic form interlace to create multilayered, feedback-driven textual architectures. The study... Read more
