About
I am a doctoral candidate in the Professional Doctorate in Accounting and Business Administration at Fucape Business School, holding a dual degree in the Doctorate in Management from Universidade da Beira Interior (UBI), in Portugal. I came to research after more than two decades in C-level positions: I am CEO of Brizztech Climatizadores and served as Chief Operating Officer in the United States.
I am completing a professional master's degree in Corporate Governance at FMU, with a dissertation on information asymmetry between the CEO and the board and its impact on the quality of strategic decisions, supervised by Prof. Dr. Leonardo Fabris Lugoboni. My background also includes an Executive MBA in Industrial Management from FGV, an MBA in Compliance and Risk Management, and certification as an Advisory Board Member (ConCertif®) from CELINT.
The doctoral thesis topic is still being defined, within the Strategy and Organization research line.
The doctoral coursework is confirmed for the 2026–2028 period, combining courses in strategy, corporate finance, quantitative methods and research methodology at Fucape with advanced management units at UBI. The move to Portugal is planned for June 2027, roughly two months before UBI's first semester begins.
My thesis follows the three-article format, combining technological and scientific output, with additional international publication requirements arising from the dual degree.

This study analyzes how information asymmetry shapes the relationships between CEOs and advisory boards and its implications for decision-making in corporate governance. Drawing on a systematic literature review grounded in the PRISMA protocol, it examines evidence from research published in high-impact journals, focusing on the informational and relational mechanisms that structure these interactions. The results indicate that information asymmetry is not limited to a governance failure but constitutes a multidimensional phenomenon that simultaneously enables and compromises decision quality. Vertical asymmetry stems from CEO control over the informational flow, whereas horizontal asymmetry emerges from social ties that create informal information channels. These mechanisms can broaden access to knowledge but may also reduce monitoring independence. The study argues that the effectiveness of advisory boards depends on the balance between access to information and critical autonomy. As a contribution, it integrates the vertical and horizontal dimensions of information asymmetry and broadens the understanding of informational dynamics within advisory structures.

Information Asymmetry in Board Decision-Making: A Systematic Literature Review

Systematic review following the PRISMA protocol · venue to be defined
Abstract
This study examines how information asymmetry (ASIN) shapes the relationships between CEOs and advisory boards and its implications for decision-making in corporate governance. Drawing on a systematic literature review grounded in the PRISMA protocol, evidence from research published in high-impact journals is examined, with a focus on the informational and relational mechanisms that structure these interactions. The results indicate that ASIN is not merely a governance failure but a multidimensional phenomenon that simultaneously enables and compromises decision quality. Vertical ASIN stems from CEO control over the informational flow, whereas horizontal ASIN emerges from social ties that create informal information channels. These mechanisms can broaden access to knowledge but may also reduce monitoring independence. The study argues that the effectiveness of advisory boards depends on the balance between access to information and critical autonomy. As a contribution, it integrates the vertical and horizontal dimensions of ASIN, drawing on a sample of 14 studies, and broadens the understanding of informational dynamics within advisory structures.

Códigos de conduta das empresas da B3: influências do setor de atuação e da estrutura de governança corporativa

Abstract
Purpose: to analyze how business sector and corporate governance level influence the structure and content of the codes of conduct of companies listed on B3. Design/methodology/approach: descriptive, documentary research based on a sample of 232 codes of conduct from companies in the New Market, Level 2, and Level 1 listing segments, analyzed through categorical content analysis (Bardin) and Pearson's chi-square test, covering 16 ethical themes identified in the literature. Originality/Relevance: despite the growing use of codes of conduct as corporate governance instruments, the literature still lacks studies relating their structure and content to companies' business sector and governance level, a gap this study addresses in light of institutional isomorphism theory. Findings: a common core of themes widely disseminated among companies was identified — conflict of interest, moral and sexual harassment, discrimination, and the environment. Themes such as privileged information, gifts and favoritism, nepotism, whistleblowing channels, and psychotropic substance abuse showed statistically significant differences according to business sector and corporate governance level. Contributions: the findings corroborate the institutional isomorphism perspective and offer input for boards of directors and compliance areas in drafting codes more aligned with good practices and sector-specific particularities.

Quando as metas corroem o que pretendem promover: uma revisão sistemática das consequências disfuncionais das metas corporativas

Abstract
our translation; the original has no version in this language
Objective: to systematize and explain the dysfunctional consequences associated with corporate performance targets, the behavioral and managerial mechanisms that sustain them, and the conditions under which they intensify. Methods: a systematic review conducted in accordance with PRISMA 2020, searching the EBSCO Business Source Complete database in May 2026 and restricted to peer-reviewed articles published between 2021 and 2026 in SJR Q1 or Q2 journals; of the 173 records identified, 17 formed the corpus, analyzed through a qualitative synthesis structured by the typology of Franco-Santos and Otley (2018). Results: the five dysfunctional manifestations do not operate discretely, since 15 of the 17 studies cut across more than one category, and the transformation of social relationships, the most frequent one, works as the transmission channel for the others. The mechanisms identified include moral disengagement, emotional exhaustion, and fear of failure, modulated by design parameters, governance structures, and individual characteristics. Conclusions: deviance emerges as a rational response to the design of the measurement system rather than as an episodic moral failure, which shifts managerial intervention from controlling the individual to designing the targets.

Gerenciando riscos corporativos: uma análise da taxonomia de Kaplan e Mikes

Corporate risk management has evolved from an isolated function into an integrated and strategic process central to contemporary governance. This article proposes an analytical framework to classify and manage risks based on the taxonomy of Kaplan and Mikes, distinguishing preventable, strategic, and external risks. It argues that each category requires distinct approaches, tools, and control systems, avoiding one size fits all solutions. The study discusses the role of a Risk Management Office as a mechanism for organizational coordination, as well as the contribution of the Chief Risk Officer in integrating ERM into decision making. The findings indicate that a differentiated approach to risk management improves resource allocation, strengthens the ability to anticipate and respond to threats, and contributes to greater resilience and higher quality corporate governance.

Os desafios multifacetados do líder trifuncional no conselho consultivo: uma jornada ética e de valores fundamentada na governança corporativa

Abstract
our translation; the original has no version in this language
This chapter analyzes the ethical and governance challenges of the tri-functional leader, a professional who simultaneously holds the positions of minority shareholder, CEO, and chair of the advisory board. It is argued that this overlap blurs the boundaries between ownership, strategic execution, and the conduct of the collegiate body's work, increasing the risk of conflicts of interest. The dilemmas specific to each role are examined: as shareholder, the ownership stake shapes the perception of risk; as CEO, pressure for results shifts the focus to execution and accountability; as chair, what is expected is neutrality in conducting proceedings, faithful minutes, custody of confidential information, and the facilitation of dialogue between management and board members. Privileged access to information is identified as the most sensitive point: the leader must mitigate asymmetries and adverse selection by providing complete, timely, and clear data, above all to independent board members, whose presence is treated as a pillar that strengthens governance rather than an obstacle. Transparency, fairness, accountability, and corporate responsibility are discussed as standards of conduct, together with practical mitigation mechanisms: explicit delimitation of roles, declaration of conflicts, abstention from deliberations, and direct channels with board members. It is concluded that advanced training in governance supplies the analytical lenses, but personal integrity guides decisions under pressure; success lies not in the absence of challenges but in the capacity to face them without compromising the company's continuity.
