Digital Identity Security · Usability · Human-Centered Cybersecurity

I am an Assistant Professor of Computer Science and a cybersecurity researcher working on digital identity, authentication security, security usability, and the interaction between people and security systems.

I study how security mechanisms behave in real-world use, where technical design, human decisions, interface choices, and attacker behavior all come together.

What I Do

I work where security, technology, and human behavior meet.

My work focuses on the intersection of cybersecurity, privacy, usability, and user interaction. I am particularly interested in security mechanisms that require people to interpret information, recognize risk, and make decisions during authentication.

I study security systems as people actually use them, not only as they are expected to operate in ideal conditions. That means looking beyond whether a protocol is technically sound and asking what happens when the system is deployed, the interface becomes part of the decision, and the user is distracted, under pressure, or facing a convincing attack.

My goal is to contribute to systems that provide strong technical protection while also making security decisions clearer and more manageable for the people who depend on them.

Why this matters

A technically strong security mechanism can still become vulnerable when its interface is confusing, its warnings are easy to ignore, or its protection depends too heavily on constant user attention.

I therefore treat usability as part of security design rather than something added after the security mechanism has already been built.

Areas of Expertise

Security problems I work on.

My work spans authentication technologies, password security, phishing-resistant systems, and the human decisions that influence whether security mechanisms succeed in practice.

Problems I Work On

From security challenges to systems people can trust.

I focus on security problems that emerge when technical protection, attacker behavior, system design, and human decision-making interact.

Is this authentication request legitimate?

I study how authentication requests can provide enough context for users to distinguish a legitimate action from an unexpected or fraudulent request.

How do we strengthen security without creating unnecessary friction?

I examine how authentication mechanisms can provide strong protection while keeping security decisions clear, understandable, and manageable for users.

How can systems depend less on perfect user attention?

I explore designs that make the system itself more resistant to phishing and misuse instead of relying entirely on users to recognize every threat.

Focus Areas

Where my work is concentrated.

These areas bring together security research, system design, authentication technology, and the way people interact with security decisions.

Push Authentication

I study how authentication prompts, contextual information, and interface design influence a user's ability to recognize legitimate and fraudulent requests.

Store-less Password Managers

I investigate approaches for generating strong, site-specific credentials without relying on a traditional vault that stores every password.

Phishing-Resistant Systems

I examine technologies and system designs that reduce the opportunity for phishing attacks to succeed, including cases where an attacker can present a convincing interface to the user.

Security Usability

I study how strong security controls can remain understandable and practical without creating unnecessary complexity for the user.

Security Decisions & User Behavior

I examine how interface design, repeated prompts, context, time pressure, and user attention can influence security decisions.

Digital Identity & Access Security

I am interested in systems that protect digital identity while balancing strong authentication, access control, security, and user experience.

What I Bring

From research evidence to clearer security decisions.

I approach cybersecurity problems by combining technical analysis with an understanding of how systems behave when people use them in real environments.

Evidence-Driven Security Analysis

Examining security mechanisms, interfaces, attacks, and user behavior to identify where risks appear and where designs can be improved.

Making Complex Security Understandable

Translating technical security problems and research findings into clear explanations that can support researchers, technical teams, and decision-makers.

Connecting Security with User Experience

Treating technical protection and usability as parts of the same security system rather than competing objectives.
