Criminologist
I read behavior for a living — offender profiling, signature and modus-operandi analysis, geographic profiling. Then I design and build the systems that put it to work: interfaces, dashboards and data visualizations, hand-coded from first sketch to shipped front-end.
Behavioral analysis and offender typology — and the design and code that carry them.
I am a criminologist and criminal profiler working between the interview room and the dataset. My focus is behavioral analysis: reading signature behavior, modus operandi and victimology to build offender typologies that hold up under scrutiny.
I hold an M.S. in Criminology from the University of Pennsylvania (Summa Cum Laude) and contributed to the FBI Behavioral Science Unit as an academic intern, reviewing case files for unsolved violent crimes. A parallel background in cybersecurity and digital forensics lets me follow offenders across both physical and digital ground.
Behavior leaves a pattern. The pattern leaves a signature. The signature identifies the offender.
I am also a designer and developer. A finding is only worth the decision it produces, so I don't stop at the report: I design the interface, then write the HTML, CSS and JavaScript behind it — dashboards, data visualizations and forensic diagrams built by hand, not assembled from a template.
Criminology, sociology, cybersecurity and visual design — four disciplines, one method.
Thesis — “Predictive Behavioral Markers in Serial Property Crime: A Mixed-Methods Approach.”
Capstone — “Socioeconomic Disparities and Recidivism Rates in the California Correctional System.”
Capstone — “Securing Small Business Networks Against Ransomware Attacks.”
Six assignments: academic research, a federal internship, security operations, design and code.
Collaborated with a faculty team on a longitudinal study analyzing behavioral patterns in 300+ incarcerated individuals to refine risk assessment models. Developed a proprietary coding framework for qualitative interview data, increasing inter-rater reliability by 22%. Presented preliminary findings at the 2025 American Society of Criminology Annual Conference.
Assisted supervisory special agents in reviewing case files for unsolved violent crimes, identifying signature behaviors and modus operandi. Conducted comprehensive literature reviews on victimology and offender typologies, contributing to two active investigative case summaries. Participated in weekly threat assessment briefings and critical incident debriefings.
Monitored network traffic and analyzed security logs for over 200 client servers, identifying and mitigating potential threats in real time. Conducted vulnerability assessments and penetration testing on internal systems, reducing security breaches by 30%. Produced cybersecurity awareness material for corporate clients and worked with law enforcement on digital evidence preservation for three active cybercrime investigations.
Designed data dashboards and infographics for academic research papers, translating complex criminological data into accessible visual formats. Created court-ready forensic diagrams and crime scene reconstructions for a private investigative firm. Developed branding for three non-profits focused on community safety and designed UI/UX mockups for a suspicious-activity reporting app.
Managed and cleaned large datasets (n=5,000+) using SPSS and R to analyze the correlation between community resources and juvenile delinquency. Co-authored a working paper titled “Urban Ecology and Youth Offending Patterns,” under review at the Journal of Quantitative Criminology. Trained and supervised five undergraduate volunteers in data collection and ethical research standards.
Assisted in securing school network infrastructure against potential cyber threats. Provided technical support to staff and students, troubleshooting hardware and software issues. Produced user-friendly visual guides for cybersecurity best practices, distributed to 2,000+ employees.
Six working modules, from field profiling to the interfaces and code that present it.
Interfaces, dashboards and visual systems — designed, prototyped and shipped by hand.
I don't hand my work to a template. Every interface I produce is designed and built from scratch: a layout and type system decided first, then written by hand in semantic HTML, modern CSS and plain JavaScript — no framework standing between the idea and the screen.
For me design and development are one discipline, not two hand-offs. A risk assessment is only useful if the person reading it can act on it, so the last mile of every project is the same: turn dense findings into something clear, fast and honest on screen — legible data tables, defensible charts, diagrams that survive a courtroom.
A finding is worth the decision it produces. Everything I build exists to close that distance.
This page is the working demonstration: a hand-written WebGL scene, an inertial scroll, a full print stylesheet and a strict security policy — built with no framework, no build step and no third-party request.
