About

// bio

I am a PhD researcher and educator in Computer Science with interests in cybersecurity, artificial intelligence, machine learning, networking, SATCOM security, and AI-enabled medical technologies.

My research focuses on developing intelligent systems for anomaly detection, jamming detection, secure communications, and AI-assisted monitoring systems. I also work with networking technologies including BGP, OSPF, MPLS, EVPN, VXLAN, SD-WAN, and network automation.

I enjoy building practical research prototypes, exploring startup ideas, and translating academic research into real-world solutions.

Research Areas

// focus
[CYBERSEC]

Cybersecurity

Protecting modern communication, computing, and connected systems from evolving threats — anomaly detection, network security, adversarial behavior detection, medical device cybersecurity, intrusion detection, and AI/ML applied to cyber defense. Focused on intelligent security mechanisms that identify abnormal behavior, detect attacks in real time, and improve resilience across critical and distributed systems.

[COMMS]

Communications

Secure and reliable wireless and satellite communication systems — SATCOM security, jamming detection, communication-system telemetry, signal quality monitoring, interference analysis, and AI-assisted communication system supervision. Combining communication-system modeling with ML to detect abnormal conditions, improve reliability, and support intelligent resource management.

[NETWORK]

Computer Networking

Routing, switching, network architecture, network security, and next-generation networking — BGP, OSPF, MPLS, EVPN, VXLAN, SD-WAN, network automation, and software-defined networking. Focused on how modern networks can be designed, monitored, secured, and optimized for scalability, reliability, and performance.

[DATA-SCI]

Data Science

Extracting meaningful information from complex datasets using statistical analysis, machine learning, deep learning, and data-driven modeling — time-series analysis, anomaly detection, predictive modeling, feature engineering, and model evaluation, applying deep learning architectures to cybersecurity, communications, and intelligent monitoring systems.

Adversarial Patch Effectiveness on UAVs/Drones

Student Researcher: Alexander Pickett · Mentor: Sai Karthik Garnepudi

Wichita State University

Investigated the effectiveness of adversarial patches against UAV/drone-based computer vision systems, exploring how specially designed visual patterns can interfere with AI object-detection models used by autonomous aerial systems. Evaluated different adversarial patch configurations to understand their ability to reduce detection confidence and cause vision-based systems to misidentify or fail to recognize targeted objects — providing practical insight into cybersecurity risks in AI-enabled autonomous systems, drones, and computer vision, and the need for robust ML models that withstand adversarial attacks.
