Professional Certificate in Cybersecurity: IT and Data Security in the Age of AI

“My name is Chad Waltz from Des Moines, Iowa. I work at an insurance company as a Software Engineer and currently work with .NET programming while preparing to start with Node.js. I enjoyed the weekly Saturday sessions, and the projects exposed me to new technologies. I have always been interested in security and protecting computers and personal information. I learned by creating Virtual Machines and working on projects focused on viruses and security. We are also starting a central logging system to help troubleshoot issues.”

Professional Certificate in Cybersecurity: IT and Data Security in the Age of AI

“I am Riccardo Cast from Miami, Florida, and I work at Cleveland Clinic Foundation as an Enterprise Infrastructure Support Manager. I recently completed the JHU Professional Certificate in Cybersecurity Program. I wanted to gain a wider knowledge of Cybersecurity and better understand how AI can play a significant role in this field. I now have a broader understanding of Cybersecurity and the technologies shaping the industry. While I am not responsible for the cybersecurity division in my company, I can now better understand what they do and why they do it.”

Professional Certificate in Cybersecurity: IT and Data Security in the Age of AI

“I am Kojo O. Acheampong from New York City, and I work as an elementary school teacher at Laboratory Charter School. I recently completed the JHU Professional Certificate in Cybersecurity Program and am proud of this experience. I am hopeful about securing a new role as a Cybersecurity Specialist. My journey into cybersecurity was a mix of problem-solving and challenges, but it was rewarding when concepts came together. I chose this program because I wanted a new intellectual challenge, a fresh start, and the opportunity to build a career in cybersecurity. I learned a great deal about Cloud Security, hacking, and using Kali Linux. I am confident that I will apply the skills and knowledge gained from this program in my future endeavors.”

Roney Lima Do Nascimento

Certificate Program in Applied Generative AI

“I recently completed the Certificate Programme in Applied Generative AI and Agentic AI, where my project involved building a production-grade AI pipeline to ingest and semantically index 112 research papers and support grant proposal drafting. Using LangChain, Chroma DB, and GPT-4, I developed a seven-stage system covering topic extraction, semantic filtering, compliance checks, human review, and final consolidation. What stood out to me was the programme’s strong focus on foundations, including Transformer Architectures, Retrieval-Augmented Generation (RAG), Fine-Tuning, and Agentic Workflows, along with a thoughtful discussion of limitations and evaluation. As a PhD candidate in Pure Mathematics, I value building AI systems that are explainable, testable, and methodologically grounded. The knowledge and skills I gained through the programme align closely with my work in AI for education, including RAG-based learning assistants, adaptive platforms, AI literacy initiatives, and my book, Generative AI for Teachers.”

Chad Melone

Applied Generative AI and Agentic AI Program

“The Certificate Program in Applied Generative AI and Agentic AI delivered exactly what I was looking for. By the end of the program, I had developed a conceptual Retrieval-Augmented Generation (RAG) architecture for a new business venture and gained the strategic framework needed to guide government clients in the safe adoption of AI technologies. The curriculum balanced technical depth with accessibility, making it valuable for both non-coders and professionals transitioning into AI. I had the opportunity to work hands-on with advanced models, including deploying Llama models locally, while benefiting from the support and structure needed to succeed. Overall, I am extremely pleased with the practical value of the program and would highly recommend it to anyone looking to develop hands-on skills in Generative AI and Agentic AI.”
