If there’s anything you need to know about miss Cheryl Andrea Fernando, it’s most definitely her love-hate relationship with AI. Sure, AI has helped her debug 1 in 5 bugs without making it significantly worse, but it’s the other 4 instances that make her question why she approached AI for help in the first place. Cheryl has a background in computer science and engineering, with much interest in cybersecurity and much more interest in wanting to help safeguard the world against the exploitative nature of AI. Just as a social human being, noticing how often people gravitate towards asking ChatGPT without a second thought even for the most simplest task, almost feels like there’s a growing lack of originality, creativity and cognitive ability making them feel like human side effects of AI. Currently working at SURF on the very same topic of AI Bot Mitigation, she hopes to come up with a solution that could help content owners safe guard their content from the pesky AI scraping bots that crawl the internet endlessly to feed their ever-growing machine learning model. Cheryl has a lot of creative passions and hobbies like crochet, sewing and music, accompanied by being chronically online and missing the days she could quite easily tell when something was AI generated.

After studying at the radboud university and doing internships at SURF I started my own company building GRC and cybersecurity software.

Beside that me and a team of students are building an open source vulnerability management stack cofunded by SIDN and NLNET, where the first big chunks are done and open sourced.

I like cyber, programming, have an interesting in AI and did a minor on that subject and in my free time like to watch cycling and cook food.
