Forum:Spoiler:chell's parent at aperture is her dad?

After searching on the interwebs for a picture of the science project with "by chell" on it i noticed something on this picture http://cloud.steampowered.com/ugc/594683394294528948/53F99E8B12D9CA1070087E748200EB49B346F479/

If you look above the bit near the procedures line of text ,which is preety much unreadable, u can see next to a picture of some sort of bag with the aperture science logo on it and underneath it directly it says in small letters that are just about readable "special ingrediant from dad's work" Now this therefore begs the question that if the "ingrediant" is from aperture, and it's from her dad's work, then surely it means her dad worked at aperture.
