I'm special faculty in the Human-Computer Interaction Institute at Carnegie Mellon University. I use the tools of cognitive science (experimentation, computational modeling, and big data analytics) and educational technology to understand how we acquire new knowledge and improve education.
You can contact me by emailing me: pcarvalh at cs dot cmu dot edu. I rarely tweet.
If you are wondering how to pronounce my last name, it sounds like karr-vah-you. The “lh” is a consonant that sounds like the ‘ll’ in the english word ‘million’, if you were to really stretch it out.
