Plenty of tutorials will tell you what a memory palace is, but we explore how to actually put them into practice as learning tools. Together—a medical student and a medical student/three-time world memory champion—we've modified the memory techniques used by competitive memorizers, combining them with evidence-based strategies of effective learning, to explore and improve our retention of medicine, languages, and more. Using memory palaces effectively can be challenging without the right approach. We're a nonprofit whose aim is to find the strategies that can make memory techniques an effective piece of any student's learning toolkit. No paywall, no paid products, no ads, no spam—just free, original content.

Alex Mullen


Alex Mullen graduated from Johns Hopkins University in 2014 with degrees in Biomedical Engineering and Applied Mathematics and Statistics. He is currently a medical student at the University of Mississippi. Alex won three world memory championships (2015-17) and is the highest total point scorer in memory sports history. He is the top-ranked memory athlete in the world. Alex is also the 2016 USA Memory Champion. His favorite events are cards and numbers. He is the first person to memorize the order of a deck of playing cards in under 20 seconds and the first to memorize more than 3,000 decimal digits in one hour. When not learning medicine or memorizing cards, Alex is probably walking the dog or eating guac with friends.

Cathy Chen graduated from Princeton University in 2014 with a degree in Chemical and Biological engineering. She is currently a medical student at the University of Mississippi School of Medicine. While Cathy isn't a competitive memorizer, she's talked shop with the world memory champion for years. Cathy works closely with Alex to adapt and enhance the memory palace technique for general learners. She uses their techniques in her daily studies. When she's not helping the memory champ remember where he left his wallet, Cathy's probably texting her sister or taking pics of the dog.
