Old cells in our bodies are constantly being replenished by new ones. These new cells arise from the so-called stem cells. Stem cells enter a process known as “differentiation” where stem cells stop dividing and gradually mature into the cells needed in the body. This image shows tissue from an animal that carries a mutation in a gene essential for differentiation. Each tiny circle is an individual stem cell that never stopped dividing and failed to differentiate.
Arnaldo grew up in Puerto Rico. He did his Bachelors at the University of Puerto Rico in Mayagüez. He then went to UT-Southwestern in Dallas, Texas to study how RNA-binding proteins influence germline stem cell differentiation guided by Michael Buszczak. As a post-doc at Stanford University, Arnaldo is training to become an expert in systems neurodevelopment under the mentorship of Chris Doe and Tom Clandinin. He is particularly interested in how activity within short periods of time during nervous system development affects circuit function for the entire life of the organism. Outside the lab he likes to play soccer, try new restaurants and visit friends and family around the US, Puerto Rico and Turkey.
