Chadi Calarge M.D., Principal Investigator

As a physician scientist with interest in child and adolescent psychiatry, I have focused my research on examining the long-term effects of psychiatric medications in youth on health, including weight and development, bone health, and iron regulation. I have also been interested in the intersection between psychiatric conditions and psychiatric medications with regard to how each might affect these outcomes and how genetic factors would influence them as well. This includes the role of the gut bacteria in health and illness. The hope is to better understand psychiatric disorders and be able to offer a safer way to treat them.
Griselda Barba Villalobos

I’ve been in the research field for 11+ years and have had the privilege of working with Dr. Chadi Calarge since 2016! The years speak to my passion for the important work we do here. With a Master’s in Counseling (M.Ed.), I’m dedicated to improving mental health, especially for kids and underserved populations. As the lab manager, I ensure our studies run smoothly by overseeing protocols, training staff, and managing our dataset. I’m also involved in creating new protocols and ensuring our research is carried out efficiently and effectively. When opportunities arise, I enjoy attending conferences to stay up to date on various topics like depression, anxiety, OCD, and suicide.
When I’m not in the lab, I’m all about photography! Capturing the shot that inspires a funny, witty, insightful, or mysterious title is my favorite part of this hobby. I hope all our research families enjoy participating in our studies as much as we enjoy working with them!

Elif Naz Kilicarslan
I graduated from Texas A&M university with a dual degree in Neuroscience and Political Science. As a student, I was a member of a research team studying food insecurity and religiously affiliated food provision programs. A collaboration with the TAMU School of Public Health on a survey on folic acid intake among pantry recipients of childbearing age led to my interest in the intersection of nutrition and neurodevelopmental disorders. I started working with the Calarge Lab in the summer of 2023 as a research coordinator on our iron study, where we investigate iron deficiency and brain development in children and adolescents with internalizing disorders. Since then, I have had the opportunity to work on several studies where we look at the effects of psychiatric medications on pediatric populations.

I graduated from Texas A&M University in 2024 with a B.S. in psychology and worked in different developmental psychology research labs throughout my time there as well as volunteering for the Helpline. This led me to becoming really interested in learning more about internalizing disorders such as depression and anxiety. As a research coordinator for the lab, I mostly work on recruiting new families to participate in our research and run the research visits. Outside of the lab, I like to read, sing, and play video games.
