Maria Luísa Vasconcelos

Maria Luísa Vasconcelos serves as Principal Investigator at the Champalimaud Foundation in Lisbon, Portugal, where she leads the Vasconcelos Lab focused on understanding the neural basis of innate behaviors in Drosophila melanogaster. Her research group operates within Champalimaud Research, investigating how defined neural circuits control specific behavioral responses through a multidisciplinary approach combining behavioral analysis, genetics, imaging, and electrophysiology.

Dr. Vasconcelos's research program centers on innate behaviors, particularly courtship, aggression, and sensory processing in fruit flies. Her laboratory has made significant contributions to understanding female receptivity during courtship, demonstrating how ovipositor extrusion serves as a signal for mating acceptance and facilitates the transition from courtship to copulation. Key research areas include the neural control of egg-laying behavior, suppression of escape responses during mating, and sensory processing in brain regions like the lateral horn. Her work has revealed how specific neural populations process environmental cues and generate context-appropriate behavioral responses, with particular emphasis on reproductive behaviors and social interactions.

An analysis of Dr. Vasconcelos's publication record shows a clear evolution from foundational work on neural circuit organization to increasingly sophisticated investigations of behavioral mechanisms. Her recent publications (2021-2023) demonstrate growing sophistication in circuit-level manipulations and behavioral analysis, with a consistent focus on how neural circuits control behavioral transitions during mating. The research increasingly incorporates advanced techniques to map and manipulate specific neural populations, revealing how relatively simple nervous systems can generate complex, adaptive behaviors.

Dr. Vasconcelos mentors several students in her laboratory, including PhD candidate Saheli Roy (INPDP program since 2021) and Master's students Sara Santos and Vitor Silva. Her team also includes postdoctoral researcher Nuno Machado, indicating an active research group with multiple levels of trainees and a productive mentorship environment.

The Vasconcelos Lab operates within the Champalimaud Research structure, utilizing advanced neuroscience facilities to investigate the neural basis of behavior. The lab's work contributes significantly to understanding how neural circuits process information and generate behavioral outputs, with implications for understanding neural circuit function across species and potential relevance to neurological conditions affecting behavior.
