Cesar Ramon Romero Leguizamon

Cesar Ramon Romero Leguizamon is a Colombian medical doctor and researcher currently serving as a postdoctoral research fellow at Region Hovedstadens Psykiatri under the supervision of Prof. Morgane Thomsen. He previously completed a postdoctoral fellowship at the National Institute on Drug Abuse (NIDA), part of the NIH in Baltimore, USA, and earned his PhD at the Kohlmeier Lab at the University of Copenhagen. His academic appointment is as a Guest Researcher in the Department of Drug Design and Pharmacology within the Faculty of Health and Medical Sciences at the University of Copenhagen.

Dr. Romero-Leguizamon's research focuses on neuroscience, particularly investigating the relationship between stress and addiction through electrophysiological techniques. His work centers on the Laterodorsal Tegmental nucleus (LDT), examining hypercholinergic states, intracellular calcium dynamics, and the role of heteromers using in-vivo microdialysis and optogenetics. His research spans multiple areas including neuropharmacology, addiction mechanisms, stress circuitry, and the neural basis of sleep disorders in Parkinson's disease.

His recent publications demonstrate a strong focus on α-synuclein's role in Parkinson's disease, particularly its effects on sleep-controlling neurons and sex-dependent neuronal responses. His work also explores the intersection of addiction and obesity through GLP-1 and nicotine pathways, as well as neuropeptide effects on neuronal excitability. The research consistently applies advanced techniques including patch clamp electrophysiology, calcium imaging, and optogenetics.

Dr. Romero-Leguizamon has received significant attention for his research, with multiple publications picked up by news outlets and widely shared on social media platforms including X (formerly Twitter) and Facebook. His work has garnered substantial academic interest with numerous readers on Mendeley.

Beyond his scientific work, Dr. Romero-Leguizamon has pursued artistic interests as an actor and theater director, specifically exploring the application of art in medical therapy through Humor Therapy (Doctor Clown) and art-based interventions for addicted patients. He also engages in painting and writing as personal creative outlets.
