Ojukwu Collins Uchenna, a medical student at Gullas College of Medicine and the current NAS Cebu Chapter President, is building a strong profile in medical research, leadership, and community engagement. Originally from Anambra State, Nigeria, he combines academic focus with a commitment to public health advocacy.

His research spans oncology, neurophysiology, and public health. He has a solo-authored study that reviews the therapeutic potential of plant-based compounds in cancer treatment, with attention to molecular pathways and drug delivery innovations. Another co-authored paper investigates the neurological effects of marijuana use in patients with cannabis-induced psychosis, using fMRI and biochemical analysis to support its findings.

In his solo-authored paper on natural compounds and cancer treatment, Uchenna explores how plant-based substances—such as flavonoids, polyphenols, and terpenoids—can help fight cancer. He explains how these natural molecules can trigger cancer cell death, reduce harmful stress in the body, and block the signals that allow tumors to grow. His work positions these compounds as promising options to support or even enhance traditional cancer treatments.

In another major project, Uchenna collaborated in a study on how marijuana affects the brain, particularly in people who developed psychotic disorders from frequent cannabis use. Using brain scans and lab tests, they examined 30 patients and found some striking results: the part of the brain responsible for memory (the hippocampus) had shrunk by over 12%, while the area linked to emotion (the amygdala) had grown by nearly 10%. They also saw a sharp increase in dopamine, a brain chemical involved in mood and behavior.

These discoveries point to the need for better screening and mental health assessments for people who regularly use marijuana. The study suggests that brain imaging should become a routine part of psychiatric care and calls for stronger public education to protect people at risk—especially young and vulnerable populations.

Beyond these two key studies, Uchenna has also worked on several other researches. He co-authored a paper on how children’s bone marrow reacts to different levels of malaria infection, published via African Journals Online (AJOL). 

Uchenna has also contributed to studies on clinical behavior, pediatric malaria, and sustainable pharmaceutical practices. In addition to his academic work, he serves as President of the Nigerian Students Association (NSA) Cebu and has been active in student leadership and medical outreach initiatives.

Through his research and advocacy, Uchenna reflects Gullas College of Medicine’s aim to train doctors who are both scientifically grounded and socially responsible.
