Costantine Daher, PhD

Dr. Costantine Daher was appointed as interim dean of the Alice Ramez Chagoury School of Nursing in September 2019. Dr. Daher joined LAU as an instructor of biology in 1991 and became an assistant professor in 1998, after earning his PhD in biomedical sciences from the University of Surrey in England. He was then promoted to associate professor in 2005 and full professor in 2016. He served as chair of LAU’s Department of Natural Sciences between 2005 and 2014 and was also appointed assistant dean of the School of Arts and Sciences between September 2014 and August 2018 and interim dean of the School of Arts and Sciences during the academic year 2018-2019.


Scholarly Interests

Dr. Daher has published more than 55 peer-reviewed research articles. His research was originally focused on natural products with specific interests including anti-inflammatory, antioxidant, anti-ulcer and anti-cancer activities.

Lately, Dr. Daher was mostly engaged in drug discovery in cancer therapy. He is working in two directions: targeted and conventional chemotherapy. In targeted chemotherapy, photoactivatable synthetic Ruthenium-based organometallic compounds are used in vitro and in vivo in order to find an effective alternative therapy that helps reduce side effects associated with conventional chemotherapy. 

On the other hand, since platinum-based conventional chemotherapy has been shown to be very effective in treating many types of cancers, Dr. Daher is also heavily engaged in the search for novel platinum II- and platinum IV-based chemotherapeutic agents that could constitute a safe and effective treatment approach for cancer patients.
