Department of Natural Sciences


Over the last decade, the department of natural sciences at LAU has witnessed remarkable growth in teaching and research. Besides courses intrinsic to its curricula, the department fulfills the university’s Liberal Arts and Sciences in scientific literacy and provides several courses tailored to LAU’s pharmacy, bioinformatics and engineering programs. Our programs emphasize integrated laboratory experiences through which students learn modern experimental techniques using the latest tools.

Graduates may opt to join graduate or professional programs, or they may pursue careers in teaching, medicine, industry (chemical engineering, food processing, cosmetics…), biotechnology, pharmaceuticals, and related fields. LAU also has collaboration agreements with distinguished European universities for joint Ph.D. programs in molecular biology and biotechnology. Candidates perform their experimental work at LAU and register for graduate courses at both LAU and the partner university. More than 50% of our graduate students have joined Ph.D. programs in reputable universities in France, Belgium, Germany, England, Canada and the U.S.
