Dr. Arnel Salvador is a Professor at the National Institute of Physics. He earned his Bachelor’s degree in Physics from the University of the Philippines Diliman in 1983, graduating Cum Laude. He then pursued his PhD in Physics at the University of Illinois at Urbana-Champaign completing it in 1994, and continued as a Postdoctoral Research Associate until 1997.

Through his career, Dr. Salvador has received numerous distinctions. In 2018, he was honored as an academician by the National Academy of Science and Technology. He was recognized as the Gawad Chancellor Outstanding Researcher at the University of the Philippines Diliman in 2005 and was named the Outstanding Young Scientist by the National Academy of Science and Technology in 2002. His early academic excellence was evident with his membership in Phi Kappa Phi at the University of Illinois at Urbana-Champaign in 1992.

Dr. Salvador has made significant contributions to experimental condensed matter and applied solid-state physics. His pioneering work involves the fabrication of optoelectronic devices using Groups III-V semiconductors grown via molecular beam epitaxy techniques. These devices have applications in semiconductor lasers, photodetectors for optical communication, terahertz emitters, and detectors for the spectroscopic identification of chemical and imaging.

He has produced groundbreaking results in his field, as evidenced by numerous highly cited peer-reviewed technical publications. Dr. Salvador has established an advanced and globally competitive semiconductor research laboratory, dedicated to training and mentoring highly skilled undergraduate and graduate scientists. He has mentored and graduated 33 Master’s students and 12Ph.D. students in Physics and Materials Science and Engineering. His commitment to improving science and technology in the Philippines is further demonstrated by the international collaborations he has set up, enabling his students to gain experience in research laboratories abroad.
