Arlie Petters, Belizean-American mathematical physicist and academic

Arlie Oswald Petters, born on February 8, 1964, is a distinguished Belizean-American mathematical physicist renowned for his pioneering contributions to the field of mathematical astronomy. His illustrious career is marked by significant academic and leadership roles, bridging the realms of theoretical physics and university administration.

A Pioneer in Mathematical Astronomy and Gravitational Lensing

Dr. Petters is widely recognized as a founder of mathematical astronomy, an innovative discipline that applies advanced mathematical tools to complex problems in astrophysics and cosmology. His groundbreaking research primarily focuses on the intricate interplay of gravity and light, particularly through the phenomenon of gravitational lensing.

Gravitational lensing, a prediction of Albert Einstein's theory of general relativity, occurs when the gravitational field of a massive object – such as a galaxy or a galaxy cluster – bends and distorts the light from a distant source. This cosmic magnifying glass effect can create multiple images of the background object, or magnify and brighten it, offering unique insights into the universe's structure, including the distribution of dark matter and dark energy, and the detection of exoplanets.

Petters' work is inherently interdisciplinary, employing sophisticated methodologies drawn from a broad spectrum of scientific fields, including:

A seminal achievement in his career is the authorship of the monograph "Singularity Theory and Gravitational Lensing." This influential work developed a rigorous mathematical theory that provides the foundational framework for interpreting the complex patterns and distortions observed in gravitational lensing phenomena. The book is considered a cornerstone text for researchers in the field, bridging abstract mathematical concepts with tangible astronomical observations.

Academic and Administrative Leadership

Beyond his profound research contributions, Dr. Petters has held significant leadership positions within prominent academic institutions.

At Duke University, where he held the esteemed Benjamin Powell Professorship of Mathematics and was also a Professor of Physics and Economics, he played crucial administrative roles. From 2016 to 2019, he served concurrently as the Dean of Academic Affairs for Trinity College of Arts and Sciences and the Associate Vice Provost for Undergraduate Education. These roles involved overseeing the academic programs, curriculum development, and student experience for a substantial portion of Duke's undergraduate population, demonstrating his commitment to academic excellence and student success.

Demonstrating his leadership capabilities further, Dr. Petters became the Provost at New York University Abu Dhabi (NYUAD) effective September 1, 2020. As Provost, he serves as the chief academic officer of the university, responsible for the overall academic vision, faculty appointments, curriculum, research initiatives, and strategic planning. NYU Abu Dhabi is a distinctive global campus renowned for its highly selective admissions, interdisciplinary curriculum, and commitment to fostering global leaders.

Distinctions and Recognition

Dr. Petters' exceptional achievements have earned him notable recognition. He was appointed a Member of the Order of the British Empire (MBE), an honor bestowed by the British monarch for significant achievements or service to the community. This award acknowledges his distinguished contributions not only to science but also his broader impact.
