Sui Tang receives Hellman Family Faculty Fellowship

The Mathematics Department congratulates Assistant Professor Sui Tang on receiving a Hellman Family Faculty Fellowship. The fellowship aims to advance the careers of junior faculty through endowed research fellowships at the University of California.

Emily Lopez receives Thomas More Storke Award for Excellence

The Mathematics Department congratulates CCS undergraduate student Emily Lopez on receiving the Thomas More Storke Award for Excellence. The award is the campus’s highest student honor and is given to a graduating senior in recognition of outstanding scholarship and extraordinary service to the university, its students, and the community. After graduation, Emily plans to pursue her Ph.D. in applied mathematics at Cornell University.

Ruimeng Hu receives Regents' Junior Faculty Fellowship Award

The Mathematics Department congratulates Assistant Professor Ruimeng Hu on receiving the Regents' Junior Faculty Fellowship Award. This award, presented by the UCSB Academic Personnel Office, helps eligible junior faculty develop a substantial record in research and creative work necessary for advancement to tenure. Ruimeng Hu’s research focuses on learning stochastic games on large graphs and graphons.

Katy Craig Wins NSF CAREER Award

Professor Craig’s primary research goals are to use partial differential equations and optimal transport to develop the mathematical foundations of machine learning, motivated in part by challenges that arise when applying machine learning for scientific discovery in particle physics. She was just awarded an NSF Career Grant to pursue these goals.

NSF describes the CAREER program as offering their most prestigious awards in support of early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organization.

Recruitment: Postdoctoral Scholar - Applied and Computational Mathematics

The Department of Mathematics at University of California, Santa Barbara invites applications for two postdoctoral positions broadly in the area of applied and computational mathematics. Candidates are expected to have expertise in at least one of the following areas: analysis of electronic structure models, multiscale modeling, tensor networks, or quantum physics. Candidates with physics, chemistry, or materials science backgrounds who have extensive experience in terms of method development are also welcome. The positions permit the teaching of two under/graduate courses during the academic year in the appropriate teaching title.

A Clear Description of Turbulent Water

Update: This research is featured in a new article in Scientific American!

An international team of mathematicians, led by UCSB Professor Björn Birnir, has published a complete mathematical description of boundary layer turbulence. The paper, published in the journal Physical Review Research, synthesizes decades of work on the topic to provide a mathematical formula describing the turbulance caused when flow of water, air, or other fluids interacts with a boundary such as a pipe wall or the surface of the earth. Boundary layer interactions are important to many scientific and engineering fields, from meteorology to optimizing the aerodynamics of cars and aircraft.

Recruitment: Lecture Pool

The Department of Mathematics at the University of California, Santa Barbara invites applications for a pool of qualified temporary lecturers to teach undergraduate or graduate Mathematics courses. Screening of applicants is ongoing and will continue as needed. The number of positions varies from quarter to quarter, depending on the needs of the department. Positions may range from one quarter to one year with the possibility of reappointment depending on performance and further departmental need.

The successful applicant will be a broadly trained mathematician who is dedicated to teaching.

Recruitment: Visiting Assistant Professor

VISITING POSITIONS: One or more special one-year visiting assistant professorships may be available, with possibility of renewal for additional years, up to three years in total. These positions carry a teaching load of 4.5 one- quarter courses per year. Excellence in research, potential for interaction with faculty at UC Santa Barbara and evidence of (or potential for) good teaching are desired.
