Applied Mathematics

Position Openings

Postdoctoral Research Assistant

The Division of Applied Mathematics at Brown University is accepting applications for a postdoctoral research associate in statistics, machine learning, computer science, data science, or applied mathematics. The successful applicant will join a NASA-funded effort to generate new methods for data generation and prediction using spaceborne lidar data. The data are being collected by the Global Ecosystem Dynamics Investigation (GEDI), a multibeam waveform lidar sensor currently in orbit on the International Space Station. The successful applicant will advance NASA capabilities with respect to three issues:

(1) developing a generative waveform model that is representative of sensor noise and other measurement artifacts using a large training data set of coincident airborne and spaceborne lidar data;

(2) development of statistical machine learning models to predict aboveground carbon density using spaceborne lidar in forests and woodlands worldwide; and

(3) improvement of predictive models using semi-supervised learning applied to billions of waveform height measurements from GEDI lidar.

The successful applicant will work directly under the supervision of Dr. Matthew Harrison (Applied Math) and Dr. James Kellner (Institute at Brown for Environment and Society and GEDI co-Investigator). The successful applicant should have a PhD in applied mathematics, biology, computer science, data science, geodesy, geophysics, engineering, machine learning, remote sensing, statistics, or a closely related field. Experience with large datasets is essential. Excellent written and oral communication skills are essential as indicated by a record of peer-reviewed publication, oral presentation, or other means. A strong background in quantitative methods and statistical inference is necessary to succeed in this position. Preference will be given to applicants with exposure to machine learning using large data sets. Applicants with experience using remote sensing, geographic information systems, or other spatial data are desirable but not essential. The successful applicant will be a member of the Division of Applied Mathematics and the Institute at Brown for Environment and Society. The successful applicant will interact with the NASA GEDI Science Team, and with collaborators at the University of Maryland College Park and NASA Goddard Space Flight Center. The initial appointment will be for one year, subject to renewal upon satisfactory performance and funding availability.

All candidates should submit a cover letter, curriculum vitae, and names and contact information for three references. Please apply via mathjobs:

Applications will be reviewed immediately, and the position will remain open until filled.

Application inquiries should be directed to [email protected].

Undergraduate Teaching Assistant (UTA)

Each semester, we seek undergraduate students who are interested in being UTAs for selected APMA courses. UTAs are an integral part of our teaching effort and play an important role.  Responsibilities include assisting with recitation sessions or study sections, holding office hours where students can get guidance on topics arising from the course, and helping review student assignments.  Through peer-to-peer engagement, UTAs can play a very positive role in shaping a student’s perspective on the learning and application of applied mathematics.  Serving as a UTA can also be a learning experience, developing communication skills and reinforcing one’s own knowledge of course topics.

UTAs receive an hourly wage, but we do not currently give course credit for being a UTA. UTA positions are advertised in Workday.  Usually, positions are advertised in mid-April (and then possibly again in mid-September) for the fall semester, and in mid-November (and possibly again in early February) for the spring semester.

For the current academic year 2020-2021, with the three semesters, we are now asking for applications for UTA positions for the spring semester and these should be submitted before November 30. We will begin applications for UTAs for the summer semester in mid-March. This will probably be combined with applications for the following fall semester. Specific dates will be set when the dates for course registration are posted.
