Postdoc in Applied Math / Scientific Computing

Job ID 2864 Date posted 06/15/2022

Brookhaven National Laboratory (www.bnl.gov) delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.

Organizational Overview

Brookhaven National Laboratory (BNL) is a scientific, extreme scale Data Laboratory in the U.S., New York State, Long Island. We have a lively, fast-growing data science research program at BNL, with a specific focus on the challenges presented by the analysis, interpretation, and use of data at extreme scales and in real-time. The data science program is accompanied by significant computational modeling research effort, in support of the design, planning, analysis, and interpretation of both laboratory and computer experiments and their results. The Computational Science Initiative (CSI - https://www.bnl.gov/compsci/) provides a laboratory-wide umbrella for these activities, bringing together computer scientists, applied mathematicians, and domain scientists to carry out leading-edge research, convert research results into practical solutions that advance domain science, and provide the necessary computing infrastructure services and training to support efficient operation. The position will reside within CSI’s Applied Mathematics group, which conducts research on a variety of applied science and engineering problems involving methods such as optimal experimental design, uncertainty quantification, decision making under uncertainty, modeling and simulation, surrogate and reduced order modeling, extreme-scale data analysis, and scientific machine learning.

Position Description

The Applied Mathematics Group of the Computational Science Initiative (CSI) at Brookhaven National Laboratory (BNL) invites exceptional candidates to apply for a post-doctoral research associate position in applied mathematics, machine learning, and scientific computing. This position offers a unique opportunity to conduct research in emerging interdisciplinary research problems at the intersection of applied mathematics, machine learning, and high-performance computing (HPC) with applications in diverse scientific domains of interest to BNL and the Department of Energy (DOE). Topics of specific interest include: (i) optimal decision-guided data reduction; (ii) feature extraction/engineering in high-dimensional compositional workflows that involve machine learning (ML) models; (iii) Bayesian inference and uncertainty quantification in scientific ML models; (iv) learning/optimization of low-dimensional latent feature spaces for ML surrogates. The position includes access to world-class HPC resources, such as the BNL Institutional Cluster and DOE leadership computing facilities. Access to these platforms will allow computing at scale and will ensure that the successful candidate will have the necessary resources to solve challenging DOE problems of interest.

This program provides full support for a period of two years at CSI with possible extension. Candidates must have received a doctorate (Ph.D.) in applied mathematics, statistics, computer science, or a related field (e.g., mathematics, engineering, operations research, physics) within the past five years. This post-doc position presents a unique chance to conduct interdisciplinary collaborative research in BNL programs with a highly competitive salary.

Essential Duties and Responsibilities:

  • Conduct research in various applied mathematics/machine learning problems in the context of scientific data reduction in compositional workflows.
  • Work in interdisciplinary collaborations with applied domain scientists on various aspects of scientific data generation, processing, and compression.
  • Formulate a high-quality research program in collaboration with mentors in the group.

Position Requirements

Required Knowledge, Skills, and Abilities:

  • Ph.D. in applied mathematics, statistics, computer science, or a related field (e.g., mathematics, engineering, operations research, physics) awarded within the last 5 years
  • Programming experience in machine learning, scientific modeling, or scientific computing.

Preferred Knowledge, Skills, and Abilities:

  • Scientific machine learning / physics-informed machine learning
  • Decision theory, decision making under uncertainty, or optimal design of experiments
  • Bayesian inference, uncertainty quantification, or spatiotemporal statistics
  • Information theory, data compression, signal processing
  • Bayesian optimization, nonlinear/nonconvex optimization, mixed-integer programming
  • Experience in scientific ML applied to domain sciences problems (e.g., in physical sciences, life sciences, or engineering)

BNL policy requires that research associate appointments be made to individuals who have received their doctorate within the past five years.

At Brookhaven National Laboratory, we believe that a comprehensive employee benefits program is an important and meaningful part of the compensation employees receive. Our benefits program includes, but is not limited to:

  • Medical, Dental, and Vision Care Plans
  • Flexible Spending Accounts
  • Paid Time-off and Leave Programs (vacation, holidays, sick leave, paid parental leave
  •  401(k) Plan
  • Flexible Work Arrangements
  • Tuition Assistance, Training and Professional Development Programs
  • Employee Fitness/Wellness & Recreation: Gym/Basketball Courts, Weight Room, Fitness Classes, Indoor Pool, Tennis Courts, Sports Clubs/Activities (Basketball, Ping Pong, Softball, Tennis)
