General Description

Salary: $63,460 - $100,000 per year

The Johns Hopkins University's Department of Applied Mathematics and Statistics invites applicants for one or more positions as Postdoctoral Fellow. Candidates must have completed their Ph.D. prior to their appointment start date, and no later than 08/30/2026, and show definite promise in research and teaching. The teaching load will be at most one course each semester, and often as little as one course per year, depending on funding and the needs of the department, so that the appointee will have ample time for research. The appointment is for two years, with the possibility of renewal, depending on funding availability.

The successful candidate will work with Professor Nicolas Loizou on foundational and algorithmic aspects of min-max optimization, with applications to machine learning, artificial intelligence, and large-scale reinforcement learning. The project focuses on developing new mathematical foundations and efficient algorithms tailored specifically to min-max problems, moving beyond the traditional paradigm of adapting minimization methods to saddle-point settings. Research directions include stochastic min-max optimization, accelerated and anchor-type methods, alternating-update strategies, proximal-gradient-type algorithms, nonconvex min-max optimization, efficient sampling schemes, and applications to training deep neural networks. The ideal candidate will have a strong background in optimization, applied mathematics, probability, theoretical machine learning, or computational mathematics, with demonstrated interest in the analysis and design of modern large-scale learning algorithms.

Applicants are asked to submit (a) an AMS standard coversheet; (b) a curriculum vitae; (c) a description of research interests, and have at least three letters of recommendation submitted.

Applicants should apply using: https://apply.interfolio.com/184958

Additionally, the candidates should contact Professor Loizou via email at nloizou@jhu.edu , with a message containing "Postdoc_JHU_OptML_Lab" in the subject line, discussing any potential overlap of research interests with Professor Loizou.

Applications received by 06/15/2026 will be guaranteed full consideration; early application is advisable.

Vaccine Requirements

Johns Hopkins University strongly encourages, but no longer requires, at least one dose of the COVID-19 vaccine. The COVID-19 vaccine does not apply to positions located in the State of Florida. We still require all faculty, staff, and students to receive the seasonal flu vaccine. Exceptions to the COVID and flu vaccine requirements may be provided to individuals for religious beliefs or medical reasons. Requests for an exception must be submitted to the JHU vaccination registry. This change does not apply to the School of Medicine (SOM). SOM hires must be fully vaccinated with an FDA COVID-19 vaccination and provide proof of vaccination status. For additional information, applicants for SOM positions should visit https://www.hopkinsmedicine.org/coronavirus/covid-19-vaccine/ and all other JHU applicants should visit https://covidinfo.jhu.edu/health-safety/covid-vaccination-information/.

The following additional vaccine requirements may apply, depending upon your campus. Please contact the hiring department for more information. The pre-employment physical for positions in clinical areas, laboratories, working with research subjects, or involving community contact requires documentation of immune status against Rubella (German measles), Rubeola (Measles), Mumps, Varicella (chickenpox), Hepatitis B and documentation of having received the Tdap (Tetanus, diphtheria, pertussis) vaccination. This may include documentation of having two (2) MMR vaccines; two (2) Varicella vaccines; or antibody status to these diseases from laboratory testing. Blood tests for immunities to these diseases are ordinarily included in the pre-employment physical exam except for those employees who provide results of blood tests or immunization documentation from their own health care providers. Any vaccinations required for these diseases will be given at no cost in our Occupational Health office.
