General Description
Dr. Nicolas Christianson is seeking a highly motivated postdoctoral researcher to join his research group at Johns Hopkins University beginning in Fall 2026. The position will be based in the Department of Computer Science, with opportunities to engage with the broader Johns Hopkins research ecosystem through the Data Science and AI Institute (DSAI) and the Ralph O'Connor Sustainable Energy Institute (ROSEI).
The postdoctoral researcher will work on problems in data-driven and machine learning-augmented algorithm design, AI and machine learning for optimization, and reliable, robust decision-making under uncertainty in complex systems. The ideal candidate will be interested in developing rigorous algorithmic and methodological foundations and bringing these ideas to bear on impactful applications in sustainable computing infrastructure, data center workload and energy management, power and energy systems, and related domains. Applicants with strong mathematical, algorithmic, or machine learning backgrounds are encouraged to apply, even if their prior work has not focused on energy or computing systems.
This is a full-time, on-site postdoctoral position with an initial appointment of 12 months and the possibility of extension based on performance and funding. Strong candidates need not meet every qualification listed below.
Qualifications
- PhD in Computer Science, Electrical Engineering, Operations Research, Applied Mathematics, or a related technical field
- Strong publication record in relevant peer-reviewed venues, such as ACM SIGMETRICS, ACM e-Energy, NeurIPS, ICML, COLT, SODA, or related conferences and journals
- Strong technical background in one or more of the following:
- Algorithms, especially online algorithms, approximation algorithms, and learning-augmented algorithms
- Optimization, especially stochastic optimization, machine learning for optimization, and decision-focused learning
- Uncertainty quantification, including conformal prediction
- Machine learning theory, including online learning and bandits
- Interest or experience in working on topics related to computer systems, sustainable computing, data centers, power systems, smart grids, or electricity markets
- Proficiency in Python and machine learning frameworks (e.g., PyTorch)
- Experience with optimization tools such as Gurobi and CVXPY
- Experience building high-quality research code, running computational experiments, or contributing to open-source software.
- Ability to lead research projects independently, from problem formulation through analysis, implementation, and publication
- Excellent written and oral communication skills.
- Interest in working in a collaborative and interdisciplinary environment
Application Instructions
Applicants should submit a curriculum vitae, a research statement, two representative publications, and at least two letters of reference.

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.
