项目介绍

2025年3月13日

We are looking for two highly motivated individuals to pursue a Ph.D. in algorithms, data structures, and data analysis. The research team develops algorithms and data structures with provable guarantees, by leveraging theoretical insights to obtain state-of-the-art practical algorithms. Currently, we have a focus on randomized algorithms and probabilistic data structures such as data sketches, Bloom filters, and hash functions. We are also interested in implementing and developing efficient data structures for subroutines that appear in data science algorithms. The positions have a strong mathematical flavor, and the students will spend a big part of their work analyzing algorithms theoretically. Several directions of the project are possible and will be determined in collaboration with the Ph.D. candidate.

Third-cycle subject: Computer Science

Supervision: Professor Aristides Gionis and Assistant Professor Ioana-Oriana Bercea

What we offer

• The possibility to study in a dynamic and international research environment in collaboration with industries and prominent universities from all over the world.
• A workplace with many employee benefits and monthly salary according to KTH’s Doctoral student salary agreement.
• A postgraduate education at an institution that is active and supportive in matters pertaining to working conditions, gender equality and diversity as well as study environment.
• Work and study in Stockholm, close to nature and the water.
• Help to relocate and be settled in Sweden and at KTH.

Admission requirements

To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

• passed a second cycle degree (for example a master’s degree), or
• completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
• acquired, in some other way within or outside the country, substantially equivalent knowledge

Good command of English orally and in writing is required to publish and present results at international conferences. 

In addition to the above, there is also a mandatory requirement for English equivalent to English B/6.

Selection

In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

• independently pursue his or her work
• collaborate with others,
• have a professional approach,
• analyse and work with complex issues,
• have a strong background and passionate interest in algorithm design and mathematics (especially in probability and optimization), and
• present an outstanding academic track record.

Applicants must hold or be about to receive a Master of Science degree.

A suitable background is, for example, a degree in computer science, mathematics, electrical engineering, or possibly technical physics with a theoretical specialization. We are looking for a strongly motivated person.

Previous participation in International Mathematical Olympiads and/or International Olympiads in Informatics is an asset.

After the qualification requirements, great emphasis will be placed on personal skills.

Target degree: Doctoral degree

Information regarding admission and employment

Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ‘ time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time. In the case of studies that are to be completed with a licentiate degree, the total period of employment may not be longer than what corresponds to full-time doctoral education for two years.
